Software Download Process

Use the software download procedure to upgrade to a later version, or downgrade to an earlier version, of an operating system. This section describes the software download process for the Cisco MDS SAN-OS and includes the following topics:

Determining the Software Version

Downloading Software

Selecting the Correct Software Image for an MDS 9200 Series Switch

Migrating from Supervisor-1 Modules to Supervisor-2 Modules

Configuring Generation 2 Switching Modules

Determining the Software Version

To determine the version of Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.

To determine the version of Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, view the Switches tab in the Information pane, locate the switch using the IP address, logical name, or WWN, and check its version in the Release column.


Note We strongly recommend that you use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.


Downloading Software

The Cisco MDS SAN-OS software is designed for mission-critical high availability environments. To realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend that you install dual supervisor modules.

To download the latest Cisco MDS SAN-OS software, access the Software Center at this URL:

http://www.cisco.com/public/sw-center

See the following sections in this release note for details on how you can nondisruptively upgrade your Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Fabric Manager to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can happen nondisruptively or disruptively depending on the current configuration of your switch and the reason.

Compatibility check is done:
Module  bootable          Impact  Install-type  Reason
------  --------  --------------  ------------  ------
     1       yes  non-disruptive       rolling
     2       yes      disruptive       rolling  Hitless upgrade is not supported
     3       yes      disruptive       rolling  Hitless upgrade is not supported
     4       yes  non-disruptive       rolling
     5       yes  non-disruptive         reset
     6       yes  non-disruptive         reset

At a minimum, you need to disable the default device alias distribution feature using the no device-alias distribute command in global configuration mode. The show incompatibility system bootflash:1.3(x)_filename command determines which additional features need to be disabled.


Note Refer to the "Determining Software Compatibility" section of the Cisco MDS 9000 Family CLI Configuration Guide for more details.

Selecting the Correct Software Image for an MDS 9100 Series Switch

The system and kickstart image that you use for an MDS 9100 series switch depends on which switch you use, as shown in Table 3.

Table 3 Software Images for MDS 9100 Series Switch

Switch

MDS 9134, MDS 9124, Cisco Fabric Switch for HP BladeSystem, or Cisco Fabric Switch for IBM BladeCenter

Filename begins with m9100-s2ek9


Selecting the Correct Software Image for an MDS 9200 Series Switch

The system and kickstart image that you use for an MDS 9200 series switch depends on which switch you use, as shown in Table 4.

Use the show module command to display the type of supervisor module in the switch. For a Supervisor-1 module, the output might look like this:

switch# show module
Mod  Ports  Module-Type                      Model              Status
---  -----  -------------------------------- ------------------ ------------

6    0      Supervisor/Fabric-1              DS-X9530-SF1-K9    ha-standby

For a Supervisor-2 module, the output might look like this:

switch# show module
Mod  Ports  Module-Type                      Model              Status
---  -----  -------------------------------- ------------------ ------------
...
...
7    0      Supervisor/Fabric-2              DS-X9530-SF2-K9    active *
8    0      Supervisor/Fabric-2              DS-X9530-SF2-K9    ha-standby

Migrating from Supervisor-1 Modules to Supervisor-2 Modules

As of Cisco MDS SAN-OS Release 3.0(1), the Cisco MDS 9509 and 9506 Directors support both Supervisor-1 and Supervisor-2 modules. Supervisor-1 and Supervisor-2 modules cannot be installed in the same switch, except during migration. Both the active and standby supervisor modules must be of the same type, either Supervisor-1 or Supervisor-2 modules. For Cisco MDS 9513 Directors, both supervisor modules must be Supervisor-2 modules.


Caution Migrating your supervisor modules is a disruptive operation.


Note Migrating from Supervisor-2 modules to Supervisor-1 modules is not supported.


To migrate from a Supervisor-1 module to a Supervisor-2 module, refer to the step-by-step instructions in the Cisco MDS 9000 Family CLI Configuration Guide.

Configuring Generation 2 Switching Modules

The Cisco MDS 9500 Multilayer Directors are designed to operate with any combination of Cisco MDS 9000 Generation 1 and Generation 2 modules. However, there are limitations to consider when combining the various modules and supervisors in the Cisco MDS 9500 Series platform chassis. The references listed in this section provide specific information about configurations that combine different modules and supervisors.

For information on configuring Generation 2 switching modules, refer to the Configuring Generation 2 Switching Modules chapter in the the Cisco MDS 9000 Family CLI Configuration Guide.

For information on port index availability, refer to the "Port Index Availability" section in the Product Overview chapter of the Cisco MDS 9500 Series Hardware Installation Guide.

Upgrading an MDS 9222i Switch

Upgrading Your Version of Cisco Fabric Manager

As of Cisco SAN-OS Release 3.2(1), Cisco Fabric Manager is no longer packaged with a Cisco MDS 9000

Family switch. It is included on the CD-ROM that ships with the switch. You can install Fabric Manager from the CD-ROM or from files that you download.

Installing Cisco Fabric Manager is a multi-step process that involves installing a database, as well as Fabric Manager. The complete installation instructions are provided in the "Installation of Cisco MDS SAN-OS and Fabric Manager" section in the Cisco MDS 9000 Family Fabric Manager Configuration Guide, and are available on-screen once you launch the Fabric Manager installer from the CD-ROM.


Note When upgrading Fabric Manager, refer to the supported upgrade path shown in Table 6. For example, when upgrading from SAN-OS Release 3.1(x) to Release 3.3(3), you will need to upgrade from Release 3.1(x) to Release 3.2(x) and then upgrade to Release 3.3(3).

Note Fabric Manager Server can not be installed on an Active Directory Server when using PostgreSQL, Fabric Manager servers are domain controllers and can not create local PostgreSQL user accounts.


Upgrading from Release 3.1(2c) with the PostgreSQL Patch

To upgrade Fabric Manager to Release 3.3(3) from the UBS special version of 3.1.2c with the PostgreSQL patch, do the following:


Step 1 Upgrade Fabric Manager to Release 3.2(1b), pointing to the same PostgreSQL database which was used by Release 3.1.2c.

Step 2 When the installation is complete, stop the Fabric Manager server.

Step 3 Run PM.sh s located in $InstallDir/bin to re-index the rrd files in the PostgreSQL database.

Step 4 Upgrade Fabric Manager to Release 3.3(3) by running the Release 3.3(3) installer.

Step 5 Discover the fabric again.

Step 6 Add the fabric back into the PM collection. This starts the PM collection.


The Fabric Manager Installation Process Overview

The following section presents the flow of the installation process at a high level. Review these guidelines before you begin the installation process.

1. Verify supported software. Cisco Fabric Manager and Device Manager have been tested with the following software:

Windows 2000 SP4, 2003 SP2, XP SP2

Redhat Linux (2.6 Kernel)

Solaris (SPARC) 8 and 10

VMWare Server 1.0:

Base Operating System: Windows 2000 SP4 / Virtual Operating System: Windows XP SP2

Base Operating System: Windows 2000 SP4 / Virtual Operating System: Windows 2000 SP4

Java Sun JRE and JDK 1.5(x) and JRE 1.6 are supported

Java Web Start 1.2, 1.0.1, 1.5, 1.6


Note Do not use Java 1.6 Update 13.


Firefox 1.5 and 2.0

Internet Explorer 6.x, and 7.0


Note Internet Explorer 7.0 is not supported on Windows 2000 SP4.


Oracle Database 10g Express

PostgreSQL 8.2 (Windows and Linux)

PostgreSQL 8.1 (Solaris)

Cisco ACS 3.1 and 4.0

PIX Firewall

IP Tables

SSH v2

Global Enforce SNMP Privacy Encryption

HTTPS

2. Ensure data migration when upgrading Cisco Fabric Manager from Cisco SAN-OS Releases 3.1(2b) and later.

If you are upgrading Cisco Fabric Manager in Cisco SAN-OS Releases 3.1(2b) and later, be aware that data is migrated from the Hypersonic HSQL database to either the PostgreSQL database or Oracle Database 10g Express during the installation. Data is also migrated from Oracle Database 10g Express to Oracle Database 10g Express. If you migrate the database from Oracle to Oracle, the schema is updated. Refer to Table 6 for information on the supported upgrade path.

3. Ensure data migration when upgrading Cisco Fabric Manager from releases prior to Cisco SAN-OS Releases 3.1(2b).

If you are upgrading Fabric Manager in a Cisco SAN-OS Release prior to 3.1(2b), be aware that data is migrated from the Hypersonic HSQL database to either the PostgreSQL database or the Oracle Database 10g Express during the installation. The Fabric Manager Installer installs the PostgreSQL database on Windows. If you want to install the PostgreSQL database on Solaris or Linux, or if you want to install the Oracle Database 10g Express database, follow the instructions in the "Installation of Cisco MDS SAN-OS and Fabric Manager" section in the Cisco MDS 9000 Family Fabric Manager Configuration Guide. Refer to Table 6 for information on the supported upgrade path.

4. If you are upgrading a previous installation of Fabric Manager, make sure the previous installation is installed and running. Do not uninstall the previous version. If the previous version is uninstalled, the database will not be migrated and your server settings will not be preserved.

5. Select the database.

If you want to use the Oracle Database 10g Express, you must install the database and create a user name and password before continuing with the Fabric Manager installation. We recommend the Oracle Database 10g Express option for all users who are running Performance Manager on large fabrics (1000 or more end devices).

If you want to install the PostgreSQL database, you must disable any security software you are running as PostgreSQL may not install certain folders or users. You must also log in as a Superuser before you start the installation.

6. Install Fabric Manager from the CD-ROM or from files that you download from Cisco.com at the following website:

http://cisco.com/cgi-bin/tablebuild.pl/mds-fm

Installing Fabric Manager on Solaris

This section describes how to install Fabric Manager on Solaris.

To install Fabric Manager on Solaris, follow these steps:


Step 1 Set Java 1.5 or 1.6 to the path that is to be used for installing Fabric Manager.

Step 2 Install the database that is to be used with Fabric Manager.

Step 3 Copy the Fabric Manager jar file m9000-fm-3.3.3.jar from the CD-ROM to a folder on the Solaris workstation.

Step 4 Launch the installer using the following command:

java -Xms512m -Xmx512m -jar m9000-fm-3.3.3.jar

Step 5 Follow the onscreen instructions provided in the Fabric Manager management software setup wizard.



Note If you use a Java JDK instead of a JRE on Solaris, you might encounter a problem trying to install the Device Manager from a web browser. This can happen because the installer heap limit of 256 MB is not sufficient. If you have this problem, save the jnlp link as file, increase the heap limit to 512 MB, and run javaws element-manager.jnlp at the shell prompt.


Installing Fabric Manager on Windows

This section describes how to install Fabric Manager on Windows.


Note Fabric Manager Server can not be installed on an Active Directory Server when using PostgreSQL, Fabric Manager servers are domain controllers and can not create local PostgreSQL user accounts.



Note If you are running Fabric Manager Server on Windows and using the PostgreSQL database, you should examine your Windows Active Directory environment for organizational units (OUs) and make the change recommended below to ensure that Fabric Manager Server does not periodically stop working.

On a Windows system, the Microsoft Active Directory applies a Group Policy Object (GPO) to the Fabric Manager Server. The GPO does not recognize the local user PostgreSQL because it is not in the GPO allow list. As a result, the GPO removes it, and the PostgreSQL database stops working.

To avoid this situation, you should move the Fabric Manager Server to its own OU and apply the same feature settings as the original OU, but remove the local user account to log in as a service.


If your server is running Terminal Services in Application mode, or if you are running Citrix Metaframe or any variation thereof, you need to issue the following command on the DOS prompt before installing Fabric Manager Server.

1. Open a command-line prompt: Start > Run, then type cmd and press Return.

2. At the command prompt type: user /install.


Note Do not close the command line window. This must remain open for the entire duration of the install.


The following is an example of the output of this command:

C:\Documents and Settings\user.domain>USER /INSTALL

User session is ready to install applications.

3. Follow all steps needed to install Fabric Manager, Fabric Manager Server, and Device Manager. See the instructions later in this section.

4. When the installation is complete, at the command prompt, type user /execute and press Return. Then type exit and press Return.

The following is an example of the output of this command:

C:\Documents and Settings\user.domain>USER /execute
User session is ready to execute applications.

To install Fabric Manager on Windows, follow these steps:


Step 1 Click the Install Management Software link.

Step 2 Choose Management Software > Cisco Fabric Manager.

Step 3 Click the Installing Fabric Manager link.

Step 4 Select the drive for your CD-ROM.

Step 5 Click the FM Installer link.

Step 6 Follow the onscreen instructions provided in the Fabric Manager Installer 3.3(3).


To install Device Manager on your workstation, follow these steps:


Step 1 Enter the IP address of the switch in the Address field of your browser.

Step 2 Click the Cisco Device Manager link in the Device Manager installation window.

Step 3 Click Next to begin the installation.

Step 4 Follow the onscreen instructions to complete the installation of Device Manager.


General Upgrading Guidelines

Use the following guidelines when upgrading to Cisco MDS SAN-OS Release 3.3(3):

Install and configure dual supervisor modules.

Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.

Follow the recommended guidelines for upgrading a Cisco MDS 9124 Switch as described in "Upgrading a Cisco MDS 9124 Switch" section.

Follow the guidelines for upgrading a single supervisor switch as described in "Performing a Disruptive Upgrade on a Single Supervisor MDS Family Switch" section.

Be aware that some features impact whether an upgrade is disruptive or nondisruptive:

Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively upgraded. See Table 7 for the nondisruptive upgrade path for all SAN-OS releases.

SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write acceleration, is disrupted during an upgrade. SSM Fibre Channel traffic is not.

Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MPS-14/2 module, the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.

Inter-VSAN Routing (IVR): With IVR enabled, you must follow additional steps if you are upgrading from Cisco SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the "Upgrading with IVR Enabled" section for these instructions.

FICON: If you have FICON enabled, the upgrade path is different. See the "FICON Supported Releases and Upgrade Paths" section.

Use Table 7 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.3(3). Find the image release number you are currently using in the Current column of the table and use the path recommended.


Note On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1a), or Release 3.3(1c) to SAN-OS Release 3.3(3) fails when there is an active FC-Redirect configuration (created by Cisco SME or Cisco DMM applications) on the switch. An active FC-Redirect configuration is defined as:

FC-Redirect configuration for hosts or target connected locally

FC-Redirect configuration created by application running on that switch.

If an upgrade is attempted when an active configurations is present, the switch will go into a disruptive upgrade.



Note The software upgrade information in Table 7 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and SSM intelligent services traffic.

Upgrading with IVR Enabled

An Inter-Switch Link (ISL) flap resulting in fabric segmentation or a merge during or after an upgrade from Cisco MDS SAN-OS Release 2.0(x) to a later image where IVR is enabled might be disruptive. Some possible scenarios include the following:

FCIP connection flapping during the upgrade process resulting in fabric segmentation or merge.

ISL flap results in fabric segmentation or merge because of hardware issues or a software bug.

ISL port becomes part of PCP results in fabric segmentation or merge because of a port flap.

If this problem occurs, syslogs indicate a failure and the flapped ISL could remain in a down state because of a domain overlap.

This issue was resolved in Cisco SAN-OS Release 2.1(2b); you must upgrade to Release 2.1(2b) before upgrading to Release 3.3(3). An upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to Release 2.1(2b) when IVR is enabled requires that you follow the procedure below, and then follow the upgrade guidelines listed in the "Upgrading Your Version of Cisco Fabric Manager" section. If you have VSANs in interop mode 2 or 3, you must issue an IVR refresh for those VSANs.

To upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to Release 2.1(2b) for all other VSANs with IVR enabled, follow these steps:


Step 1 Configure static domains for all switches in all VSANs where IVR is enabled. Configure the static domain the same as the running domain so that there is no change in domain IDs. Make sure that all domains are unique across all of the IVR VSANs. We recommend this step as a best practice for IVR-non-NAT mode. Issue the fcdomain domain id static vsan vsan id command to configure the static domains.


Note Complete Step 1 for all switches before moving to Step 2.


Step 2 Issue the no ivr virtual-fcdomain-add vsan-ranges vsan-range command to disable RDI mode on all IVR enabled switches. The range of values for a VSAN ID is 1 to 4093. This can cause traffic disruption.


Note Complete Step 2 for all IVR enabled switches before moving to Step 3.


Step 3 Check the syslogs for any ISL that was isolated.

2005 Aug 31 21:52:04 switch %FCDOMAIN-2-EPORT_ISOLATED: 
%$VSAN 2005%$ Isolation of interface 
port-channel 52 (reason: unknown failure)
2005 Aug 31 21:52:04 switch %FCDOMAIN-2-EPORT_ISOLATED: %$VSAN 2005%$ 
Isolation of interface port-channel 51 
(reason: domain ID assignment failure)

Step 4 Issue the following commands for the isolated switches in Step 3:

switch(config)# vsan database
switch(config-vsan-db)# vsan vsan-id suspend
switch(config-vsan-db)# no vsan vsan-id suspend

Step 5 Issue the ivr refresh command to perform an IVR refresh on all the IVR enabled switches.

Step 6 Issue the copy running-config startup-config command to save the RDI mode in the startup configuration on all of the switches.

Step 7 Follow the normal upgrade guidelines for Release 2.1(2b). If you are adding new switches running Cisco MDS SAN-OS Release 2.1(2b) or later, upgrade all of your existing switches to Cisco SAN-OS Release 2.1(2b) as described in this workaround. Then follow the normal upgrade guidelines for Release 3.3(3).


Note RDI mode should not be disabled for VSANs running in interop mode 2 or interop mode 3.



Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.3(3)

Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode, which is the default for releases prior to Release 3.0(1).


Note To avoid any traffic disruption, modify the configuration of the SSM ports as described below, before upgrading a SAN-OS software image prior to Release 3.3(3).


For more information on upgrading SAN-OS software, see the "Upgrading Your Cisco MDS SAN-OS Software Image" section.

If the configuration is not updated before the upgrade, the installation process for the new image will automatically convert all ports configured in auto mode to Fx mode. This change in mode might cause a disruption if the port is currently operating in E mode.

To upgrade the image on your SSM without any traffic disruption, follow these steps:


Step 1 Verify the operational mode for each port on the SSM using the show interface command:

switch# show interface fc 2/1 - 32
fc2/1 is up
    Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
    Port WWN is 20:4b:00:0d:ec:09:3c:00
    Admin port mode is auto             <-------- shows port is configured in auto mode
    snmp traps are enabled
    Port mode is F, FCID is 0xef0300   <-------- shows current port operational mode is F
    Port vsan is 1
    Speed is 2 Gbps
    Transmit B2B Credit is 3

Step 2 Change the configuration for the first port of the quad when the admin port mode is auto. (A quad is a group of four ports, supported by a data path processor (DPP). The groups are 1 to 4, 5 to 8, 9 to 12, and so on.) Do not leave the port mode set to auto.

a. Set the port admin mode to E or Fx if the current operational port mode is E, TE, F or FL.

switch# config t
switch(config)# interface fc 2/1
switch(config-if)# switchport mode fx

b. Set the port admin mode to E if the current operational port mode is E:

switch# config t
switch(config)# interface fc 2/5
switch(config-if)# switchport mode e

Step 3 Change the configuration for ports 2, 3, and 4 of the quad:

a. Set the admin port mode to Fx if the admin port mode of these ports is E, TE, or auto.

switch# config t
switch(config)# interface fc 2/2
switch(config-if)# switchport mode fx

b. If the first port in the port group has admin mode E or if the port is operational in E port mode, change the admin state of ports 2, 3, and 4 to shutdown.

switch# config t
switch(config)# interface fc 2/2
switch(config-if)# shutdown

Step 4 Save the running configuration to the startup configuration before the upgrade procedure to ensure that the changes are preserved during and after the upgrade. To save the configuration, enter the following command:

switch# copy running-config startup-config

Upgrading the SSI Image on Your SSM

Use the following guidelines to nondisruptively upgrade the SSI image on your SSM:

Install and configure dual supervisor modules.

SSM intelligent services traffic on SSM ports is disrupted during upgrades. Fibre Channel switching traffic is not disrupted under the following conditions:

Upgrade the SSI boot images on the SSMs on the switch to a release version supported by your Cisco SAN-OS release. Refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage Service Interface Images.

All SSM applications are disabled. Use the show ssm provisioning command to determine what applications are configured. Use the no ssm enable feature command to disable these applications.

No SSM ports are in auto mode. See the "Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.3(3)" section.

The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld command to determine your EPLD version. Refer to the Cisco MDS 9000 Family Release Notes for Cisco MDS 9000 EPLD Images to upgrade your EPLD image.

Refer to the Cisco Data Center Interoperability Support Matrix and the "Managing Modules" chapter in the Cisco MDS 9000 Family CLI Configuration Guide, Release 3.x, for information on upgrading your SSM.


Caution Upgrading from Cisco MDS SAN-OS Release 2.1(1b) or earlier to Release 2.1.2 or later can disrupt traffic on any SSM installed on your MDS switch

Upgrading a Switch with Insufficient Space for Two Images on the Bootflash

To upgrade the SAN-OS image on a Cisco MDS 9000 Family switch requires enough space on the internal CompactFlash (also referred to as bootflash) to accommodate both the old software image and the new software image.

As of Cisco MDS SAN-OS Release 3.1(1), on MDS switches with a 256-MB CompactFlash, it is possible in some scenarios that a user might be unable to fit two images on the bootflash. This lack of space on the bootflash might cause the upgrade process to fail because new images are always copied onto the bootflash during an upgrade.

The following MDS switches are affected by this issue:

MDS 9216 and MDS 9216i

MDS 9120 and MDS 9140

MDS 9500 Series switches with a Supervisor 1 module

To work around an image upgrade failure caused by a lack of space on the bootflash, follow these steps:


Step 1 Prior to installing the new image, copy the old (existing) system image file to an external server. You may need to reinstall this file later.

Step 2 Delete the old system image file from the bootflash by using either the Fabric Manager install utility or the CLI delete bootflash: command. The system image file does not contain the word "kickstart" in the filename.
switch# delete bootflash:m9200-ek9-mz.3.0.3.bin


Note On MDS 9500 Series switches, you also need to delete the image file from the standby supervisor after deleting it from the active supervisor.
switch# delete bootflash://sup-standby/m9500-sf1ek9-mz.3.0.3.bin


Step 3 Start the image upgrade or installation process using the Fabric Manager install utility or the CLI install all command.

Step 4 If the new installation or upgrade fails while copying the image and you want to keep the old (existing) image, then copy the old image (that you saved to an external server in Step 1) to the bootflash using either Fabric Manager or the copy command.

Step 5 If the switch fails to boot, then follow the recovery procedure described in the "Troubleshooting Installs, Upgrades, and Reboots" section of the Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x.


Upgrading a Cisco MDS 9124 Switch

If you are upgrading from Cisco MDS SAN-OS Release 3.1(1) to Cisco SAN-OS Release 3.3(3) on a Cisco MDS 9124 Switch, follow these guidelines:

During the upgrade, configuration is not allowed and the fabric is expected to be stable.

The Fabric Shortest Path First (FSPF) timers must be configured to the default value of 20 seconds; otherwise, the nondisruptive upgrade is blocked to ensure that the maximum down time for the control plane can be 80 seconds.

If there are any CFS commits in the fabric, the nondisruptive upgrade will fail.

If there is a zone server merge in progress in the fabric, the nondisruptive upgrade will fail.

If a service terminates the nondisruptive upgrade, the show install all failure-reason command can display the reason that the nondisruptive upgrade cannot proceed.

If there is not enough memory in the system to load the new images, the upgrade will be made disruptive due to insufficient resources and the user will be notified in the compatibility table.

Performing a Disruptive Upgrade on a Single Supervisor MDS Family Switch

Cisco MDS SAN-OS software upgrades are disruptive on the following single supervisor Cisco MDS Family switches:

MDS 9120 switch

MDS 9140 switch

MDS 9216i switch

If you are performing an upgrade on one of those switches, you should follow the nondisruptive upgrade path shown in Table 7, even though the upgrade is disruptive. Following the nondisruptive upgrade path ensures that the binary startup configuration remains intact.

If you do not follow the upgrade path, (for example, you upgrade directly from SAN-OS Release 2.1(2) or earlier version to SAN-OS Release 3.3(3)), the binary startup configuration is deleted because it is not compatible with the new image, and the ASCII startup configuration file is applied when the switch comes up with the new upgraded image. When the ASCII startup configuration file is applied, there may be errors. Because of this, we recommend that you follow the nondisruptive upgrade path.

Upgrading an MDS 9222i Switch

If you are running SAN-OS Release 3.3(3) on an MDS 9222i switch and you want to upgrade to an NX-OS 4.x release, you can upgrade to release 4.1(3a) and higher. Do not attempt to upgrade an MDS 9222i switch from SAN-OS 3.3(3) to NX-OS 4.1(1x) (including 4.1(1b) and 4.1(1c)) because the upgrade path is not supported on the MDS 9222i. This restriction does not apply to other platforms.

Before upgrading, issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.

Following the upgrade, you may need to enable features with the feature feature-name command, such as the feature iscsi command. In SAN-OS 3.3(x) release, features are enabled with the feature-name enable command, such as the iscsi enable command.

Downgrading Your Cisco MDS SAN-OS Software Image

This section lists the guidelines recommended for downgrading your Cisco MDS SAN-OS software image and contains the following sections:

General Downgrading Guidelines

FICON Downgrade Paths

Downgrading the SSI Image on Your SSM

Downgrading an MDS 9222i Switch

General Downgrading Guidelines

Use the following guidelines to nondisruptively downgrade your Cisco MDS SAN-OS Release 3.3(3):

Install and configure dual supervisor modules.

Issue the system no acl-adjacency-sharing execute command to disable acl adjacency usage on Generation 2 and Generation 1 modules. If this command fails, reduce the number of zones, IVR zones, TE ports, or a combination of these in the system and issue the command again.

Disable all features not supported by the downgrade release. Use the show incompatibility system downgrade-image CLI command to determine what you need to disable.

Layer 2 switching traffic is not disrupted when downgrading to Cisco SAN-OS Release 2.1(2) or later.

Use the show install all impact downgrade-image CLI command to determine if your downgrade will be nondisruptive.

Be aware that some features impact whether a downgrade is disruptive or nondisruptive:

Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively downgraded. See Table 9 for the nondisruptive downgrade path for all SAN-OS releases.

SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write acceleration, is disrupted during a downgrade. SSM Fibre Channel traffic is not.

Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during a downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MPS-14/2 module, the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the downgrade is in progress.

iSCSI: If you are downgrading from SAN-OS version 3.0(x) to a lower version of SAN-OS, enable iSCSI if an IPS module, MPS-14/2 module, MSM-18/4 module, or the MDS 9222i switch is online. Otherwise, the downgrade will disrupt traffic.

IVR: With IVR enabled, you must follow additional steps if you are downgrading from Cisco SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the "Upgrading with IVR Enabled" section for these instructions.

FICON: If you have FICON enabled, the downgrade path is different. See the "FICON Downgrade Paths" section.

Use Table 9 to determine the nondisruptive downgrade path from Cisco SAN-OS Release 3.3(3). Find the SAN-OS image you want to downgrade to in the To SAN-OS Release column of the table and use the path recommended.


Note The software downgrade information in Table 9 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and SSM intelligent services traffic.

FICON Downgrade Paths

Cisco MDS SAN-OS Release 3.3(3) does not support FICON.

Refer to Table 8 for a list SAN-OS and NX-OS releases that support FICON. Refer to the specific release notes for FICON downgrade path information.

Downgrading the SSI Image on Your SSM

Use the following guidelines when downgrading your SSI image on your SSM.

On a system with at least one SSM installed, the install all command might fail on an SSM when you downgrade from Cisco SAN-OS Release 3.3(3) to any SAN-OS 2.x release earlier than SAN-OS Release 2.1(2e). Power down the SSM and perform the downgrade. Bring up the SSM with the new bootvar set to the 2.x SSI image.

Downgrade the SSI boot images on the SSMs on the switch to a release version supported by your Cisco SAN-OS release. Refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage Service Interface Images.

SSM intelligent services traffic switching on SSM ports is disrupted on upgrades or downgrades.

Fibre Channel switching traffic on SSM ports is not disrupted under the following conditions:

All SSM applications are disabled. Use the show ssm provisioning command to determine if any applications are provisioned on the SSM. Use the no ssm enable feature configuration mode command to disable these features.

The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld command to determine your EPLD version. Refer to the Cisco MDS 9000 Family Release Notes for Cisco MDS 9000 EPLD Images to upgrade your EPLD image.

Refer to the Cisco Data Center Interoperability Support Matrix and the "Managing Modules" chapter in the Cisco MDS 9000 Family CLI Configuration Guide, Release 3.x, for information on downgrading your SSM.

Downgrading an MDS 9222i Switch

If you are running MDS NX-OS 4.1(1x) on an MDS 9222i switch and you need to downgrade to a SAN-OS 3.3(x) release, you can downgrade to Release 3.3(2), 3.3(1c), or 3.3(1a), but you cannot downgrade to 3.3(3). A nondisruptive downgrade from NX-OS 4.1(1x) to SAN-OS 3.3(3) is not supported on the MDS 9222i switch. This restriction does not apply to other platforms.

Before downgrading, disable all features not supported by the downgrade release. Use the show incompatibility system downgrade-image CLI command to determine what features you need to disable.

Following the downgrade, you will need to enable features with the feature-name enable command, such as the iscsi enable command. In NX-OS 4.1(x) releases, features are enabled with the feature feature-name command, such as the feature iscsi command.

New Features in Cisco MDS SAN-OS Release 3.3(3)

Upgrading to Recover Loss of Performance Manager Data


Caution You must upgrade to Fabric Manager Release 3.1(x) and then upgrade to a later release of Fabric Manager to avoid losing Performance Manager data. If data has been lost, follow the steps below to recover the data.


Step 1 Disable Performance Manager interpolation using Fabric Manager Web Client. Uncheck Interpolate missing statistics, then click Apply.

Step 2 Stop the Fabric Manager Server.

Step 3 Save the data file in the $INSTALL_DIR directory.

Step 4 Move the old RRD file into the $INSTALL_DIR/pm/db directory.

Step 5 Run $INSTALL_DIR/bin/pm.bat m.

Step 6 Restart Fabric Manager Server.


Maximum Number of Zones Supported in Interop Mode 4

In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to limitations in the connected vendor switch.

When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones, in the active zone set is 2047.

Upgrading the SAN-OS Software on the MDS 9222i Switch

On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1a), or Release 3.3(1c) to SAN-OS Release 3.3(3) fails when there is an active FC-Redirect configuration (created by Cisco SME or Cisco DMM applications) on the switch. An active FC-Redirect configuration is defined as:

FC-Redirect configuration for hosts or target connected locally

FC-Redirect configuration created by application running on that switch.

If an upgrade is attempted when an active configurations is present, the switch will go into a disruptive upgrade.

Java Web Start

When using Java Web Start, it is recommended that you do not use an HTML cache or proxy server. You can use the Java Web Start Preferences panel to view or edit the proxy configuration. To do this, launch the Application Manager, either by clicking the desktop icon (Microsoft Windows), or type ./javaws in the Java Web Start installation directory (Solaris Operating Environment and Linux), and then select Edit>Preferences.

If you fail to change these settings, you may encounter installation issues regarding a version mismatch. If this occurs, you should clear your Java cache and retry.

Deleting Cisco SME Interfaces

A Cisco SME interface can be deleted from the cluster only after the interface is administratively shut-down and all related tasks associated with the interface shut-down are complete.

Emulex Driver Version

In some instances, the Emulex driver version 8.1.10.9 may set the task attribute to HEAD_OF_QUEUE instead of SIMPLE_QUEUE. Certain tape drives do not accept this attribute and may reject these commands. The Emulex driver version 8.1.10.12 does not have this issue.

Cisco MDS 9222i Module Upgrade

On the MDS 9222i module, an upgrade from SAN-OS Release 3.2(x) to Release 3.3(1c) is not supported if there is a Cisco SME or Cisco DMM configuration in the fabric for hosts and targets attached to the MDS 9222i module.

SANTap

The SANTap feature allows third party data storage applications, such as long distance replication and continuous backup, to be integrated into the SAN.

Deleting SANTap Configurations Is Required Before Downgrade

If you are running Cisco MDS NX-OS Release 4.1(1b) in combination with the SSI 4.1(1b) image and you wish to downgrade to Cisco SAN-OS Release 3.3(3) and an SSI 3.2(3*) image, you must delete all SANTap configurations prior to the downgrade. Downgrading without completely deleting the SANTap configurations is not supported.

FCIP Interoperability

FCIP interoperability fails between two MDS switches, one running MDS NX-OS Release 4.1(1c) and the other running MDS SAN-OS Release 3.3(3), if the IP ACL configuration for an IPSec crypto map specifies TCP as the protocol, as in the following example:

switch(config)# ip access-list acl-name permit tcp local-gige-ip-address local-mask 
remote-gige-ipaddress remote-mask

FCIP interoperability does not fail if the IP ACL uses IP as the protocol, as in the following example:

switch(config)# ip access-list acl-name permit ip local-gige-ip-address local-mask 
remote-gige-ipaddress remote-mask

Applying Zone Configurations to VSAN 1

In the setup script, you can configure system default values for the default-zone to be permit or deny, and you can configure default values for the zone distribution method and for the zone mode.

These default settings are applied when a VSAN is created. However, the settings will not take effect on VSAN 1, because it exists prior to running the setup script. Therefore, when you need these settings for VSAN 1, you must explicitly issue the following commands:

zone default-zone permit vsan 1

zoneset distribute full vsan 1

zone mode enhanced vsan 1

Running Storage Applications on the MSM-18/4

The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time.

Compatibility of Fabric Manager and Data Mobility Manager

Cisco Fabric Manager in any MDS NX-OS 4.1(x) release does not support Data Mobility Manager (DMM) in any SAN-OS 3.3(x) release or in any 3.2(x) release. To use the Cisco Fabric Manager GUI for DMM, both Fabric Manager and DMM must be running NX-OS or SAN-OS software from the same release series.

Limited ISSU Support on the MDS 9222i Switch

An in-service software upgrade (ISSU) from SAN-OS Release 3.3(3) to NX-OS Release 4.1(1b) or to NX-OS Release 4.1(1c) is not supported on the MDS 9222i switch. This limitation applies only to the MDS 9222i switch. You can perform an ISSU from SAN-OS Release 3.3(3) to NX-OS Release 4.1(1b) or NX-OS Release 4.1(1c) on other MDS switches.

ISSU upgrades from SAN-OS Release 3.3(3) to NX-OS Release 4.1(3a) and to NX-OS Release 4.13(a) are supported on the MDS 9222i switch.

PPRC Not Supported with FCIP Write Acceleration

IBM Peer to Peer Remote Copy (PPRC) is not supported with FCIP Write Acceleration.

Using IVR In a Fabric With Mixed Code Versions

If you are using IVR and you are running SAN-OS 3.x software on your MDS switches, make sure that all IVR switches run the same code version. Otherwise, if you have a fabric with mixed code versions, the switches running the higher version may not be able to see all IVR devices. The mixed fabric can cause an inconsistent database among IVR switches, which might affect IVR behavior. For this reason, it is important that all IVR switches run the same SAN-OS version, preferably SAN-OS Release 3.3(4a), which has device update (DU) support, or later.

HTTP Transport Method Not Supported in Call Home

Cisco SAN-OS Release 3.x does not support the HTTP transport method in the Call Home feature.

Resolved Caveats

CSCsc17059

Symptom: In rare circumstances, after upgrading the SAN-OS, a Generation 1 module may be rebooted as it stops responding to the keep alive messages from the Supervisor module.

Workaround: This issue is resolved.

CSCsg49151

Symptom: If you bring up more than one link at a time between two VSANs that have overlapping domains and at least one of the switches is SDV enabled, one link will become isolated. The other links will come up, even though the domains are overlapping. In addition, the SDV virtual domains will change, causing traffic disruption on all devices associated with their old value.

Workaround: This issue is resolved.

CSCsi72048

Symptom: FCIP links may fail on an MDS 9216i switch that has compression set to auto when the other end of the FCIP link is terminated by an IPS-8 module. You may see the following message in the logs:

%IPS_SB_MGR-SLOT1-3-CRYPTO_FAILURE: Heartbeat failure in encryption engine (error 0x1)
%ETHPORT-5-IF_DOWN_SOFTWARE_FAILURE: Interface GigabitEthernet1/1 is down (Port software failure)
%PORT-5-IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip99 is down (Port software failure)

Workaround: This issue is resolved.

CSCsk49029

Symptom: If there is a request to export a domain while the same domain is being cleaned up, domain entries might not be programmed. As a result, communication between IVR devices might not occur.

Workaround: This issue is resolved.

CSCsk49634

Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently high loss rate.

Workaround: This issue is resolved.

CSCsk51193

Symptom: Following an upgrade to Cisco MDS SAN-OS Release 3.2(1) on a Cisco MDS 9124 switch, an interface is shown as up, but there is no FLOGI information for the port in the FLOGI database.

Workaround: This issues is resolved.

CSCsl39215

Symptom: The CIM server stops. This occurs after creating a subscription using the same filter and handler.

Workaround: This issue is resolved.

CSCso28570

Symptom: On the MDS 9222i module, an upgrade from SAN-OS Release 3.2(x) to Release 3.3(1a) fails when there is an active FC-Redirect configuration (created by Cisco SME or Cisco DMM applications) on the switch. An active FC-Redirect configuration is defined as:

FC-Redirect configuration for hosts or target connected locally

FC-Redirect configuration created by application running on that switch.

If an upgrade is attempted when such active configuration is present, the switch will go into a disruptive upgrade.

Workaround: This issue is resolved.

CSCso41087

Symptom: If FCIP is enabled and the SAN-OS is upgraded, the SNMP service will run into exception and the following syslog message is displayed: SNMP Operation(165) failed (62) setting error index.

Workaround: This issue is resolved.

CSCsq29607

Symptom: After logging back into Fabric Manager Client, clicking on the Summary tab causes a disconnect.

Workaround: This issue is resolved..

CSCsq44360

Symptom: When the startup rising alarm is triggered, the sample value is smaller than the rising threshold. This should not trigger an alarm.

Workaround: This issue is resolved.

CSCsr22782

Symptom: On Solaris 8, 9, and 10 and RedHat Linux AS4 (kernel version 2.6) the Fabric Manager Release 3.4(1) installer displays a warning message indicating that it is an unsupported platform. This occurs even though these platforms are supported.

Workaround: This issue is resolved.

CSCsr89410

Symptom: An FCIP link may flap due to a watchdog timeout condition when FCIP Tape Acceleration is running inSAN-OS Release 3.3(1c).

Workaround: This issue is resolved.

CSCsr92585

Symptom: An FCIP link running with Tape Acceleration may flap when the host is attempting SRR/REC tape error handling.

Workaround: This issue is resolved.

CSCsu38485

Symptom: When you enter the install ssi command, bootvar fails to synchronize between the active and standby supervisor.

Workaround: After the install ssi command executes, verify that the SSI bootvar on the standby supervisor is set to the new SSI image. Enter the show boot command to display the bootvar configuration. If the SSI bootvar is not set to the proper SSI image, then use the boot ssi <uri> command to configure the SSI bootvar on the active supervisor again and verify.

CSCsz84411

Symptom: An MDS 9124 switch may randomly reboot with a reset reason of unknown. This is a rare event and occurs only in systems that have a single power supply with a serial number beginning with QCS.

Workaround: Install and power up the redundant power supply.

CSCtb28442

Symptom: End of sequence is not set for STK drives when the host requests more data than what is written to the tape.

Workaround: None.

CSCtb77695

Symptom: When a tape reaches its capacity, an IBM TS1120 tape drive send a check condition with eom=1 and asc_ascq = 0. Because asc_ascq is not set to End of Medium or Partition, SME continues to send traffic as if the end of the tape has not been reached. As a result, the backup fails when it spans across multiple tapes. This issue is specific only to IBM TS1120 tape drives.

Workaround: None.

CSCtc20849

Symptom: Following a reboot of an MDS 9513 switch running Cisco SAN-OS Release 3.3(2), both supervisor modules generated core files. The show cores command and the show system reset-reason command displayed the following output:

switch# show cores
Module-num       Process-name      PID     Core-create-time
----------       ------------      ---     ----------------
8                qos               15671   Sep 21 22:16
7                qos               4370    Sep 21 22:17
switch# show system reset-reason
----- reset reason for Supervisor-module 8 (from Supervisor in slot 8) ---
1) At 517868 usecs after Mon Sep 21 22:12:09 2009
    Reason: Reset triggered due to HA policy of Reset
    Service: Service "qos"
    Version: 3.3(2)
----- reset reason for Supervisor-module 7 (from Supervisor in slot 7) ---
1) At 260648 usecs after Mon Sep 21 22:12:37 2009
    Reason: Reset triggered due to HA policy of Reset
    Service: Service "qos"
    Version: 3.3(2)

Workaround: To mitigate the risk of a QoS failure, configure static persistent FC IDs so that the local logins do not share the same domain or area. There should be no more than 50 logins with the same area.

In addition, you can enter the show qos internal mem-stats detail | inc fcid command and then check the current allocation value of the QOS_MEM_qos_fcid in the output. If this value is close to 70000, then there is a high chance of a QoS failure, followed by a system reboot.

CSCsw95386

Symptom: Certain applications that use SME perform a move medium operation to change tapes in a library, without first performing a load or unload operation. This causes the check condition "SCSI check condition of medium may have changed." SME does not perform the media identification logic correctly for this check condition, which causes tape labeling to fail

Workaround: This issue is resolved.

CSCse31881

Symptom: If there are IP over Fibre Channel (IPFC) interfaces configured on an SSM, you might experience issues if you downgrade from SAN-OS Release 3.x to Release 2.x.

Workaround: This issue is resolved.

CSCsg19148

Symptom: Time zone changes that are executed on an MDS switch do not take effect on the 12-port, 24-port, and 48 port 1-Gbps/2-Gbps/4-Gbps Fibre Channel modules, and on the 4-port 10-Gbps module. This issue occurs in SAN-OS Releases 3.0(1), 3.0(2), 3.0(2a), and 3.0(3).

Time zone changes that are executed on an MDS switch do not take effect on the 16-port or 32-port 1-Gbps/2-Gbps module, on the 4-port or 8-port Gigabit Ethernet IP services module, the MPS-14/2 module, and on the SSM. This issue occurs in SAN-OS Release 3.0(3).

This issue has no effect on functionality. However, debug messages and syslogs from the MDS switching modules have incorrect timestamps if the time zone is configured on an MDS switch.

Workaround: This issue is resolved.

CSCsg19303

Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.

Workaround: This issue is resolved.

CSCsk35951

Symptom: In a configuration with a PortChannel with FCIP members and write acceleration in use, if IVR NAT is enabled on one end of the PortChannel and not enabled on the other end, then traffic over the FCIP tunnel might fail.

Workaround: This issue is resolved.

CSCsk63929

Symptom: If DMM is provisioned on the SSM and you downgrade to a Cisco MDS SAN-OS release that does not support DMM, the configuration persists and the GUI and CLI show DMM as a provisioned application.

Workaround: This issue is resolved.

CSCsk87502

Symptom: If an NASB configuration in a VSAN is destroyed while a target discovery is pending, the NASB process fails. Issue the show nasb vsan x command on the SSM to view the target discovery in the Pending state.

Workaround: This issue is resolved.

CSCsk93834

Symptom: In rare situations during a storage-based online data migration job, the user might not be able to destroy the job if the following sequence of events occurs:

1. A storage-based data migration job is executing.

2. A port flap occurs on the server and the server HBA port goes down.

3. The storage-based data migration job continues executing until it completes.

4. The user issues the dmm module module-id job job-id destroy command to delete the storage-based data migration job, but the delete fails.

Workaround: This issue is resolved.

CSCsk95241

Symptom: If you use JDK instead of JRE on Solaris, you might encounter a problem trying to install Device Manager from a web browser. This can happen because the installer heap limit of 256 MB is not sufficient.

Workaround: This issue is resolved.

CSCsl15511

Symptom: On the MDS 12-port, 24-port, and 48-port 4-Gbps Fibre Channel switching modules, and on the 4-port 10-Gbps Fibre Channel switching module for downgrades from 3.2(2c) to lower versions, if fcdomain persistency is disabled, F ports may not come up after a shutdown or no shutdown or a link flap.

Workaround: This issue is resolved.

CSCsl17944

Symptom: During an MDS 9222i switch reload, the connection from the management port (mgmt0) to the Gigabit Ethernet interface goes down. When the connection comes back up, the Gigabit Ethernet interface doesn't go into forwarding mode until 30 seconds later. The Fabric Manager server is not able to communicate to the MDS 9222i switch through SNMP during this 30 second window.

Workaround: This issue is resolved.

CSCsl31087

Symptom: In DMM, if a server I/O to a LUN fails during data migration, that session is marked as failed. The DMM migration job is then moved to a Failed state when the remaining sessions are complete. Such a failed migration job can be scheduled for a restart. If such a failed migration job is scheduled to start in less than 5 minutes from the time of scheduling, and another server I/O to a session LUN fails in that 5 minute window, the migration job will move from a Scheduled state to a Failed state. An administrator has the option to start the job immediately or schedule it again. This problem does not happen if an administrator schedules the migration job to start more than 5 minutes from the time of scheduling.

Workaround: This issue is resolved.

CSCsl34922

Symptom: Dual-fabric DMM migration jobs can not have one fabric running Release 3.2(1a) and a peer fabric running Release 3.2(2c) due to a signal message change. This may cause unexpected results during a DMM migration job validation, creation, start, and so on.

Workaround: This issue is resolved.

CSCsl42571

Symptom: SNMP timeouts occur when a AAA user ages out.

By design, a AAA user is aged out every hour on a switch for security reasons. If a large fabric is discovered using a AAA user and a Performance Monitoring (PM) collection is added for such a fabric, a number of SNMP requests (related to the discovery or PM statistics collection) could time out. When a user views the PM statistics charts (in the Performance tab in the web client), the charts are not seen as continuous.

Workaround: This issue is resolved.

CSCsl65951

Symptom: Using Fabric Manager Release 3.2(2), an error is displayed in the creation wizard. This occurs when an enclosure spans multiple fabrics and not all fabrics are managed and when the Data Migration Wizard is used to create a job with that enclosure as the existing storage (selecting all ports listed in that enclosure).

Workaround: This issue is resolved.

CSCsm08837

Symptom: When an IVR-enabled MDS switch with an empty device alias database, attempts to join a fabric which has approximately 7000 device aliases, the device alias merge fails. In this situation, the following occurs:

During the merge process between local and remote switches, the remote device alias database is received on the local switch. The local switch validates those device aliases with SAP 110 (which is IVR).

Since all 7000 aliases could not be sent in a single MTS message, the aliases are fragmented into 5 messages.

While IVR requires approximately 20 seconds to process each fragment, effectively it takes around 100 seconds to process all 5 messages.

Because DDAS has a timeout of around 60 seconds, the merge is rejected.

The merge process is retried after few minutes and the process repeats. Then finally failed.

Workaround: This issue is resolved.

CSCsm54071

Symptom: Data Virtual Targets (DVTs) are lost after a downgrade from Release 3.3(1x) to earlier releases.

Workaround: This issue is resolved.

CSCsm94323

Symptom: When a PortChannel is created between 2 switches using the PortChannel wizard in Fabric Manager, the map might not immediately update and may not show the ISLs as part of the PortChannel. After a few discovery cycles, if the map is not updated, then the ISLs may be displayed along with the PortChannel in the map.

Workaround: This issue is resolved.

CSCso05448

Symptom: FCIP links might fail to come up after a module reload following a hardware failure on the module.

Workaround: This issue is resolved.

CSCso55622

Symptom: In Microsoft Windows 2000, 2003, 2003 R2, and 2008, when installing Fabric Manager, Fabric Manager Server, and Device Manager, a service may not restart and/or may not properly execute the PostgreSQL installer. This may lead to an incorrect conversion of the PostgreSQL database and/or the service may not start. This occurs when running Microsoft Windows 2000, 2003, 2003 R2, or 2008 with Terminal Server running in Application mode.


Note This applies only to Terminal Server running in Application Mode. This issue does not affect users running a Terminal Server or Remote Desktop session in Remote Administration mode.


Workaround: This issue is resolved.

CSCso63465

Symptom: FCP-CMD (for example, Inquiry) frames targeted to LUN 0x45F0 or LUN 0x50F0 are dropped by an MDS switch when traffic flows (egresses) through Generation 2 modules. LUN 0x45F0 corresponds to HPUX Volume Set Address <VBUS ID: 0xB, Target ID: 0xE, LUN: 0x0>.

Workaround: This issue is resolved.

CSCsq54455

Symptom: On a DS-X9032 module where the SRAM parity error was seen, the SRAM parity error exceptions were logged continuously.

Workaround: This issue is resolved.

CSCsq57352

Symptom: After upgrading from Fabric Manager Release 3.0(2a) to Fabric Manager Release 3.2(3a), the Fabric Manager client fails to reuse the map layout files produced by Release 3.0(2a). Renaming the map layout files will make them compatible with Fabric Manager Release 3.2(3a).

Workaround: This issue is resolved.

CSCsq66823

Symptom: On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1a), or Release 3.3(1c) to SAN-OS Release 3.3(1c) fails when there is an active FC-Redirect configuration (created by SME or DMM applications) on the switch. An active FC-Redirect configuration is defined as:

FC-Redirect configuration for hosts or targets connected locally

FC-Redirect configuration created by the application running on that switch.

If an upgrade is attempted when an active configurations is present, the switch will go into a disruptive upgrade.

Workaround: This issue is resolved.

CSCsr90831

Workaround: This issue is resolved.

CSCsw78035

Symptom: When FlexAttach is enabled on the switch, the physical pWWN in the FCNS registration response is not rewritten with the virtual pWWN.

Workaround: This issue is resolved.

CSCsy16228

Symptom: Standard variables and user-defined variables are not being substituted in scripts, scheduler jobs, and the CLI.

Workaround: This issue is resolved.

CSCso31754

Symptom: IVR does not finish a domain capture which stops the export of IVR devices.

Workaround: This issue is resolved.

CSCsk91974

Symptom: When you issue the show tech-support sme or the show klm internal isapi_scsi command after attaching to a module, you may see this error message: cat: write error: Bad address. This issue does not affect the actual tech-support log.

Workaround: This issue is resolved.

CSCsk73654

Symptom: In certain tape libraries, the tape drives are exported as LUNs. If these target ports are already a part of a Cisco SME configuration and new tape drives are added as LUNs, the new tape drives will not be discovered during a Cisco SME tape group or tape device configuration.

Workaround: This issue is resolved.

CSCso50663

Symptom: The following syslog message is displayed:

%SME_CPP-SLOT13-3-LOG_ERR_SME_ITL_CPP_ERR: Module:13 Host-Target IT Nexus I:0xc1f3202015180006 T:0xc5a0202000010006 vsan:3000 oid:0x117 LunID:0x0000.

This message is for debugging purposes and is also displayed during the upgrade of an MSM-18/4 module. An upgrade of the MSM-18/4 module where Cisco SME is enabled, is disruptive; however, this syslog message does not indicate an issue.

Workaround: This issue is resolved.

CSCsm13002

Symptom: In rare cases, if a READ command issued by Cisco SME for media identification is dropped or lost, the tape is marked as a clear-text tape. Subsequently, a CHECK_CONDITION with ILI is returned when a READ is issued by the host. This can cause a backup application to mark the tape as read-only.

Workaround: This issue is resolved.

Open Caveats

CSCsv66455

Symptom: The management port hangs and does not transmit packets. The following syslog message displays: eth1: tx timeout.

Workaround: Flap the management port or perform a supervisor switchover.

CSCsl71227

Symptom: Using Fabric Manager Release 3.2(2), if you have an enclosure with multiple ports and you then use the Data Migration Wizard to create a job with that enclosure as the existing storage but don't select all the storage ports in the enclosure, an error is displayed in the creation wizard.

Workaround: Put the ports you plan to use as the existing storage in the migration into a separate enclosure, and use that enclosure in the wizard selection.

CSCso19341

Symptom: Under very rare circumstances, the ports on an MDS 9000 24-port 4-Gbps Fibre Channel module and on an MDS 9000 48-port 4-Gbps Fibre Channel module might fail and the state of the ports might change to hwFailure, or the module might reload when all the ports on the module fail.

If this occurs, the output of the show logging log command will be similar to the following:

2008 Mar 12 09:36:47 sw-DC3-Core-9509-1 %PORT-5-IF_DOWN_LINK_FAILURE: %$VSAN 2420%$ 
Interface fc3/2 is down (Link failure)

re Channel) due to Stratosphere common module experienced an error in device 63 (error 
0xc3f00276)

Or, the output of the show logging log command will be similar to the following:

%MODULE-2-MOD_DIAG_FAIL: Module 1 (serial: JABxxxxxxxx) reported failure on ports 
1/1-1/24 (Fibre Channel) due to Q-Engine experienced an internal hardware error in 
device 55 (device error 0xc3700637)
%MODULE-2-MOD_SOMEPORTS_FAILED: Module 1 (serial: JABxxxxxxxx) reported failure on 
ports 1/1-1/24 (Fibre Channel) due to Q-Engine experienced an internal hardware error 
in device 55 (error 0xc3700637)

The output of the show module internal exceptionlog command will be similar to the following:

********* Exception info for module 1 ********
exception information --- exception instance 1 ----
Module Slot Number: 1
Device Id         : 55
Device Name       : Tuscany-que
Device Errorcode  : 0xc3700637
Device ID         : 55 (0x37)
Device Instance   : 00 (0x00)

ErrNum (devInfo)  : 55 (0x37)
System Errorcode  : 0x40420032 Q-Engine experienced an internal hardware error
Error Type        : Minor error

Workaround: None.

CSCtc48338

Symptom: On any of the MDS 9500 Series Director switches that have removable Supervisor 2 modules, a supervisor may reset when any one of the following commands is executed on the switch, or the same information is collected through Cisco Fabric Manager or Device Manager:

show hardware internal mgmt0 stats

show hardware internal eobc stats

show tech

show tech details

show tech-support

tac-pac

In a dual supervisor switch, entering one of these commands will force a supervisor switchover. In single supervisor systems, the switch will reload.

This issue does not affect switches with a nonremovable Supervisor 2 module, such as the MDS 9222i or MDS 9124.

Workaround: There are three ways that you can work around this issue:

Do not enter the show hardware internal mgmt0 stats command or the show hardware internal eobc stats command.

Upgrade to one of the following software releases when it becomes available:

Cisco SAN-OS Release 3.3(4a) or above

Cisco NX-OS Release 4.2(3) or above

Before running the show tech-support command, the show tech-support details command, or the tacpac command from the CLI or from Cisco Fabric Manager or Device manager, download a plug-in from the Software Download Center to patch the commands. Load the plug-in on the active and standby supervisor as described in the following steps. The plug-in is not persistent across switchovers and should be loaded any time a switchover occurs.

To download and install the plug-in, follow these steps:

1. Download the plug-in from http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=282764109

2. Select release 1.0.

3. Make a copy of the downloaded gplug by entering the following command:
switch# copy bootflash:m9500-sup2-showtech-FN63288-plugin-1.0.bin bootflash:gplug_copy

4. Copy the copy of the gplug to the standby supervisor by entering the following command:
switch# copy bootflash:gplug_copy bootflash://sup-remote/

5. Load the gplug on the active supervisor by entering the following command:
switch# load bootflash:gplug_copy

6. Attach to the standby supervisor by entering the following command:
switch# attach module <standby-sup-slot>

7. Load the gplug onthe standby supervisor by entering the following command:
switch# load bootflash:gplug_copy

Customer: http://www.cisco.com/en/US/customer/ts/fn/632/fn63288.html

CSCsk35725

Symptom: Fabric Manager takes 2 to 3 minutes to bring up the DMM job creation wizard in a setup with 25 switches, 400 enclosures, and 2400 entries in the name server.

Workaround: None.

CSCso49196

Symptom: During an upgrade from SAN-OS Release 3.2(3a) to Release 3.3(1a), when a switchover occurs to the Supervisor running Release 3.3(1a), Cisco SME traffic flows for hosts that are not connected locally to the switch that is getting upgraded, may get flapped for a very short time. This can also occur during a switchover to a Supervisor running Release 3.3(1a).

Workaround: None.

CSCsq20408

Symptom: After creating SANTap Control Virtual Targets (CVTs) or SANTap Data Virtual Targets (DVTs), the running-configuration and the startup-configuration are not synchronized. Output from the show startup-config command will be different from the output of the show running-config and the startup configuration will not display SANTap configuration information.

Workaround: Issue the copy running-startup command whenever you create SANTap Control Virtual Targets (CVTs) or SANTap Data Virtual Targets (DVTs) so that the running configuration and the startup configuration are synchronized.

CSCsr85709

Symptom: Under certain conditions, the port manager can take a long time to respond to a port configuration, which can trigger a set-port-configuration failure. If this occurs, then the FCIP tunnel will not come up and will stay in a disabled state.

Workaround: Enter a shut command, followed by a no shut command on the FCIP interface at either end of the FCIP tunnel.

CSCsy37212

Symptom: Under rare conditions, a port may drop data after the port flaps in the presence of congestion. The output of the show hardware internal packet-flow dropped command shows the dropped data as RX (receive) frame drops on a module. In such instances, the following type 1, type 2, and possibly type 3 errors may be seen:

Type 1 errors are internal ASIC parser CRC errors.

Type 2 errors are internal ASIC overflow or ECC parity errors.

Type 3 errors may occur when ports on a DS-X9124 or DS-X9148 module are put into a hardware failure state by the software. If all ports fail in this fashion, then the software reloads the module. If only some of the ports fail, the module is not reloaded.

For this issue to occur, the port must have frames held in the port buffer at the time that the port is brought down and up. A port normally has time to empty its buffers when it is shut down. However, in unusual cases, such as if there is congestion on the port at the time of the shutdown, or in rare cases, frames can still be held in the buffers while the port is reinitialized.

Workaround: None. If you experience this issue, check the fabric for congestion andthen remove the congestion. Reload the module to recover ports that are in a hardware failure state.

CSCsz01738

Symptom: A host that is behind a NPIV F port cannot see the zoned LUNs if the addition of the F port to the zone and the zone set activation occur after an In Service Software Upgrade (ISSU). This issue applies only to an NPIV F port on MDS 9124 and MDS 9134 fabric switches.

Workaround: Following the ISSU, enter the shut command followed by the no shut command on the NPIV F port, and then activate the zone set.

CSCsk43927

Symptom: The following Fabric Manager client components that use SSH and Telnet do not work well with NAT:

DMM storage job creation

Cisco SAN-OS software upgrade

Zone activation

Workaround: None.
