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
•
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 rolling2 yes disruptive rolling Hitless upgrade is not supported3 yes disruptive rolling Hitless upgrade is not supported4 yes non-disruptive rolling5 yes non-disruptive reset6 yes non-disruptive resetAt 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.

If you would like to request a copy of the source code under the terms of either GPL or LGPL, please send an e-mail to mds-software-disclosure@cisco.com.
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.
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.
Table 4 Software Images for MDS 9200 Series Switches
Switch ImageMDS 9222i
Filename begins with m9200-s2ek9
MDS 9216A or MDS 9216i
Filename begins with m9200-ek9
Selecting the Correct Software Image for an MDS 9500 Series Switch
The system and kickstart image that you use for an MDS 9500 Series switch depends on whether the switch is based on a Supervisor-1 module or a Supervisor-2 module, as shown in Table 5.
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 moduleMod Ports Module-Type Model Status--- ----- -------------------------------- ------------------ ------------......5 0 Supervisor/Fabric-1 DS-X9530-SF1-K9 active*6 0 Supervisor/Fabric-1 DS-X9530-SF1-K9 ha-standbyFor a Supervisor-2 module, the output might look like this:
switch# show moduleMod 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-standbyMigrating 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.
CautionMigrating 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:

Upgrading Your Cisco MDS SAN-OS Software Image
This section lists the guidelines recommended for upgrading your Cisco MDS SAN-OS software image and contains the following sections:
•
Performing a Nondisruptive Software Upgrade on Generation 1 Modules
•
Upgrading Your Version of Cisco Fabric Manager
•
Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.2(3)
•
Upgrading the SSI Image on Your SSM
•
Upgrading a Switch with Insufficient Space for Two Images on the Bootflash
•
Upgrading a Cisco MDS 9124 Switch
•
Performing a Disruptive Upgrade on a Single Supervisor MDS Family Switch
Performing a Nondisruptive Software Upgrade on Generation 1 Modules
Generation 1 modules may reload during a nondisruptive SAN-OS software upgrade because of the CompactFlash being unable to partition for the new code. If that happens, the installer aborts and reloads the module.
This issue affects the following modules:
•
DS-X9016, 16-port 1-Gbps/2-Gbps Fibre Channel module
•
DS-X9032, 32-port 1-Gbps/2-Gbps Fibre Channel module
•
DS-X9032-SSM, 32-port 1-Gbps/2-Gbps Fibre Channel Storage Services Module (SSM)
•
DS-X9302-14K9, 14-port Fibre Channel/2-port Gigabit Ethernet Multiprotocol Services (MPS-14/2) module
This issue might be seen during an upgrade from Cisco SAN-OS Release 3.0(x), 3.1(x) or 3.2(x). It has been addressed for upgrades from SAN-OS Release 3.3(1) or higher. Therefore, you will not be impacted by this issue if you are running SAN-OS Release 3.3(1) when you upgrade to a higher SAN-OS release.
When this problem occurs, the module will automatically reload and may cause the Install All to stop, which will cause the upgrade to be unsuccessful. Error messages similar to the following may be displayed:
Install has failed. Return code 0x40930020 (Non-disruptive upgrade of a module failed).Please identify the cause of the failure, and try 'install all' again.Module 2: Non-disruptive upgrading.-- FAIL. Return code 0x40690009 (Error in downloading image for image upgrade).To avoid this kind of unplanned disruption, follow the methods for identifying and correcting this issue described in Cisco Field Notice 63099, before proceeding with the SAN-OS upgrade. This Field notice can be found under the Support, Products page for Cisco MDS9500 Series Multilayer Directors selection.
The caveat associated with this issue is CSCsm62295.
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.

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.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.
Note
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.
4.
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.
5.
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
To install Fabric Manager on Solaris, follow these steps:
Step 1
Set Java 1.5 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-3.2.3.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-3.2.3.jar
Step 5
Follow the onscreen instructions provided in the Fabric Manager management software setup wizard.
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 3.2(3).
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.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.
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.
General Upgrading Guidelines
Use the following guidelines when upgrading to Cisco MDS SAN-OS Release 3.2(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 6 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 Table 7.
Use Table 6 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.2(3). Find the image release number you are currently using in the Current column of the table and use the path recommended.
Note
The software upgrade information in Table 6 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and SSM intelligent services traffic.
FICON Supported Releases and Upgrade Paths
Cisco MDS SAN-OS Release 3.2(3) does not support FICON.
Table 7 lists the SAN-OS and NX-OS releases that support FICON. Refer to the specific release notes for FICON upgrade path information.
Table 7 FICON Supported Releases
FICON Supported ReleasesNX-OS
Release 4.1(1c)
SAN-OS
Release 3.3(1c)
Release 3.2(2c)
Release 3.0(3b)
Release 3.0(3)
Release 3.0(2)
Release 2.0(2b)
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 3.2(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 interfaceport-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 databaseswitch(config-vsan-db)# vsan vsan-id suspendswitch(config-vsan-db)# no vsan vsan-id suspendStep 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 3.2(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 3.2(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 3.2(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 - 32fc2/1 is upHardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)Port WWN is 20:4b:00:0d:ec:09:3c:00Admin port mode is auto <-------- shows port is configured in auto modesnmp traps are enabledPort mode is F, FCID is 0xef0300 <-------- shows current port operational mode is FPort vsan is 1Speed is 2 GbpsTransmit B2B Credit is 3Step 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 tswitch(config)# interface fc 2/1switch(config-if)# switchport mode fxb.
Set the port admin mode to E if the current operational port mode is E:
switch# config tswitch(config)# interface fc 2/5switch(config-if)# switchport mode eStep 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 tswitch(config)# interface fc 2/2switch(config-if)# switchport mode fxb.
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 tswitch(config)# interface fc 2/2switch(config-if)# shutdownswitch# 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 SAN-OS Release Compatibility Matrix for Storage Service Interface Images.
–
All SSM applications are disabled. Use the show ssm provisioning CLI command to determine what applications are configured. Use the no ssm enable feature CLI command to disable these applications.
–
No SSM ports are in auto mode. See the "Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.2(3)" section.
–
The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld CLI 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 MDS Storage Services Module 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.
CautionUpgrading 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.binStep 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 3.2(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 6, 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 3.2(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.
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
•
Downgrading the SSI Image on Your SSM
General Downgrading Guidelines
Use the following guidelines to nondisruptively downgrade your Cisco MDS SAN-OS Release 3.2(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 8 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 Table 9.
Use Table 8 to determine the nondisruptive downgrade path from Cisco SAN-OS Release 3.2(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 8 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 3.2(3) does not support FICON.
Refer to Table 7 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 3.2(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 SAN-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 CLI command to determine if any applications are provisioned on the SSM. Use the no ssm enable feature configuration mode CLI command to disable these features.
–
The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld CLI 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 MDS Storage Services Module Interoperability Support Matrix and to the "Managing Modules" chapter in the Cisco MDS 9000 Family CLI Configuration Guide, Release 3.x for information on downgrading your SSM.

There are no new features available for this release.
Limitations and Restrictions
This section lists the limitations and restrictions for this release.
Upgrading to Recover Loss of Performance Manager Data
CautionYou 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.
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.
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.
Caveats
This section lists the open and resolved caveats for this release. Use Table 9 to determine the status of a particular caveat. In the table, "O" indicates an open caveat and "R" indicates a resolved caveat.

The chance of a module reload occurring again on the same module is very rare. Therefore, continued use of the module is acceptable.
A software workaround for this issue exists in SAN-OS Release 3.3.(2) and NX-OS Release 4.(1b). Upgrading to one of those releases will help decrease instances of modules reloads.
•
CSCsl66072
Symptom: During a hitless upgrade from SAN-OS Release 3.0(x) (or lower) to Release 3.1(x) (or higher), and a subsequent switchover or hitless upgrade, under certain runtime conditions, the Port-Channel Manager process (PCM) may terminate and potentially cause the switch to reboot. This issue occurs with MDS 95xx platforms only regardless of the supervisor version.
Workaround: This issue is resolved.
•
CSCsl72080
Symptom: ISLB zone set activation and zone set distribute fails. The reason is shown as "Duplicate Member". This issue occurs in the following conditions:
a.
When an active zone set is present in a VSAN and an ISLB zoneset activation is attempted.
b.
When zone set distribution is attempted in an IVR VSAN from Exec mode.
In SAN-OS Release 3.2.2 and Release 3.2.2x, the ISLB zone set activation and zone set distribution in an IVR VSAN are rejected by the zone server when an active zone set is present in a VSAN. The Duplicate Member message is displayed due to an incorrect validation. This issue has been resolved in SAN-OS Release 3.2.3 and later.
Workaround: This issue is resolved.
•
CSCsl75365
Symptom: Using the Fabric Manager Standalone version, the client stops after configuration changes are made.
Workaround: This issue is resolved.
•
CSCsl02669
Symptom: When an incorrect fabric identifier is assigned to a fabric during initial discovery, Performance Manager displays the wrong number of flows when fabrics are discovered at a later time.
Workaround: This issue is resolved.
•
CSCsl41090
Symptom: During an upgrade from SANOS Release 3.0(x) (or lower) to Release 3.2(1) (or higher), if you perform an SNMPWALK operation of the CISCO-ENTITY-SENSOR-MIB on the switch during the upgrade, the snmpd process may terminate resulting in the loss of the SNMP profile or similar consequences. In some cases, this may result in a switchover or a reboot.
Workaround: This issue is resolved.
•
CSCsl42923
Symptom: The VSAN filter summary stops polling.
Workaround: This issue is resolved.
•
CSCsl49158
Symptom: After a non-disruptive upgrade to SAN-OS's 3.0(1) thru Release 3.2(2c), traffic LEDs on Generation 2 Module (DS-X9704) do not blink.
Workaround: This issue is resolved.
•
CSCsl52998
Symptom: When the FCIP compression mode is set to mode2 or it is set to Auto and the maximum bandwidth configured for the FCIP profile is less than155Mbps, in rare cases (depending on the data pattern), there can be an FCIP link flap and the "Port Software Failure" error message is displayed.
Workaround: This issue is resolved.
•
CSCsl58537
Symptom: The CIM server does not authorize requests after an average of 25,000 requests. An unauthorized error is displayed.
Workaround: This issue is resolved.
•
CSCsl60060
SYMPTOM: With a device alias defined on an MDS switch and CFS is enabled for the device alias, and Fabric Manager shows fabric.fcalias=false, Fabric Manager does not populate the device alias to the host and target port table. A server discovery output shows a valid MDS switch as a device alias seed but there is no device alias.
The device alias database checksum persists in the Fabric Manager database, but the alias has not persisted yet, the fabric is closed or unmanaged. When the fabric is loaded and managed the next time and it is rediscovered, the checksum does not change so the rediscovering device alias is skipped.
Workaround: This issue is resolved.
•
CSCsl65913
Symptom: Using Fabric Manager Release 3.2(2), if you have an enclosure that spans multiple fabrics and not all the fabrics are managed and you then use the Data Migration Wizard to create a job with that enclosure as the existing storage (selecting all ports listed in that enclosure), an error is displayed in the creation wizard.
Workaround: This issue is resolved.
•
CSCsl51357
Symptom: The Device Manager Summary tab does not show multiple pWWNs that are on the NPV interface.
Workaround: This issue is resolved.
•
CSCsl55450
Symptom: The Fabric Manager Server GUI displays "Finished searching the table. The search item not found." This occurs when you select Inventory and then Zones to display the Member column, then click the Find icon (binoculars). In the resulting window, you type a word that is not on the first page and click 'find from start'. The main web page appears to refresh, but does not actually locate anything.
If you search for an item that is not on the first page, an error message displays "Finished searching the table. The Search item not found".
Workaround: None.
•
CSCsi43117
Symptom: CFS merge information does not include SNMP support.
Workaround: This will be included in a future Fabric Manager release.
Open Caveats
•
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: Bring up multiple links between two switches one at a time. Verify that the first link came up correctly before attempting to bring up the next link. If the first link fails to come up because of a domain ID overlap, resolve the domain conflict and then try again to bring up the links.
•
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: If both ends of an FCIP link are not on an MPS-14/2 module, do not use mode 1 and auto.
•
CSCsk43922
Symptom: A data path processor (DPP) might fail on an MDS switch running SSI Release 3.2(1) on the SSM. The failure occurs after several days of running traffic when a misbehaving target sends unexpected frames well after the response has already been received from the same target.
Workaround: None.
•
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: Because the the programming request was lost, the only way to retrigger the programming is to withdraw the domain and refresh IVR. Follow these steps:
1.
Identify domains with problem using the show ivr internal dep command.
switch# show ivr internal dep
Internal information for DEP FSM
--------------------------------
vsan domain nh status sync_status req i/f
101 0x61(97) 1001 ALL_DONE OXID|FCID_RW 0 [ fc3/2 ]
102 0x62(98) 1002 ALL_DONE OXID|FCID_RW 0 [ fc3/5 ]
1001 0x9e(158) 101 NONE OXID|FCID_RW 0 [ fc2/16 ]
1002 0x98(152) 102 ALL_DONE OXID|FCID_RW 0 [ fc9/10]Number of DEP entries : 4
After waiting for a few minutes for IVR to stabilize, if the status column for the {vsan, domain} combination is NONE, then this problem has occurred the switch.
2.
Withdraw the troubled domains using the ivr withdraw domain domain vsan vsan-id command.
3.
Readvertise the withdrawn domains using the ivr refresh command.
•
CSCsk49634
Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently high loss rate (above 100ms RTT and 0.5% loss).
Workaround: None.
•
CSCsk49761
Symptom: When IVR exports a new virtual domain and multiple border switches export that virtual domain, some of the entries in the Fibre Channel name server (FCNS) database that correspond to this virtual domain may have partial entries where the port type contains a dash (-). This can then lead to a lack of IVR communication between these devices and other IVR devices.
Workaround: Use the show ivr internal vdri vsan vsan-id domain domain command to determine which border switch is exporting the virtual domain. Then on any of the border switches that is exporting the virtual domain, enter the following command for each device that has a partial FCNS entry:
switch(config)# ivr device pwwn pwwn fcns register vsan vsan-id
In this example, pWWN is the port pWWN of the device and vsan-id is the VSAN that contains the incomplete FCNS entries.
•
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: Set the port mode to F.
•
CSCsk54591
Symptom: In rare cases, if two or more catastrophic exceptions affecting the MDS arbiter occur in quick succession, it is possible that an MDS 9500 Series switch will completely reset.
Workaround: None.
•
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.
•
CSCsl73987
Symptom: In rare instances, when a SCSI I/O is in progress in Cisco SME and it is aborted by the host, the Cisco SME interface may fail and a reset may occur.
Workaround: This issue is resolved.
•
CSCin95789
Symptom: When you configure Cisco Traffic Analyzer to capture traffic on one or more interfaces on a Windows platform, the configuration web page might not show that the interface has been selected for traffic capture even though traffic capture on that interface is enabled.
Workaround: Check the logs to clarify that the correct interface has been selected.
•
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: Before downgrading, remove the IPFC interface on the module and then recreate the IPFC interface after the downgrade is complete.
•
CSCse47687
Symptom: If IP ACLs are applied to any IP Storage Gigabit Ethernet port, implicit deny does not take effect.
Workaround: Configure explicit deny on the port.
•
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: None.
•
CSCsg19303
Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.
Workaround: Increase the FSPF cost on the link before it is shut down, so that traffic will flow through an alternate path.
•
CSCsi66310
Symptom: The management port on MDS switches supports one user-configured IPv6 address, but does not support autoconfiguration of an IPv6 address in Cisco SAN-OS Release 3.2(1).
Workaround: None.
•
CSCsj24904
Symptom: On a Gigabit Ethernet interface on an MDS MSM-18/4 module, shut the interface before removing its IP address so that configuration changes on the interface can take effect. This applies only to the Gigabit Ethernet ports in slot 1 of the MDS 9222i switch and the MDS 9216i switch.
Workaround: Always shut the interface using the shutdown command before removing the IP address and making configuration changes.
•
CSCsj72666
Symptom: In certain conditions, an MDS switch may not be able to determine the FC4-type of certain targets. This causes the targets to be listed in the hosts section during a Cisco SME tape group or tape device configuration.
Workaround: Issue the discover scsi-target vsan vsan-id fcid fcid command to re-discover the FC4-type of the targets. A Cisco SME tape group or tape device configuration will now list the targets correctly.
•
CSCsk00953
Symptom: HP Blade Servers that are connected through an HP Virtual Connect (VC) FC module to a Cisco Fabric Switch for HP c-Class BladeSystem using NPIV lose access to LUNs when load balancing on the VC module is switched from 16:1 to 8:1. When the load balancing ratio is 16:1, all servers connect through interface ext1. When the ratio is 8:1, servers 1 and 3 connect through ext1, servers 2 and 4 connect through ext2, and so on. Servers on ext2 are not affected by the switchover. In addition, packets might get dropped when the switchover occurs.
Workaround: None.
•
CSCsk06186
Symptom: In rare situations, on an MDS 9513 director switch, an upgrade fails when a standby supervisor does not come up to a state that the installer recognizes. As a result, the standby supervisor is reloaded to recover and the system runs the older configuration version.
Workaround: Perform the upgrade again.
•
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.
•
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: Enable IVR NAT on both ends of the PortChannel or disable it on both ends.
•
CSCsk49309
Symptom: IPv6 duplicate address detection (DAD) may not always works for the management port.
Workaround: None.
•
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: Manually remove the DMM configuration from the switch before downgrading to a Cisco MDS SAN-OS release that does not support DMM, such as downgrading from SAN-OS Release 3.2(1) to SAN-OS Release 3.1(3). If you forget to remove the configuration before the downgrade, power off the module and purge the configuration on the SSM module by entering the following commands:
switch(config)# poweroff module slot
switch# purge module slot running-config•
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: Reload the SSM.
•
CSCsk87614
Symptom: When NASB is enabled in a VSAN, all targets that are visible in that VSAN are discovered by NASB. If a new target is added to the VSAN, NASB does not automatically discover the new target.
Workaround: To discover the new target, reload the SSM or disable and re-enable NASB in the VSAN.
•
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: Reload the SSM.
•
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: 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.
•
CSCsl12130
Symptom: After a disruptive downgrade or upgrade between SAN-OS Release 3.2(2c) and Release 3.2(1a), issuing a no shutdown command on a Cisco SME interface fails. When issuing the install all command to perform the downgrade process, a warning is issued that indicates that the downgrade will be disruptive if Cisco SME is enabled.
Workaround: Disable Cisco SME before proceeding with the downgrade process. If you perform a disruptive downgrade, then issue the purge module slot running-config command for the MSM-18/4 modules where Cisco SME is configured after the downgrade is complete.
•
CSCsl12611
Symptom: Devices attached on a remote McData switch do not show a correct physical connection on the correct port in Fabric Manager. This occurs because the registered devices in the McData nameserver are shifted by 4 from its actual physical port and Fabric Manager looks at this port address from the nameserver to locate the physical port.
Workaround: None.
•
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: Shut the F port, enable and disable fcdomain persistency for that VSAN, and then bring up the F port.
•
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: If the switch is in the Cisco Ethernet switch family, configure port-fast to resolve the issue. On Ethernet switches from other vendors, apply a similar configuration mode.
•
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: Schedule the data migration job to start more than 5 minutes from the time of scheduling.
•
CSCsl33763
Symptom: In Cisco SME, tape device names can not include special characters (such as hyphens or underscores). This will cause future tape device creations for a tape group to fail.
Workaround: Use only alpha-numeric values for tape device names.
•
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: Run both fabrics with the same software image.
•
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: 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.
•
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) thru Generation 2 modules. LUN 0x45F0 corresponds to HPUX's Volume Set Address <VBUS ID: 0xB, Target ID: 0xE, LUN: 0x0>.
Workaround: Do not use LUN 0x45F0 and LUN 0x50F0 when Generation 2 modules are present in the fabric.
•
CSCsi56167
Symptom: The response time shown in the output of a ping ip-address command may not be accurate if there is an MDS MSM-8/4 in the path.
Workaround: Use the ips measure-rtt command to measure the round trip time.
•
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: None.
•
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: Perform a rescan at the host level or a flap of the target port to allow Cisco SME to rediscover these newly added tape drives.
•
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.
•
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: Unmount and remount the tape from the backup application to resolve this issue.
•
CSCsm15874
Symptom: In rare cases, when Cisco SME attempts to perform a tape device discovery of the backend tapes, a SCSI command can stall. This may cause Cisco SME to remain in the device discovery phase.
Workaround: Reload the module.
•
CSCsm17768
Symptom: There is a observable performance drop for backup and restore when Cisco SME is introduced between a host and tape due to the increased latency.
Workaround: None.
•
CSCsm18303
Symptom: In certain cases with the Tape Recycle policy enabled in Cisco SME, a new key is generated when a tape is recycled and the old key is not purged.
Workaround: Manually purge the older version of the key.
