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

•Determining Software Version Compatibility

•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.

Determining Software Version Compatibility

Table 3 lists the software versions that are compatible in a mixed SAN environment, and the minimum software versions that are supported. We recommend that you use the latest software release supported by your vendor for all Cisco MDS 9000 Family products.

Table 3 Software Version Compatibility

NX-OS Release 5.0(x)

Minimum NX-OS or SAN-OS Release

Tested NX-OS and SAN-OS Releases

NX-OS Release 5.0(1a)

SAN-OS Release 3.3(1c) or later

SAN-OS Release 3.3(1c), 3.3(5)

NX-OS Release 4.1(1b) or later

NX-OS Releases 4.1(1b), 4.2(5)

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.

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 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.

For information on Cisco MDS 9000 hardware and software compatibility, refer to the Cisco MDS 9000 SAN-OS Hardware and Software Compatibility Information.

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:

•General Upgrading Guidelines

•FICON Supported Releases and Upgrade Paths

•Upgrading with IVR Enabled

•Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.3(5b)

•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

•Upgrading an MDS 9222i Switch

General Upgrading Guidelines

Use the following guidelines when upgrading to Cisco MDS SAN-OS Release 3.3(5b):

•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(5b). 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(5b) 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.

Use Table 7 to determine your nondisruptive upgrade path to Cisco MDS SAN-OS Release 3.3(5b).

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(4). 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 "General Upgrading Guidelines" 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(5a).

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(5b)

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(5b).

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(5b)" 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(5b) 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(5b), 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(5b) 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(5b) 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(5b):

•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 the "FICON Downgrade Paths" section.

Use Table 8 to determine the nondisruptive downgrade path from Cisco SAN-OS Release 3.3(5b). 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 3.3(5b) 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(5b) 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(5b). A nondisruptive downgrade from NX-OS 4.1(1x) to SAN-OS 3.3(5b) 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(5b)

Cisco MDS SAN-OS Release 3.3(5b) is a maintenance release that includes bug fixes. There are no new features in this release.

Note These release notes are specific to this release. For the complete Release 3.x documentation set, see the "Related Documentation" section.

•HTTP Transport Method Not Supported in Call Home

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(5b) 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.

Cisco Storage Media Encryption

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(5b) 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(5b), 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 Cisco MDS Release NX-OS 4.1(x) does not support Data Mobility Manager (DMM) in any SAN-OS Release 3.3(x) or in any SAN-OS Release 3.2(x). To use the Cisco Fabric Manager GUI for DMM, both Cisco Fabric Manager and DMM must be running Cisco NX-OS or SAN-OS software from the same release series.

A Supervisor-2 Module Might Reset in Switches Running SAN-OS Release 3.2(x)

An MDS 9000 switch with a Supervisor-2 module might switch over to the standby supervisor module with a reset reason of Kernel Panic. Although there is no workaround for this issue, it happens very rarely. Additional instrumentation and checks have been added to SAN-OS Release 3.3(1c) and later and to NX-OS Release 4.2(x) to ensure that kernel panic does not occur. DDTS CSCsx18173 describes this issue.

Limited ISSU Support on the MDS 9222i Switch

An in-service software upgrade (ISSU) from SAN-OS Release 3.3(5b) 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(5b) 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(5) 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

•CSCto68011

Symptom: The fcdomain service on both supervisor modules fails, which results in a reload of the device. An error message similar to the following is displayed:
'' %SYSMGR-2-SERVICE_CRASHED: Service ''fcdomain'' (PID 4688) hasn't caught signal 11 
(core will be saved)'' 
This issue affects the following products when they have SNMP configured:

–Cisco MDS 9000 Series Multilayer switches

–Cisco Nexus 5000 Series switches and Cisco Nexus 2000 Series, running in FC switching mode (NPV mode is not affected).

The following products are confirmed not vulnerable:

–Cisco Nexus 7000 Series switches

–Cisco Nexus 4000 Series switches

Workaround: This issue is resolved. The following workaround is available.

Infrastructure Access Control Lists:

Caution Because the feature in this vulnerability uses UDP as a transport, it is possible to spoof the sender's IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses.

Although it is often difficult to block traffic that transits a network, it is possible to identify traffic that should never be allowed to target infrastructure devices and block that traffic at the border of networks. Infrastructure Access Control Lists (iACLs) are a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The iACL example below should be included as part of the deployed infrastructure access-list which will protect all devices with IP addresses in the infrastructure IP address range:
    !---
    !--- Feature: SNMP
    !---
    !--- 
    !--- Permit SNMP traffic from trusted sources. 
    !--- 
    ip access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD 
        INFRASTRUCTURE_ADDRESSES WILDCARD eq port snmp
    ip access-list 150 permit tcp TRUSTED_SOURCE_ADDRESSES WILDCARD 
        INFRASTRUCTURE_ADDRESSES WILDCARD eq port snmp
    !--- 
    !--- Deny SNMP traffic from all other sources. 
    !--- 
    ip access-list 150 deny udp any any eq port snmp
    ip access-list 150 deny tcp any any eq port snmp
    !---
    !--- Permit/deny all other Layer 3 and Layer 4 traffic in 
    !--- accordance with existing security policies and 
    !--- configurations.  Permit all other traffic to transit the
    !--- device.
    !---
    access-list 150 permit ip any any
    !--- Apply access-list to management interface
    interface serial 2/0
     ip access-group 150 in

•CSCta98668

Symptom: The FCS process received invalid packets from other switches due to heavy FCS traffic from SNMP at the time of topology discovery (possibly from SANScreen). As a result, the FCS process failed.

Workaround: This issue is resolved.

•CSCte46238

Symptom: The SSM module, DS-X9032-SSM, reloaded because of the ACL Manager:

switch# show system reset-reason module x

*************** module reset reason (x) *************

Service name : ACL manager

Workaround: This issue is resolved.

•CSCto05539

Symptom: There needs to be a way to differentiate crc-errors from legitimate serdes-errors or sync-losses so that it is not necessary to take down the supervisor module when there are crc-errors. Whenever there are crc-errors, the crossbar links can be resynced without using the error-recovery policy.

Workaround: This enhancement request is resolved.
