Determining the Software Version


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


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

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

Image Upgrade

If SSMs are present in a Cisco MDS 9000 Family switch, several kinds of upgrade may be performed as required—upgrading a previously provided package, upgrading the SAN-OS image, or reformatting the SSM add-on image.

New Features

This section describes the new features introduced in this release. For more information about the features listed, refer to the documentation set listed in the"Related Documentation" section.

The SSI image release 2.1(2) add-on image is compatible with the Cisco MDS SAN-OS Release 2.1(2) image.

Limitations

The SSI add-on image for release 2.1(2)requires the Cisco MDS SAN-OS Release 2.1(2) image and will not work with earlier releases.

The maximum number of targets supported by SanTap is 16.

Compatibility Matrix

The latest Cisco MDS SAN-OS Release Compatibility Matrix for Storage Service Interface Images is available from the following Cisco Systems website.

Resolved Caveats

There are no resolved caveats for this release.

Open Caveats

CSCeh73149

Symptom: If VSAN suspend/resume is used to facilitate network-level reconfiguration, it might not work.

Workaround: To use VSAN suspend/resume on Cisco MDS SAN-OS with the SSI image release 2.1(2), unprovision SANTap first.

CSCeh93109

Symptom: If a device does not delete objects it has created, unprovisioned SANTap has issues if those objects are present.

Workaround: Unprovision SANTap only after the device has deleted all objects.

CSCsd42944

Symptom: If you make zoning changes while an intelligent application is performing normal storage related operations on the SSM, the console log may fill up with error messages. As a result of the large amount of data to be logged, the console may stop responding and the SSM may fail.

Workaround: Do not make zoning changes in the topology while normal operations are in progress. Make sure any intelligent application running on the SSM has stopped before making any configuration changes.

CSCeh88814

Symptom: The CVT object is not deleted on the Supervisor module when SANTap is unprovisioned.

Workaround: To ensure the deletion on the module, issue the no santap module slot-number appl-vsan vsan-id command to delete the CVT and then unprovision santap.

CSCei48889

Symptom: When multiple initiators (such as backup host and NASB engine) issue SCSI write commands to the IBM-3584, it responds with a SCSI CHECK CONDITION with Sense - 0x03 and ASC/ASCQ = 0x3b/0x00. It does not handle the transition from the host initiator to the NASB engine initiator. In general, this is an issue for all NASB solutions with this tape drive and library combination. This behavior pertains only to the LTO drives on the IBM 3584 library. LTO-2 drives on the same library function correctly.

Workaround: None.

CSCsb98073

Symptom: The data virtual target (DVT) LUNs will not install properly if the control path processor virtual initiator is not in the same zone as the DVT Target.

Workaround: Add a target PWWN to the zone in the control path processor virtual initiator, or issue the shutdown/no shutdown command sequence on the target port after creating the data virtual target.

CSCsd27581

Symptom: The upgrade of an SSM with a configured SSI image may fail under certain conditions. As a result, the install all command fails and all the modules installed in slot numbers greater than the SSM slot number are not upgraded.

This failure happens only if the SSM was initialized with the isapi_debug.conf file installed in the modflash: file system.

In addition, this failure happens if the configured SSI code is version 2.1(2), 2.1(2i), or 2.1(2j) and the user attempts to upgrade to a later version.

This problem does not occur if the SSM is started and is running without the configured SSI boot variable.

Workaround: Perform a disruptive upgrade of the SSM to ensure that the install all command completes successfully. Follow these steps:

1. Use the delete modflash command to remove the isap_debug.conf file from the modflash: file system, as in this example:
switch# delete modflash://ssm-slot-number-1/isapi_debug.conf

2. Use the reload module command to reload the SSM module, as in this example:
switch# reload module://ssm-slot-number

3. Verify that the install all command succeeds once the SSM reaches the OK state.
