Determining the Software Version
Note
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.
Compatibility
The SSI image release 3.0(1) add-on image is compatible with the Cisco MDS SAN-OS Release 3.0(1) image.
LUN Resizing
SANTap supports LUN resizing if the lun-size-handling field is enabled in the Data Virtual Target. If you are downgrading to Cisco SAN-OS Release 3.0(1) or earlier, you must recreate a DVT in order to view resized LUNs.
Limitations
This sections lists limitations or restrictions associated with this release.
Configuring SSM Ports in Auto Mode
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode. Because auto mode is the default for releases prior to Release 3.0(1), you should modify the configuration of the ports before upgrading the SAN-OS software image to Release 3.0(1) to avoid any traffic disruption.
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 might cause a disruption if the port is currently operating in E mode.
To make the configuration change without any traffic disruption, follow these steps:
Step 1

Caveats
This section lists the open and resolved caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "O" indicates an open caveat and "R" indicates a resolved caveat.

Resolved Caveats
•
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.
•
Symptom: While downgrading from Cisco SAN-OS Release 3.0(1) to Release 2.x, under some circumstances the downgrade of the SSM or ASM might fail.
Workaround: Power down the SSM or ASM, perform the downgrade and then bring-up the new SSM or ASM with the new bootvar set to the 2.x SSI image.
•
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.
switch#delete modflash://ssm-slot-number-1/isapi_debug.conf2.
switch#reload module ssm-slot-number3.

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.
Cisco Technical Support & Documentation Website
The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
