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.
Downloading Software
To download the latest Cisco software, access the Software Center at this URL:

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 3.0(2j) add-on image is compatible with the Cisco MDS SAN-OS Release 3.0(2a) image and the Cisco MDS SAN-OS Release 3.0(2b) image.
Limitations
This sections lists limitations or restrictions associated with this release.
Configuration Limits
Table 2 describes SANTap configuration limits associated with SSI 3.0(2j).
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(2) to avoid any traffic disruption.
For information on how to reconfigure the SSM ports, refer to the "Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.0(2)" section of the Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.0(2).

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.

Severity 3R
O
Resolved Caveats
•CSCse58756
Symptom: While testing a configuration with 512 sessions, SANTap crashed.
Workaround: None. This issue is resolved.
•CSCsf98427
Symptom: The QLogic 2460 HBA fails to remote boot when it connects to a VT instantiated by SANTap on the SSM because the QLogic 2460 BIOS sends a test ready unit with an invalid command reference number (CRN) and task attribute field. This same HBA can boot when SANTap and the SSM are not part of the configuration.
Workaround: None. This issue is resolved.
•CSCsg04686
Symptom: An internal call (ScsiSend) was failing because the SCSI DL exceeded 59.9K of read/write requests. This resulted in a memory error.
Workaround: None. This issue is resolved.
Open Caveats
•CSCsg24501
Symptom: If you use the no ssm enable feature santap force command to unprovision SANTap on the SSM, the SANTap configuration is not properly removed.
Workaround: Do not use the force option.

Obtaining Technical Assistance
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:
http://tools.cisco.com/RPF/register/register.do
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.
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:
http://www.cisco.com/techsupport/contacts
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.
