Introduction
The CSM provides virtualization services that allow the Cisco MDS 9000 Family switches to reallocate physical resources as virtual resources for increased efficiency. The CSM has two hard drives, two internal batteries for backup in case of power failure, and no external ports. The CSM receives and sends data through the switch backplane. The batteries on the CSM provide adequate power to back up data without external power.
See the documents listed in the "Related Documentation" section.
System Requirements
This section describes the system requirements for Cisco MDS SVC Release 1.3(5o).

Image Upgrade
When CSMs are present in a Cisco MDS 9000 Family switch, several kinds of upgrade may be performed as required—a cluster software upgrade, an automatic upgrade when nodes are added, a service mode upgrade, or a switch software upgrade.
You can upgrade to Cisco MDS SVC Release 1.3(5o) from Cisco MDS SVC Release 1.3(5m).
Refer to the Cisco MDS 9000 Family SAN Volume Controller Configuration Guide for more information.
Compatibility Matrix
The latest Cisco MDS SAN-OS Release Compatibility Matrix for IBM SAN Volume Controller Software for Cisco MDS 9000 is available in the following Cisco Systems website.
http://www.cisco.com/en/US/products/hw/ps4159/ps4358/products_device_support_tables_list.html
CSM Backward Compatibility
The CSM is compatible with SAN-OS Release 1.3(x). If you need to downgrade to Release 1.2(x) or earlier, you must power off the CSMs before performing the downgrade (see CSCee69099).
To revert to a release that is earlier than Release 1.3(x), follow these steps:
Step 1
Step 2
Refer to the Cisco MDS 9000 Family SAN Volume Controller Configuration Guide.
Step 3
Step 4
Refer to the "Software Images" chapter in the Cisco MDS 9000 Family Configuration Guide.
New Features
Cisco MDS SVC Release 1.3(5o) is a maintenance release for switches using CSM modules in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.
Note
Cisco SVC Release 1.3(5o) supports additional hardware for the SAN Volume Controller. Refer to the following URL for a list of supported operating systems, HBAs, and storage controllers:
http://www-1.ibm.com/support/docview.wss?rs=539&uid=ssg1S1002375
Limitations
The limitations and restrictions listed in this section apply to all switches in the Cisco MDS 9000 Family that have CSMs installed.
Quorum Disks
If you issue a quorum command, regardless of the outcome of this new quorum command, you may loose your previously configured quorum disk configuration. If you issue a new quorum command, be sure to verify your previous quorum configuration.
World Wide Names
The SVC functionality is only available when CSMs are present in the switch. If you issue a copy running startup command when all CSMs are removed (or powered-down), then SVC supervisor configurations associated with the CSM, including world wide names (WWNs), may be discarded.
Caveats
This section lists the open, resolved, and closed caveats for this release. Use Table 2 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat and "O" indicates an open caveat.

Resolved Caveats
•
Symptom: If a vdisk is mapped to more than one host and the vdisk is moved between I/O groups, the CSM vdisk-to-host mapping data is left in an inconsistent state. Changing the configuration, map, or deleting the host or vdisk might cause a cluster 900.
Workaround: None.
Open Caveats
•
Symptom: If your current configuration is using CSMs and you need to downgrade from Release 1.3(x) or later to any release that is earlier than Release 1.3(1), do not issue the install all command before powering off the CSM(s).
Workaround: Explicitly power off the CSM before issuing the install all command. The CSM was only introduced in SAN-OS Release 1.3(x). See the "CSM Backward Compatibility" section.
•
Symptom: During a switch upgrade, an SVC node may not save its entire state under rare circumstances. This results in that node not being part of the cluster after the switch upgrade. Verify this symptom by issuing the show nodes local command at the
svc-configprompt—the command output displays the following information:–
cluster stateof the affected SVC node will beunconfigured.–
node stateof the affected SVC node will befree.Workaround: Manually remove the SVC node from the cluster and then add the node back into the cluster. Refer to Cisco MDS 9000 Family SAN Volume Controller Configuration Guide for procedural details.

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:
•
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•
In an emergency, you can also reach PSIRT by telephone:

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:

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:
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.
