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.

Refer to the documents listed in the "Related Documentation" section.

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.

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 1.3.1 and above. If you need to downgrade to a release earlier than 1.3(1), you must power off the CSMs before performing the downgrade (see CSCee69099).

To revert to a release that is earlier than Release 1.3(1), follow these steps:


Step 1 Power down all CSMs using the poweroff module slot command.

Step 2 Remove any CSMs related configuration (for example, clusters, back-end storage, virtual disks, and so forth).

Refer to the Cisco MDS 9000 Family SAN Volume Controller Configuration Guide.

Step 3 Save the configuration using the copy running-config startup-config command to save the new configuration into nonvolatile storage.

Step 4 Continue with the manual downgrade procedure.

Refer to Chapter 5, "Software Images" in the Cisco MDS 9000 Family Configuration Guide.


Caveats

This section lists the caveats and corrected caveats for this release.

The following issues are resolved in Release 1.3(4m):

Potential issues with loss of quorum disk in MDS 9216 configurations are resolved. Refer to the following website for details on recommended configurations: http://www-1.ibm.com/support/docview.wss?rs=539&context=STY2LR&q1=ssg1*&uid=ssg1S1001973&loc=en_US&cs=utf-8&lang=en

Under certain circumstances, an SVC node can enter an unconfigured or free state during a switch upgrade. This issue is now resolved.

A memory leak when executing certain CLI commands is resolved.

Sequential read performance is improved.

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

CSCed14360

Symptom: If a switch does not have sufficient PortChannels available for an SVC Interface, it remains in a failure state. This situation occurs if you allocate all 128 PortChannels available in the system. You can verify this failure if you see the node down status in the output of the show interface svc slot/node command. To confirm that this failure is a result of insufficient PortChannels, issue the show port-channel usage command.

Workaround: Identify at least three PortChannels that can be released so they appear in the unused section of the show port-channel usage command output. Use the no interface port-channel number command to delete unneeded PortChannels. Finally, reset the SVC Interface.

Open Caveats

CSCee69099

Symptom: If your current configuration is using CSMs and you need to downgrade from Release 1.3(1) 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(1). See the "CSM Backward Compatibility" section.

CSCef04575

Symptom: SAN-OS Release 1.3(4b) for the Cisco MDS 9000 Family is incompatible with Cisco MDS SVC Release 1.3(4m).

Workaround: None.

CSCed14920

Symptom: During a switch upgrade, a 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-config prompt—the command output displays the following information:

The cluster state of the affected SVC node will be unconfigured.

The node state of the affected SVC node will be free.

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.

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.
