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.

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 Power down all CSMs using the poweroff module slot command.

Step 2 Remove any CSM-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 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 These Release Notes are specific to Release 1.3(5o). For the entire Release 1.3 documentation set, see the "Related Documentation" section.


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

CSCei89468

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

CSCee69099

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.

CSCed14920

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-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.
