Cisco MDS 9000 Family Release Notes
for Cisco MDS SVC Release 1.3(4m)
CCO Date: May 14, 2007
Text Part Number: OL-6199-01
This document describes the caveats and limitations for the SAN Volume Controller Storage Software (SVC) for the Cisco MDS Caching Services Module (CSM). Use this document in conjunction with documents listed in the "Related Documentation" section.
Note
The previous SVC release was concurrent with SAN OS Release 1.3(1) and the caveats were included in that release note. The SVC caveats are now tracked in this SVC release notes.
For information on IBM TotalStorage SAN Volume Controller Storage Software for the Cisco MDS 9000 Family, refer to the IBM TotalStorage Support website: http://www.ibm.com/storage/support/2062-2300/
Contents
This document includes the following section:
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.
System Requirements
This section describes the system requirements for Cisco MDS SVC Release 1.3(4m).

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
Step 2
Refer to the Cisco MDS 9000 Family SAN Volume Controller Configuration Guide.
Step 3
Step 4
Refer to Chapter 5, "Software Images" in the Cisco MDS 9000 Family Configuration Guide.

Resolved Caveats
•
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 downstatus 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
•
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.
•
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.
•
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-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.

Obtaining Technical Assistance
Note
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.
Cisco Technical Support Website
The Cisco Technical Support 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, 365 days a year at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support 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
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 automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC 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 TAC 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.
