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, view the Switches tab in the information pane, locate the switch, using the IP Address, Logical Name, or WWN, and check its version in the Release column.

Image Upgrade

When ASMs are present in a Cisco MDS 9000 Family switch, several kinds of upgrade may be performed as required—a previous provider package upgrade, upgrading the SAN-OS Image or reformatting the ASM add-on image.

Refer to the VERITAS Storage Foundation ™ for Networks Installation and Configuration Guide. You can access this document at http://support.veritas.com/.

A printed version of this document is also available through the VERITAS web store:
http://webstore.veritas.com/webstore/en/index.jsp?lang=en&country=US

New Features in VSFN Release 1.3(4b)

VSFN Release 1.3(4b) is a patch release for switches in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.


Note The Release Notes are specific to this patch release. For the rest of the SAN-OS and VSFN Release 1.3 documentation, see the "Related Documentation" section.


This section includes the following topics:

VSFN Add-On Image

High Availability

VSFN Add-On Image

The VSFN Release 1.3(4b) add-on image is compatible with the SAN-OS Release 1.3(4a) image and the SAN-OS Release 1.3(4b) image.

High Availability

VSFN Release 1.3(4b) introduces the VERITAS Storage Foundation for Networks support for high availability (HA). The HA feature in Storage Foundation for Networks is enabled through several concepts, one of which is a Service Group, a collection of entities that failover as a unit in a highly available cluster of ASMs. Service Groups are used to manage a cluster of volume servers for the purpose of providing data redundancy, or allowing objects such as virtual LUNs (VLUNs) to be highly available.

Refer to the VERITAS Storage Foundation ™ for Networks Installation and Configuration Guide. You can access this document at http://support.veritas.com/.

A printed version of this document is also available through the VERITAS web store:
http://webstore.veritas.com/webstore/en/index.jsp?lang=en&country=US

Limitations

This section includes the following topics:

LUN Zoning Support

Read-Only Zoning Support

LUN Zoning Support

Prior to Release 1.3(4b) the LUN zoning feature was not supported for a host that was directly connected to a front-panel port of an ASM accessing a VSFN VLUN.

In Release 1.3(4b) LUN zoning is supported for this configuration.

Read-Only Zoning Support

In Release 1.3(4b) and earlier, the read-only zoning feature is not supported for a host that is directly connected to a front-panel port of an ASM accessing a VSFN VLUN.

Compatibility Matrix

The latest Cisco MDS SAN-OS Release Compatibility Matrix for VERITAS Storage Foundation for Networks Software is available in the following Cisco Systems website.

http://www.cisco.com/en/US/products/hw/ps4159/ps4358/products_device_support_tables_list.html


Note We reccommend that you upgrade to VSFN Release 1.3(4b).

Technical Assistance Center

Cisco Technical Support is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco Technical Support website and the Cisco Technical Support Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco Technical Support inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing 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.

Cisco Technical Support Website

The Cisco Technical Support website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco Technical Support website, go to this URL:

http://www.cisco.com/techsupport

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco Technical Support website.

http://www.cisco.com/techsupport/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.

Cisco Technical Support Escalation Center

The Cisco Technical Support Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the Technical Support Escalation Center with a P1 or P2 problem, a Cisco Technical Support engineer automatically opens a case.
