Determining the Software Version


Note We strongly recommend that you use the latest available software release supported by your vendor for the Cisco MDS 9020 Fabric Switch.


To determine the version of the Cisco MDS 9000 FabricWare software currently running on a Cisco MDS 9020 Fabric Switch using the CLI, log into the switch and enter the show version EXEC command.

To determine the version of the Cisco MDS 9000 FabricWare software currently running on a Cisco MDS 9020 Fabric Switch using the Fabric Manager, from the Switches tab in the information pane, locate the switch using its IP address, logical name, or WWN, and then check its version in the Release column.

Image Upgrade

The Cisco MDS 9000 FabricWare software is designed for high availability environments. As new software releases become available, you can nondisruptively upgrade the switch.

Limitations and Restrictions

This section lists the limitations and restrictions for this release.

Merging Fabrics

You must only configure pWWN-type zoning on an MDS switch running Cisco SAN-OS if there is a Cisco MDS 9020 switch running FabricWare in the same fabric to avoid Inter-Switch Link (ISL) isolation. It is important to remove all non-pWWN-type zone entries prior to merging fabrics.

For additional information on zoning, refer to the Cisco MDS 9020 Fabric Switch Configuration Guide and Command Reference.

Caveats

This section lists the open and resolved caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat, "O" indicates an open caveat, and "C" indicates a closed caveat.

O


Closed FabricWare Caveats

CSCei30894

Symptom: When Cisco VPN client version 3.6.3 is installed but not used, some of the ISLs might be missing from the Fabric Manager map if an MDS 9020 switch is used as a seed switch for the discovery of the fabric. An SNMP GET-BULK timeout occurs because of an incompatibility between the TCP/IP stack on the MDS 9020 switch and the client stack being configured or tuned during installation of the Cisco VPN client on the client itself.

Workaround: If you connect through Cisco VPN client 3.6.3 and then open Fabric Manager, it will discover properly.

Open FabricWare Caveats

CSCei52587

Symptom: If a Cisco MDS 9020 switch is used as the seed switch for Fabric Manager discovery in a mixed fabric of Cisco MDS 9000 Series switches, some ISL links might be missing.

Workaround: Use a Cisco MDS 9100, Cisco MDS 9200, or Cisco MDS 9500 series switch as the seed switch or rediscover the network if it is not possible to have them as seed switches.

CSCsc77866

Symptom: When a fabric including a Cisco MDS 9020 Fabric Switch and third party devices is discovered using Fabric Manager, where the Cisco MDS 9020 Fabric Switch is used as a seed for the discovery, the map might not display some of the end devices (hosts and disks) connected to the third party switches. When the zone with these devices is highlighted on the Fabric Manager map display, the devices on the third party switches are shown as 'not in fabric'. CLI displays for FCNS and zone information are correct.

Workaround: None.

Related Cisco SAN-OS Caveats

Cisco MDS 9000 Family switches must be running Cisco MDS SAN-OS Release 2.1(2) to work properly with a Cisco MDS 9020 switch. This section lists the Cisco SAN-OS caveats related to Cisco FabricWare.

The following caveats are resolved in Cisco SAN-OS Release 2.1(2):

CSCei39900

Symptom: If the Cisco MDS 9020 switch is loaded with more devices than recommended, timeouts may occur on a Cisco MDS 9000 Family switch running Cisco MDS SAN-OS Release 2.1(1a) or earlier, when Name Server queries are issued to the loaded Cisco MDS 9020 switch. The queries are retried to the point where the Cisco MDS 9000 Family switch can crash. In Cisco MDS FabricWare Release 2.1(2), the retries are limited to mitigate this effect.

Workaround: Upgrade the Cisco MDS 9000 Family switches to Cisco MDS SAN-OS Release 2.1(2).

CSCei15625

Symptom: If a device registers symbolic port names on the Cisco MDS 9020 switch, the same symbolic port names cannot be properly propagated across VSANs through an IVR fabric where the Cisco MDS 9020 switch is an edge switch in the IVR topology.

Workaround: None.

CSCei52222

Symptom: When devices with specific FC4-type log-in to a Cisco MDS 9000 Series switch and the Cisco MDS 9020 switch issues a GE_FT query to a Cisco MDS 9000 Series switch running Cisco MDS SAN-OS Release 2.1(1a) or earlier, the query might be rejected. This will result in that name server entry on the Cisco MDS 9020 switch not having FC4 type information of the device logged into the Cisco MDS 9000 Series switch. The affected FC4 type is 255.

Workaround: Upgrade the Cisco MDS 9000 Family switches to Cisco MDS SAN-OS Release 2.1(2).

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.
