Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.2(3)

OL-14116-04

Caveats

• CSCsg19303

Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.

Workaround: Increase the FSPF cost on the link before it is shut down, so that traffic will flow

through an alternate path.

• CSCsi66310

Symptom: The management port on MDS switches supports one user-configured IPv6 address, but

does not support autoconfiguration of an IPv6 address in Cisco SAN-OS Release 3.2(1).

Workaround: None.

• CSCsj24904

Symptom: On a Gigabit Ethernet interface on an MDS MSM-18/4 module, shut the interface before

removing its IP address so that configuration changes on the interface can take effect. This applies

only to the Gigabit Ethernet ports in slot 1 of the MDS 9222i switch and the MDS 9216i switch.

Workaround: Always shut the interface using the shutdown command before removing the IP

address and making configuration changes.

• CSCsj72666

Symptom: In certain conditions, an MDS switch may not be able to determine the FC4-type of

certain targets. This causes the targets to be listed in the hosts section during a Cisco SME tape group

or tape device configuration.

Workaround: Issue the discover scsi-target vsan vsan-id fcid fcid command to re-discover the

FC4-type of the targets. A Cisco SME tape group or tape device configuration will now list the

targets correctly.

• CSCsk00953

Symptom: HP Blade Servers that are connected through an HP Virtual Connect (VC) FC module to

a Cisco Fabric Switch for HP c-Class BladeSystem using NPIV lose access to LUNs when load

balancing on the VC module is switched from 16:1 to 8:1. When the load balancing ratio is 16:1, all

servers connect through interface ext1. When the ratio is 8:1, servers 1 and 3 connect through ext1,

servers 2 and 4 connect through ext2, and so on. Servers on ext2 are not affected by the switchover.

In addition, packets might get dropped when the switchover occurs.

Workaround: None.

• CSCsk06186

Symptom: In rare situations, on an MDS 9513 director switch, an upgrade fails when a standby

supervisor does not come up to a state that the installer recognizes. As a result, the standby

supervisor is reloaded to recover and the system runs the older configuration version.

Workaround: Perform the upgrade again.

• CSCsk35725

Symptom: Fabric Manager takes 2 to 3 minutes to bring up the DMM job creation wizard in a setup

with 25 switches, 400 enclosures, and 2400 entries in the name server.

Workaround: None.

• CSCsk35951

Symptom: In a configuration with a PortChannel with FCIP members and write acceleration in use,

if IVR NAT is enabled on one end of the PortChannel and not enabled on the other end, then traffic

over the FCIP tunnel might fail.

Workaround: Enable IVR NAT on both ends of the PortChannel or disable it on both ends.
