)Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(1a)
OL-21012-01
Caveats
Workaround: This issue is resolved.
• CSCtb74201
Symptom: When stale, non-advertised IVR virtual domain entries get stuck in persistent storage
service (PSS) after an HA failover, upgrading the switch with these stale entries to SAN-OS Release
3.3(2) or later may fail to clear up these entries because of some corner cases where an unexpected
location of the PSS cursor occurs. This in turn may lead to IVR zone set activation failures.
Workaround: This issue is resolved.
• CSCtd77695
Symptom: When a tape reaches its capacity, IBM TS1120 tape drives send a check condition with
eom = 1 and asc_ascq = 0. Because asc_ascq is not set to End of Medium or Partition, SME
continues to send traffic as if the end of tape is not reached. This situation causes the backup to fail
when it spans across multiple tapes. This problem is specific to IBM TS1120 tape drives.
Workaround: This issue is resolved.
• CSCtd47883
Symptom: In certain rare circumstances, when the IOA cluster membership across the switches
flaps due to a switchover or loss of connectivity to the management interface, certain internal control
messages get dropped, which causes the flows to stay in a stuck state.
Workaround: This issue is resolved.
• CSCtd48744
Symptom: On an MDS 9222i switch, when IVR is enabled in non-NAT mode and the
in-order-guarantee feature is enabled, a route change, such as an ISL going up or down, can cause
an exception similar to the following on Generation 2 or Generation 3 modules:
