Caveats Send documentation comments to [email protected] • CSCsk43927 Symptom: The following Fabric Manager client components that use SSH and Telnet do not work well with NAT: • DMM storage job creation • Cisco SAN-OS software upgrade • Zone activation Workaround: None. • CSCsk90998 Symptom: The signal loss counters in the output of the show interface fcx/y command are not incremented. Workaround: None. • CSCsm13002 Symptom: In rare cases, if a READ command issued by Cisco SME for media identification is dropped or lost, the tape is marked as a clear-text tape. Subsequently, a CHECK_CONDITION with ILI is returned when a READ is issued by the host. This can cause a backup application to mark the tape as read-only. Workaround: Unmount and remount the tape from the backup application to resolve this issue. • CSCsm15874 Symptom: In rare cases, when Cisco SME attempts to perform a tape device discovery of the backend tapes, a SCSI command can stall. This may cause Cisco SME to remain in the device discovery phase. Workaround: Reload the module. • CSCsm17768 Symptom: There is a observable performance drop for backup and restore when Cisco SME is introduced between a host and tape due to the increased latency. Workaround: None. • CSCsm18303 Symptom: In certain cases with the Tape Recycle policy enabled in Cisco SME, a new key is generated when a tape is recycled and the old key is not purged. Workaround: Manually purge the older version of the key. OL-14116-08 Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.3(1c) 45
