Caveats
Resolved Caveats
• CSCsy74340
Symptom: The SCSI Flow Manager (SFM) failed as a result of a link flap of a SCSI-FLOW target
configured for IVR.
Workaround: This issue is resolved.
• CSCsz21804
Symptom: After you perform an in-service software upgrade (ISSU) from SAN-OS Release 3.x to
NX-OS Release 4.x, the show fcs database command does not display the attached pWWNs.
Workaround: This issue is resolved.
• CSCsz53741
Symptom: When a crossbar module fails because of sync loss, MDS 9000 switches try to recover
the fabric module by power cycling the crossbar. This may result in lost data path connectivity
because the recovery may not be complete.
Workaround: This issue is resolved.
• CSCta47460
Symptom: The Online Health Management System (OHMS) did not receive a congestion status
when the ports were in a hardware failure state.
Workaround: This issue is resolved.
• CSCta67430
Symptom: If a host issues a tape read command with the suppress incorrect-length indicator (SILI)
bit set, it is possible for the target to return a good status and not send the full read data length
requested in the read command. If this occurs, FCIP tape acceleration can leave the exchange entry
in an error recovery state on the FCIP target side, and remove the exchange entry on the FCIP host
side. As a result, FCIP loss of sync failure can occur.
Workaround: This issue is resolved.
• CSCtb28442
Symptom: End of sequence is not set for STK drives when the host requests more data than what is
written to the tape.
Workaround: This issue is resolved.
