Error Message
Explanation and Error Recovery Procedure
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Read command failed
SCSI sense key = 0x3 (Medium Error)
Tar: tape read error"
This may occur when the NAC is attempting to verify a backup tape or during a restore from tape.
This can be seen in the following maintenance routines:
"Backup Customer Database" routine (online or offline) verifying a damaged
tape
Midnight backup routine verifying a damaged tape
"Restore Customer Database" routine (offline only) reading from a damaged
tape
"Tape ID Display" routine reading from a damaged tape
Retry the routines with the same tape. If the error persists, try the routine again with a different
tape.
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Read command failed
SCSI sense key = 0x5 (Illegal Request)"
The tape operation could not find the files for which it was asked to look. For most NAC routines,
the tape that is needed is the "Customer Application Software" tape. This could mean that the
application tape was not created properly or the wrong tape was inserted into the tape drive.
This can be seen in the following maintenance routines:
"Tape ID Display" reading from an incorrect or blank tape
"Restore Customer Database" reading from an incorrect or blank tape
"Load New Software Release" reading from an incorrect or blank tape
Check you have inserted the proper application software tape into the tape drive. If the proper
tape is in the tape drive and the error persists, a replacement tape should be made for your sys-
tem.
