Error Message
Explanation and Error Recovery Procedure
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Write command failed
SCSI sense key = 0x3 (Medium Error)"
The tape in the drive has a serious problem. It may have been damaged from a previous tape
operation or environmental factors such as dirt, dust, and improper storage could have been
responsible.
This can be seen in any maintenance routine that uses a tape.
Perform the routine several times. If the error persists, replace the tape if possible. Do not at-
tempt to reuse this tape again.
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Write command failed
SCSI sense key = 0x3 (Medium Error)
Tar: tape write error"
The tape operation is attempting to write data to a tape that is potentially damaged. This may
occur when the NAC is attempting to backup the data to a tape during the midnight routines or
other backup operation.
This can be seen in the following maintenance routines:
"Backup Customer Database" routine (online or offline) writing to a damaged
tape
Midnight backup routine writing to 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 Write command failed
SCSI sense key = 0x4 (Hardware Error)"
The tape drive has encountered a hardware problem and is unable to complete the tape opera-
tion.
This can be seen in any maintenance routine that uses a tape.
Perform the routine several times again. Also perform a different tape routine to test if the prob-
lem is isolated to one particular function. If the error persists, the tape drive is probably not func-
tioning properly. Contact your Northern Telecom service representative for further assistance.
