Explanation and Error Recovery Procedure
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Read command failed
SCSI sense key = 0x8 (Blank Check)"
This error may occur during tape operations where data is read from the tape. The tape opera-
tion tried to read past the end of the last file on the tape. This may signal to the user that the tape
is damaged or blank or that the tape drive itself is not functioning properly.
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
"Tape ID Display"
"Restore Customer Database"
"Load New Software Release"
Perform the routine again to check that the tape is not damaged. Also check that the tape is not
a blank tape. If the error persists, a new "Customer Application Software" tape may have to be
re-ordered. If this does not solve the problem, it is possible that the tape drive is not functioning
properly. Contact your Northern Telecom service representative for further assistance.
"WARNING: MVME167 SCSI error on Tape at SCSI address 4
SDL Write command failed
SCSI sense key = 0x0D (Volume Overflow)"
This error may occur during tape operations where data is written to the tape. The operation tried
to write data past the end of the tape which means that the last file written was probably incom-
plete. This may signal to the user that the amount of data being saved has outgrown the capacity
of the tape. The chances of this happening are very remote.
This can be seen in the following maintenance routines:
"Backup Customer Database" (online or offline)
Midnight backup
Perform the routine again to ensure that the tape was completely rewound. If the error persists,
try using another tape. If this does not solve the problem, contact your Northern Telecom service
representative.
