Recoverable SCSI I/O error messages
The error messages, documented in Table 6-1, may appear on their own or
in groups depending on what tape operation is being performed. The order
in which the messages appear can also be different for repeated failed tape
operations. This is because the software tape driver may not receive the
error messages from the tape drive firmware in the same order.
Table 6-1
Recoverable SCSI I/O error messages
Error Message
Explanation and Error Recovery Procedure
"FATAL ERROR on MVME167 SCSI ctl x, Tape Drive y
MVME167 SCSI error on Tape at SCSI address y
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.
"NOTICE: Write protected on SCSI tape drive 4"
The cassette tape write protect tab has been moved to the position which disallows any tape
operation to overwrite data onto the tape.
This can be seen in the following maintenance routines:
"Backup Customer Database" (online or offline)
Midnight backup
For instructions on how to write enable the cassette tape, refer to the NAC 2 Installation Guide
(NTP 553-4001-110).
