v
If the error does not occur, connect one tape drive at a time back to the bus
and repeat step 3 for each tape drive until you can identify which drive is
defective.
Note: Ensure that the SCSI terminator is always on the last tape drive on the
SCSI bus.
4. Determine if the problem is with only one tape drive or with two or more tape
drives.
v
If the problem is with only one tape drive, run the SCSI wrap test on that tape
drive (see Function Code 6 in Table 7 on page 29).
– If the test runs successfully, replace the SCSI terminator first, then the
SCSI cable to that tape drive and interposer (if installed).
– If the test fails, replace the tape drive (see “Removing the SCSI Tape
Drive” on page 71).
v
If the problem is with two or more tape drives, locate the first tape drive that
has the error and replace the SCSI cable that connects the tape drive and
the interposer (if installed).
Fixing an Intermittent Error with a Single Drive on a SCSI Bus
1. Replace the SCSI terminator on the tape drive.
2. Run the operation that caused the error. If the problem persists, the problem
may be with the cable.
3. Isolate which cable is causing the problem by replacing one cable at a time and
running the operation that caused the error after each replacement. If the
problem persists after all cables have been replaced, the problem may be with
the Ultrium Tape Drive.
4. Replace the tape drive (see “Removing the SCSI Tape Drive” on page 71). If the
problem persists, the problem is with your server. Consult your server’s
documentation.
Fixing an Intermittent Error with Multiples Drives on a SCSI Bus
Refer to the server’s error logs to determine which tape drive is the source of the
problem:
v
If only one tape drive is reporting a SCSI failure, replace that tape drive (see
“Removing the SCSI Tape Drive” on page 71).
v
If multiple tape drives are reporting SCSI failures, the problem may be with the
terminator or the SCSI cables:
– Replace the terminator and run the operation that caused the error. If the
problem persists, the problem may be with the cables.
– Isolate which cable is causing the problem by replacing one cable at a time
and run the operation that caused the error after each replacement.
