Problem Solution
DRIVE DOES NOT RESPOND TO
SOFTWARE COMMANDS (The
drive powers up, loads and
unloads cartridges, but will not
respond to any software
commands.)
1. Make sure the tape drive is installed properly on
the SCSI bus.
Make sure you followed the correct procedures,
described in Chapter 2, “Installation”, on page 2-1,
to install the drive on the SCSI bus. The SCSI cable
should be firmly connected. Also make sure the
connector pins are not bent or broken.
2. Perform a SCSI bus reset.
If a SCSI bus reset does not cause the drive to
reset, check the following:
v
Is there a broken SCSI cable or defective
connector?
v Is SCSI cable pin 1 aligned with SCSI connector
pin 1?
v
Is the drive set to a unique SCSI ID?
If a SCSI bus reset does cause the drive to reset,
the problem may be with the SCSI bus addressing
or termination. Do the following:
v
Check the SCSI bus addressing and termination.
v
Try another known good SCSI device in the
same location.

1. Clean the drive.
See “Using cleaning cartridges” on page 3-4 for
cleaning instructions; LED 2 flashes yellow when
the drive needs to be cleaned. Use only an
IBM-approved VXA tape cleaning cartridge.
2.
Retry the read or write operation.
If the drive was attempting to perform a read or
write operation when the error occurred, eject the
cartridge, insert it again, and retry the operation. If
this does not solve the problem, load a new
cartridge and try again.
3. Power cycle the drive.
If the problem persists, turn the drive off, then
back on again.
