Problem
You cannot back
up
or restore.
Possible Cause
The tape drive's SCSI ID may conflict
with another device.
Your backup software may have
encountered a problem.
The operator may not know how to use
your backup application, especially if the
operator is new or has been away from the
job for a while.
The cartridge may be defective.
The cartridge format may have been
destroyed by a bulk eraser. That process
removes the reference points needed by
the tape drive to read and write the tape.
The cartridge may not be the correct
format.
The drive may be used in an unsuitable
location or outside its operating limits. If
it is unusually hot, cold, damp, dry, or
dusty, the tape drive may not perform
well.
A new operating system has been
installed without the correct drivers for
the tape drive.
Potential Solution
Check that the tape drive SCSI ID is not
the same as that of any other device
attached to the same SCSI controller.You
can run TapeAssure to check the SCSI
IDs of attached devices.
NOTE: If you change an external tape
drive's SCSI ID, unplug the power cord to
the tape drive. Then plug it back in again.
This completes the tape drive's resetting
of the SCSI ID.
Refer to the user documentation for your
backup software. This should contain a
list of error conditions and suggested
remedies.
Ask the person to repeat the operation
while you watch, to check that they are
not omitting some vital step.
Try the operation with a different
cartridge. Make sure the cartridge is fully
inserted into the tape drive. If you have
been using the same cartridge for a long
time, copy the data on it to a new cartridge
and discard the old one.
Use a new tape. Any data stored on the
tape will have been erased by the bulk
eraser.
Check that you are using the right type of
cartridge. (See "Choosing Tapes for Your
Tape Drive" on page 4-3.) If you are using
a different brand of cartridge, it may not
be of sufficient quality.
Check the environmental conditions
against the drive's specified limits
(described in Appendix A). If they are
outside the limits, move the drive to a
more suitable site.
Install the correct driver software for the
operating system and tape drive.
