Export the cartridge with the "!" and inspect it for
damage. If it is damaged or if it has exceeded
its usage life, then discard it. Otherwise, clean
the drive and try to use the cartridge again. See
” on page 42. If the same
cartridge generates the "!" again then discard that
cartridge.

SCSI ID
Changed drive SCSI ID, but the host server does not
recognize the new ID.
•
Make sure that all SCSI devices on the same bus
have unique ID numbers.
•
Reboot the host server.
•
If the SCSI bus is narrow (50-pin) only SCSI IDs 0
through 7 are available.
•
Cycle power on the autoloader.
Autoloader Performance
The autoloader is not efficiently backing up data.
•
Make sure the autoloader and tape drive are
on their own SCSI bus and not daisy-chained
to another tape drive or to the hard drive being
backed up.
•
Make sure the autoloader is connected to a LVDS
SCSI bus and there are no SE devices on the
same bus, because this will cause the entire bus
to negotiate down to SE speed.
•
Use an Ultra160 or Ultra320 SCSI bus and
high-quality LVDS cabling with the DAT 72X10
1U autoloader.
•
Do not connect the autoloader to a narrow SCSI
bus.
•
Try a new cartridge. A marginal cartridge can
cause performance problems due to bad spots on
the tape requiring retries.
•
Backing up data that compresses poorly or is
already compressed will lower performance.
•
Check the size of the files. Small file size can
impact performance.
•
Confirm that the backup application is utilizing
block sizes of 32 KB. Refer to the backup
application documentation for details.
•
Make sure the backup server has enough memory
and processing power to handle the bandwidth of
the backup or restore.
•
Clean the tape drive. See
for instructions.
