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

“Cleaning the tape drive”onpage42. If thesame

cartridge generates the "!" again then discard that

cartridge.

“Operator control panel (OCP) overview” on page 29

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.

•

Cyclepower on theautoloader.

Autoloader Performance

The a

utoloader is not efﬁciently backing up data.

• Mak

sure the autoloader and tape drive are

heir own SCSI bus and not daisy-chained

another tape drive or to the hard drive being

cked up .

•

ke sure the autoloader is connected to a LVDS

CSI bus and there are no SE devices on the

amebus,because this will causethe entire bus

negotiate down to SE speed.

• Use

an Ultra160 or Ultra320 SCSI bus and

high-quality LVDS cabling with the DAT 72X10

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 c an

impact performance.

•

Conﬁrm that the backup application is utilizing

block sizes of 32 KB. Refer to the backup

application documentation for detail s.

•

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

“Cleaning the tape drive” on page 42

for instructions.
