Slow Backup Operations 7
Many factors can make backups appear to be slow. To achieve the highest
possible transfer rate, the LTO-3 Half-Height Tape Drive:
• MUST be attached to a Low Voltage Differential (LVD) SCSI
controller capable of a minimum of 80 Mbytes per sec., and
• MUST NOT share the same SCSI bus as another active SCSI device
such as hard drives.
1 Verify that the tape drive is attached to an LVD SCSI controller. You
can do this by:
• Watching the system the startup process
• Examining the system startup log files
IF the tape drive is . . .
to an LVD SCSI controller, THEN . . .
attached proceed to step 2 of this
procedure to determine
whether the tape drive shares
the SCSI bus with another
active SCSI device.
not attached attach the tape drive to an LVD
SCSI controller to achieve the
best possible hardware
performance for the best
possible transfer rate.
