SCSI Troubleshooting
If the tape drive passes POST with no power or data
cartridge problems, but is still performing poorly, check for
the following SCSI issues.
For information about possible Fibre Channel problems,
refer to the next section.

SCSI Troubleshooting
Possible Problem
Solution
Your system is not configured to “see”
the tape drive.
Check your system and SCSI bus settings.
Configure your system to recognize the tape
drive.
The SCSI ID is not unique.
Change the SCSI ID. The new ID takes effect the
next time you power on the tape drive.
C3
The parameters for your SCSI adapter
are incorrect.
Check your SCSI controller card. Ensure that it is
LVD for the optimal tape drive performance, or
SE for slower performance.
C1
The SCSI bus is not terminated correctly. Confirm that a terminator is installed on the last
device in the SCSI chain and that it is fully
seated.
C4, C5
The SCSI bus is too long.
For single-ended mode, limit the length of the
SCSI bus to 3 meters. For LVD mode, limit the
length to 25 meters.
Too many devices are connected to the
SCSI bus.
Limit the number of external devices. Try using
the tape drive as a stand-alone device.
The tape drive is operating more slowly
than indicated in its performance
specifications.
For the best performance, make sure your SCSI
controller card can operate at 160 MB/second.
