Check components

Use this procedure to check system components. For
more information on the commands used in this
procedure, refer to CLI provides an ASCII-based
interface on page iii in the Appendix.

Check SCSI devices

1 Check SCSI devices to make sure they are all
set to different SCSI IDs.
By default, the iPBridge SCSI ports use SCSI
ID 7 so drives should use IDs 0 through 6 and 8
through 15.
2 Check the SCSI device power. Make sure the
devices are powering up.
3 Watch the drive lights before, during, and after
startup. Many drives have term power lights
that should be on before startup and turn off
when system boots.
4 Verify the external terminator is the correct type
and does not have damaged pins.

5 Check cable integrity. Check the cables for
solid connections. Make sure they are screwed
down. Inspect cable ends for bent pins.
6 If termination is correct, and the problem
persists, try drives one at a time with different
cables, adding drives and cables until the
problem occurs. This helps pinpoint the drive or
cable causing the problem.
7 Check with the manufacturer of SCSI device(s)
for further troubleshooting methods.
If SCSI devices appear to be working, move on to
the iPBridge SCSI port section.

Check the iPBridge SCSI port

1 Verify the iPBridge has its termination set
properly. By default, termination is
2 Either through the ATTO ExpressNAV or CLI,
perform a SCSI bus scan on each SCSI port.
If no devices appear, re-check SCSI cables and
termination. If garbage information appears,
the problem is most likely a bad SCSI cable or
enabled
