A drive is Defunct on controller
[number], channel [number], SCSI ID [number].
Explanation: SCSI channel is
not operational.
Action:
- Check in the following order:
- Power to external enclosures,
connections
- Cables for proper seating
- Damage or bent or pushed pins,
termination (for non-back plane systems), back planes, adapter and drives.
If no connection problems can be identified,
then the replacement order for parts is termination (for non-back plane systems),
cables, back planes, adapter and drives. Before replacing a drive or adapter
ensure that they are updated with the latest firmware and still fail.
