SCSI error codes Error code All SCSI Errors One or more of the following might be causing the problem: v A failing SCSI device (adapter, drive, controller) v An improper SCSI configuration or SCSI termination jumper setting v Duplicate SCSI IDs in the same SCSI chain v A missing or improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable FRU/action 1. External SCSI devices must be turned on before you turn on the server. 2. Make sure that the cables for all external SCSI devices are connected correctly. 3. If you have attached an external SCSI device to the server, make sure the external SCSI termination is set to automatic. 4. Make sure that the last device in each SCSI chain is terminated correctly. 5. Make sure that the SCSI devices are configured correctly.

SCSI error codes
Error code
FRU/action
All SCSI Errors
One or more of the
following might be causing the problem:
v
A failing SCSI device (adapter, drive,
controller)
v
An improper SCSI configuration or SCSI
termination jumper setting
v
Duplicate SCSI IDs in the same SCSI
chain
v
A missing or improperly installed SCSI
terminator
v
A defective SCSI terminator
v
An improperly installed cable
v
A defective cable
1.
External SCSI devices must be turned on before you turn on
the server.
2.
Make sure that the cables for all external SCSI devices are
connected correctly.
3.
If you have attached an external SCSI device to the server, make
sure the external SCSI termination is set to automatic.
4.
Make sure that the last device in each SCSI chain is terminated
correctly.
5.
Make sure that the SCSI devices are configured correctly.
