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 powered-on before you power-on
the server.
2.
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.
The last device in each SCSI chain is terminated correctly.
5.
The SCSI devices are configured correctly.
