SCSI Diagnostic Error Codes
SCSI Error
Codes
The following table lists error codes produced by the SCSI
diagnostic.
All values are in hexadecimal.
If the diagnostic fails, then perform the following steps:
1. Make sure the SCSI device is properly connected to the
system.
2. Reseat the system module and I/O module connection.
3. Run the SCSI diagnostic to verify system operation. If a
failure reoccurs, then replace the FRU listed for that error.
Replace FRUs one at a time, running the SCSI diagnostic
after replacing each one to determine if the failure has been
corrected.
