Error code format

This section provides an explanation of the encoded
non-SCSI and SCSI POST error codes.
Error messages are displayed on the screen as three, four,
five, eight, twelve, or thirteen digits. An "X" in an error
message can be any number or letter. The shorter POST
errors are highlighted in the Symptom-to-FRU Index.
Some digits will represent different information for SCSI
errors versus non-SCSI errors.
The following figure shows which digits display the shorter
POST errors. The figure also defines additional SCSI
information.
Notes

supersede this list.
Duplicate SCSI ID settings will cause misleading
error symptoms or messages.
