Error Code Format
This section provides an explanation of the encoded non-SCSI and SCSI POST
error codes.
Error messages are displayed on the panel 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:
1. Non-IBM device error codes and documentation supersede this list.
2. Duplicate SCSI ID settings will cause misleading error symptoms or messages.
