IBM 8649 - Eserver xSeries 225 Maintenance And Troubleshooting Manual page 33

Diagnostic error messages indicate that a problem exists. They are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
Chapter 6, "Symptom-to-FRU index," on page 101 contains the error codes that
might appear in the detailed test log and summary log when the diagnostic
programs are run.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fff is the three-digit function code that indicates the function being
tested when the error occurred. For example, function code 089 is
for the microprocessor.
ttt is the three-digit failure code that indicates the exact test failure that
was encountered. (These codes are for trained service personnel;
see "Diagnostic error codes" on page 103).
iii is the three-digit device ID. (These codes are for trained service
personnel; see "Diagnostic error codes" on page 103).
date is the date that the diagnostic test was run and the error recorded.
cc is the check value that is used to verify the validity of the
information.
text message is the diagnostic message that indicates the reason for the problem.
