Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the I/O board. These programs are the primary method of testing the major
components of the server.
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.
The following sections contain the error codes that might appear in the detailed test
log and summary log when running the diagnostic programs.
Note: When running F2 diagnostics on xSeries 440 memory, a failure or error
message will be recorded in both the diagnostics log and the service
processor log.
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.
iii is the three-digit device ID.
v When running F2 diagnostics on xSeries 440 memory, this parameter will
identify the failed memory DIMM as well as identifying the SMP
Expansion Module in which the failed memory DIMM is located.
A parameter of
″
0xx
″
indicates the lower SMP Expansion Module, and
″
1xx
″
indicates the upper SMP Expansion Module.
A typical memory error in the xSeries 440 will be similar to the following:
201-200-006-20030506-04-System Memory: Failed
In the above example, “006” indicates DIMM slot 6 on the lower SMP
Expansion Module. A memory error in DIMM slot 6 on the upper SMP
Expansion Module would be recorded as “106”. See diagnostic error
codes 201-xxx-Ynn and 201-xxx-Y99 at “Diagnostic error codes” on page
162.
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.
