2. A single problem might cause several error messages. When this occurs, work to
correct the cause of the first error message. After you correct the cause of the first
error message, the other error messages usually will not occur the next time you
run the test.
POST error messages
The table,“POST error codes” on page 122, provides information about the POST error
messages that can appear during startup.
Event/error logs
The POST error log contains the three most recent error codes and messages that the
system generated during POST. The System Event/Error Log contains all error
messages issued during POST and all system status messages from the Netfinity
Advanced System Management Processor.
To view the contents of the error logs, start the Configuration/Setup Utility program;
then, select
Event/Error Logs from the main menu.
Small computer system interface messages
The following table lists actions to take if you receive a SCSI error message.
Note:
If your server does not have a hard disk drive, ignore any message that
indicates that the drive is not installed.
You will get these messages only when running the SCSISelect Utility. See “SCSI error
codes” on page 128.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of your 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.
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 and are described
in the
Hardware Maintenance Manual .)
