Diagnostic programs and error messages

If you receive a SCSI error message, one or more of the following might be causing the
problem:
• A failing SCSI device (adapter, drive, controller)
• An improper SCSI configuration
• Duplicate SCSI IDs in the same SCSI chain
• An improperly installed SCSI terminator
• A defective SCSI terminator
• An improperly installed cable
• A defective cable
To solve the problem, verify that:
• The external SCSI devices are turned on. External SCSI devices must be turned on
before the server.
• The cables for all external SCSI devices are connected correctly.
• The last device in each SCSI chain is terminated properly.
• The SCSI devices are configured correctly.
If you have verified these items and the problem persists, run the diagnostic programs
to obtain additional information about the failing device. If the error remains or
recurs, call for service.
Note: If your server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
You will get these messages only when running the SCSISelect Utility.
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.
