Small computer system interface messages (some models)
If you receive a SCSI error message while using the SCSISelect Utility, use the
following list to determine the possible cause of the error and what action to take.
Note: If your system does not have a hard disk drive, ignore any message that
indicates that the BIOS code is not installed.
One or more of the following might be causing the problem.
• A failing SCSI device (adapter or drive)
• 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
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 the above items are correct, run the diagnostic programs to obtain additional
information about the failing device. If the error remains or recurs, call for service.
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:
