Small computer system interface (SCSI) messages
If you receive a SCSI error message while running the SCSISelect Utility program,
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. You must turn on all external SCSI
devices
before turning on 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 remains, 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 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.
Starting the diagnostic programs
To start the diagnostic programs:
1. Turn on the server and watch the screen.
2. When the message F2 for Diagnostics appears, press F2.
If a power-on password is set, the server prompts you for it. Type the power-on
password, and press enter.
3. When the Diagnostic Programs screen appears, select either Extended or Basic
from the top of the screen.
4. Select the test that you want to run from the list that appears; then, follow the
instructions on the screen.
