If the diagnostics are successful, it may be necessary to perform an
operating system specific recovery process, or reinstall the operating system.
If unable to load standalone diagnostics:
a. Verify proper SCSI bus termination.
b. Check SCSI cabling.
c. It is possible that another attached SCSI device is causing the problem.
Disconnect the signal and power cables from any other SCSI devices
attached to the SCSI adapter that the CD-ROM drive is attached to.
Try to boot the standalone diagnostics again.
If unable to load standalone diagnostics go to step 4.
If standalone diagnostics load, one of the disconnected devices removed
is causing the problem. Reconnect the devices one at a time and retry
the boot operation until the problem recurs and replace the device that
caused the problem. (If the problem appears to be one of the SCSI
devices, be aware it could be either the SCSI device or the SCSI
adapter). Go to "MAP 0410: Repair Checkout" in the Diagnostics
Information for Multiple Bus Systems.
4. It is possible that another installed adapter is causing the problem.
Remove all installed adapters except the one the CD-ROM drive is attached
to and the one used for the console.
Try to boot the standalone diagnostics again.
If unable to load standalone diagnostics go to step 5.
If standalone diagnostics load, re-install adapters (and attached devices as
applicable) one at a time and retry the boot operation until the problem
recurs. Then replace the adapter or device that caused the problem (system
board can also cause the device or adapter to fail). Go to "MAP 0410: Repair
Checkout" in the Diagnostics Information for Multiple Bus Systems.
5. Either the CD-ROM drive, SCSI adapter, the graphics adapter, or the system
board is most likely defective. A tty terminal attached to the serial port also can
be used to determine if the graphics adapters is causing the problem. This is
done by removing the graphics adapter, attaching a tty to the serial, and retrying
standalone diagnostics. If the standalone diagnostics load, the graphic adapter
should be replaced.
If the CD-ROM drive is attached to a SCSI adapter card rather than the
integrated SCSI adapter on the system board.
– Replace SCSI adapter.
– Replace riser card.
Replace system board.
If you replaced the indicated FRUs and the problem is still not corrected, or
the above descriptions did not address your particular situation, go to“MAP
1540: Minimum Configuration” on page 2-21.
