All SCSI devices must be powered-on before you power-on the server. 2. The cables for all SCSI devices are connected correctly. 3. The last device in each SCSI chain is terminated correctly. 4. The SCSI devices are configured correctly. Undetermined problems You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative. Notes 1. If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see "Resolving configuration conflicts" on page 39. 2. A corrupt CMOS can cause undetermined problems. Check the LEDs on all the power supplies. If the LEDs indicate the power supplies are working correctly, return here and do the following: 1. Power-off the computer. 2. Be sure the system is cabled correctly. 3. Remove or disconnect the following (one at a time) until you find the failure (power-on the computer and reconfigure each time).

SCSI error codes
Error Code
FRU/Action
All SCSI Errors
One or more of the following
might be causing the
problem:
±
A failing SCSI device
(adapter, drive,
controller)
±
An improper SCSI
configuration or SCSI
termination jumper
setting
±
Duplicate SCSI IDs in
the same SCSI chain
±
A missing or improperly
installed SCSI
terminator
±
A defective SCSI
terminator
±
An improperly installed
cable
±
A defective cable
1.
All SCSI devices
must be powered-on
before you power-on
the server.
2.
The cables for all SCSI
devices are connected
correctly.
3.
The last device in each
SCSI chain is
terminated correctly.
4.
The SCSI devices are
configured correctly.
Undetermined problems
You are here because the diagnostic tests did not identify
the failure, the Devices List is incorrect, or the system is
inoperative.
Notes
1.
If you suspect a software mismatch is causing
failures (solid or intermittent), be sure to see
“Resolving configuration conflicts” on page
39.
2.
A corrupt CMOS can cause undetermined
problems.
Check the LEDs on all the power supplies.
If the LEDs
indicate the power supplies are working correctly, return
here and do the following:
1.
Power-off the computer.
2.
Be sure the system is cabled correctly.
3.
Remove or disconnect the following (one at a time)
until you find the failure (power-on the computer and
reconfigure each time).
