b. Confirm that the channels identified from the error in step 2a on page 109
are the cause of the error by verifying that the error presents itself only
when the offending channel is reconnected.
c. Check the termination of the identified channel.
Note: SCSI channel termination details, if any, appear elsewhere in this
publication.
d. Check for proper backplane jumper configuration.
Note: SCSI channel jumper details, if any, appear elsewhere in this
publication.
e. Check for proper cabling configuration in systems that use hard disk drive
status cables. Reconnect all cables removed in step 1 on page 109.
f. Disconnect one drive at a time attached to the channel identified in step 2a
on page 109; then, restart the computer to determine which drive is causing
the error.
g. Replace the hard disk drive cable.
h. Replace the hard disk drive backplane.
FFFF or other code not listed
1. Place download jumpers on the controller and try to flash the firmware code to
the adapter.
2. Isolate the SCSI subsystem from the controller by disconnecting all hard disk
drive cables attached to the suspect adapter, and restart the computer.
CAUTION:
Do not press F5. Doing so will change the configuration of the server.
If ISPR code is EF10 after disconnecting cables, complete the following steps
until the error is eliminated:
a. Identify which channel is causing the error by reconnecting cables one at a
time and restarting the computer until the error returns.
