c. Check termination of 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 94.
f. Disconnect one drive at a time attached to the channel identified in step 2a
on page 94; then, restart to determine which drive is causing the error.
g. Replace SCSI cable.
h. Replace SCSI backplane.
FFFF or other code not listed
1. Place download jumpers on the controller and try to flash the firmware code to
the card.
2. Isolate between SCSI subsystem and controller by disconnecting all SCSI
cables attached to the suspect card, and restart.
Attention: Do not press F5. Doing so changes the server configuration.
If ISPR code is EF10 after disconnecting cables, follow these steps until the
error is eliminated:
a. Identify which channel is causing the error by reconnecting cables one at a
time and restarting until the error returns.
b. Check termination of identified channel in step 2a.
Note: SCSI channel termination details, if any, appear elsewhere in this
publication.
c. Disconnect one drive at a time attached to channel identified in step 2a and
restart each time to determine which drive is causing the problem.
d. Replace SCSI cable attached to channel identified in step 2a.
e. Replace backplane attached to channel identified in step 2a.
3. If original ISPR code is still present after disconnecting all SCSI cables and
restarting, perform the following actions until the error is no longer present:
v Reseat the controller
v Replace the controller
