b. Confirm that the channels identified from the error in step 2a on page 107
are the cause of the error by verifying that the error presents itself only
when the offending channel is reconnected.
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

e. Check for proper cabling configuration in systems that use hard disk drive
status cables. Reconnect all cables removed in step 1 on page 107.
f. Disconnect one drive at a time attached to the channel identified in step 2a
on page 107; then, restart to determine which drive is causing the error.

Attention: Do not press F5. Doing so changes the computer 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.
restarting, perform the following actions until the error is no longer present:
