b. Confirm that the channels identified from the error in step 2a on page 101
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

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.
