a. Identify which channel is causing the error by the second digit (Z) of the
original ISPR code as indicated in the following table:
Note: ServeRAID-4H controllers have four channels; ServeRAID-4L and
-4Lx controllers have only one channel; and ServeRAID-4M and -4Mx
controllers have two channels. ServeRAID-5i controllers have no
channels. The ServeRAID-5i uses the channel connectors of the
integrated SCSI controller of the server.

b. Confirm that the channels identified from the error in step 2a 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 93.
f. Disconnect one drive at a time attached to the channel identified in step 2a;
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.
