b. Replace the controller
Notes:
a. SCSI channel cable details, if any, appear elsewhere in this publication.
b. The adapter/controller detects a configuration change. Do not choose Save
Changes. Instead, press F10 to bypass any options to this effect.
2. If ISPR error is EF10 after disconnecting cables:
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 4 channels; ServeRAID-4L and -4Lx
controllers have only one channel; and ServeRAID-4M and -4Mx
controllers have 2 channels. ServeRAID-5i controllers have no
channels. The ServeRAID-5i uses the channel connectors of the
server's onboard integrated SCSI controller.

b. Confirm that the channel(s) identified from the error in step 2a is (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
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 98.
f. Disconnect one drive at a time attached to the channel identified in step 2a;
then, reboot to determine which drive is causing the error.
