1. Isolate the SCSI subsystem from the controller by disconnecting all hard disk
drive cables from the suspect adapter, and restart the computer.
CAUTION:
Do not press F5. Doing so changes the configuration of the server.
If an ISPR error is still present, perform the following actions until the error is no
longer present:
a. Reseat the controller
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 select 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 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.
