controllers have 2 channels. ServeRAID-5i controllers have no
channels. The ServeRAID-5i uses the channel connectors of the
onboard integrated SCSI controller.

b. Confirm that the channels identified from the error in step 2a on page 88 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 DASD status
cables. Reconnect all cables removed in step 1 on page 88.
f. Disconnect one drive at a time attached to the channel identified in step 2a
on page 88; then, restart to determine which drive is causing the error.
g. Replace SCSI cable.
h. Replace SCSI backplane.

1. Place download jumpers on the controller and try to flash the firmware code to
the card.
2. Isolate between SCSI subsystem and controller by disconnecting all SCSI
cables attached to the suspect card, and restart.
Attention: Do not press F5. Doing so changes the server configuration.
If ISPR code is EF10 after disconnecting cables, follow these steps until the
error is eliminated:
