SCSI error codes
Error code
All SCSI Errors One or more of the
following might be causing the problem:
v A failing SCSI device
(adapter, drive, controller)
v An improper SCSI configuration or SCSI
termination jumper setting
v Duplicate SCSI IDs in the same SCSI
chain
v A missing or improperly installed SCSI
terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable

d. Check for proper backplane jumper configuration.
Note: SCSI channel jumper details, if any, appear elsewhere in this
document.
e. Check for proper cabling configuration in systems that use DASD status
cables. Reconnect all cables removed in step 1 on page 95.
f. Disconnect one drive at a time attached to the channel identified in step 2a
on page 95; then, restart to determine which drive is causing the error.
g. Replace SCSI cable.
h. Replace SCSI backplane.

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:
a.
Identify which channel is causing the error by reconnecting cables one at a
time and restarting until the error returns.
b. Check termination of identified channel in step 2a.
Note: SCSI channel termination details, if any, appear elsewhere in this
document.
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.
d. Replace SCSI cable attached to channel identified in step 2a.
e. Replace backplane attached to channel identified in step 2a.
restarting, perform the following actions until the error is no longer present:
v Reseat the controller
v Replace the controller
FRU/action
1. External SCSI devices must be turned on before you turn on
the server.
2. Make sure that the cables for all external SCSI devices are
connected correctly.
3. If you have attached an external SCSI device to the server, make
sure the external SCSI termination is set to automatic.
4. Make sure that the last device in each SCSI chain is terminated
correctly.
5. Make sure that the SCSI devices are configured correctly.
