IBM 866251Y - Netfinity 5500 M20, Hardware Maintenance Manual, Page: 324 / 386

Note
Refer to the HMM (Hardware Maintenance
Manual) specific to the system comprising
the SCSI channel for jumper details.
e. Check for proper cabling configuration in
systems that use DASD status cables.
Reconnect all cables removed in step 1 above.
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.
g. Replace SCSI cable.
h. Replace SCSI backplane.
EF10 (Default ISPR)
1. No ISPR error present.
2. Controller is probably functioning properly.
Do not
replace system board unless you have run the
controller's diagnostics and you get an error message.
If you do not get an error message, assume it is
functioning properly.
3. Refer to “ServeRAID Startup Messages” on
page 318. Note the resulting BCS and or ECS Error
codes, and see the FRU actions respective to those
codes. (EF10 is a default code for ISPR indicating
that there is no ISPR error present.)
EFFE (Firmware code corrupted or download jumpers are
in place.)
1. Verify download jumpers are in their default locations.
See “System board jumpers” on page 280 for jumper
locations.
2. If download jumpers are not in place and error still
persists, then flash the controller firmware with the
jumpers in place; then remove the jumpers.
3. If error persists after step 2, replace the controller or
the system board with integrated controller.
FFFF or other code not listed
1. Isolate between SCSI subsystem and controller by
disconnecting all SCSI cables attached to the suspect
controller and reboot. If ISPR code is EF10 after
disconnecting cables, follow the steps below until the
error is eliminated:
a. Identify which channel is causing the error by
reconnecting cables one at a time and rebooting
until the error returns.
b. Check termination of identified channel in step
1a.
