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 “Chapter . Installing and configuring ServeRAID controllers,” on page
139. 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 “Processor board
component locations” on page 55 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 a..
c. Disconnect one drive at a time attached to channel identified in step a. and
reboot each time to determine which drive is causing the problem.
d. Replace SCSI Cable attached to channel identified in step a..
e. Replace Backplane attached to channel identified in step a..
2. If original ISPR code is still present after disconnecting all SCSI cables and
rebooting, perform the following actions until the error is no longer present:
• Reseat the controller.
• Replace the controller.
ServeRAID
This index supports ServeRAID 3HB Adapters and Controllers. It lists symptoms,
errors, and possible causes.
Note: Do not replace any FRU until you have followed the POST (ISPR) error
procedures (see “ServeRAID POST (ISPR) error procedures” on page 232).
Only replace a ServeRAID 3HB Adapter or controller if ind8icated to do so in
the POST (ISPR) error procedures.
