2. Flash the controller with the latest IBM ServeRAID
BIOS/Firmware from the IBM Website.
3. Remove the jumpers.
4. If the error persists, replace ServeRAID controller.
9 XXX thru BXXX (SCSI bus error caused either by
defective drives, termination, etc.)
1. Isolate between SCSI subsystem and controller by
disconnecting all SCSI cables from suspect card, and
reboot.
CAUTION:
Do not press F5. Doing so changes the
customer's configuration.
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
Note
1. Refer to the HMM (Hardware Maintenance
Manual) specific to the system comprising
the SCSI channel for SCSI cable details.
2. The controller detects a configuration
change. Do not choose 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 of the original ISPR code:
Ÿ
ISPR = B1xx = Channel 1
Ÿ
ISPR = B2xx = Channel 2
Ÿ
ISPR = B3xx = Channel 1 and 2
Ÿ
ISPR = B4xx = Channel 3
Ÿ
ISPR = B5xx = Channel 1 and 3
Ÿ
ISPR = B6xx = Channel 2 and 3
Ÿ
ISPR = B7xx = Channel 1, 2 and 3
Ÿ
ISPR = BFxx = Channel not identified
b. Confirm that the channel(s) identified from the
error in step 2a is(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
Refer to the HMM (Hardware Maintenance
Manual) specific to the system comprising
the SCSI channel for termination details.
d. Check for proper backplane jumper
configuration.
