POST (ISPR) error procedures
The Interrupt Status Port Register (ISPR) Error Procedures list errors, symptoms,
and the possible causes. The most probable cause is listed first. Use these
procedures to help you solve ServeRAID problems when servicing the computer. A
complete list of error codes is in Table 16 on page 106.
EF10
Default ISPR. No ISPR error present.
9ZXX thru BZXX
SCSI bus error caused either by cables, termination, defective drives, and
so on.
1. Isolate the error between SCSI subsystem and controller by
disconnecting all SCSI cables from suspect card, and reboot.
CAUTION:
Do not press F5. Doing so changes the configuration.
If an ISPR error is still present, take the following actions until the error
is no longer present:
a. Reseat the controller.
b. Replace the controller.
Note: If the controller detects a configuration change, do not choose
Save Changes. Instead, press F10 to bypass any options to this
effect.
2. If the ISPR error is EF10 after disconnecting cables:
a. Confirm that the identified channel(s) is the cause of the error by
verifying that the error presents itself only when the offending
channel is reconnected.
b. Check termination of identified channel.
c. Check for proper backplane jumper configuration.
d. Check for proper cabling configuration in systems that use DASD
status cables. Reconnect all cables that you disconnected at the
beginning of this procedure.
e. Replace SCSI cable.
f. Replace SCSI backplane.
FFFF (or other code not listed)
1. Isolate between SCSI Subsystem and controller by disconnecting all
SCSI cables attached to the suspect card, and reboot.
CAUTION:
Do not press F5. Doing so changes the configuration.
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. Disconnect one drive at a time attached to identified channel and
reboot each time to determine which drive is causing the problem.
c. Replace SCSI cable attached to the identified channel.
d. Replace backplane attached to the identified channel.
2. If the original ISPR code is still present after disconnecting all SCSI
cables and rebooting, take the following actions until the error is no
longer present:
a. Reseat the controller.
b. Replace the controller.
