MAP 0200: Processor IPL Problem
009 (continued)
Does device list include “hdisk...” and does diagnostics pass for “hdisk...”?
Yes No
010
Problem detected.
– Note any diagnostic results before continuing.
– Put the circuit breaker(s) at the front of the processor node in the Off (‘0’) position.
– Go to Step 011.
011
– Ensure that the processor node is in service position.
– Use the following prioritized table to continue service:
Priority Condition Action
1 Ÿ Device list does not include any
device(s) like “scsi0” or “ascsi0”.
Ÿ
Diagnostics fail for device(s) like
“scsi0” or “ascsi0”.
1. If diagnostics indicate the cause of failure,
perform service based on the diagnostics results,
then go to Step 012.
2. Replace I/O planar.
3. Go to Step 012.
2 Ÿ Device list does not include any
SCSI MCAs like “ascsi...” or
“vscsi...”.
Ÿ Diagnostics fail for SCSI MCAs
“ascsi...” or “vscsi...”.
1. If diagnostics indicate the cause of failure,
perform service based on the diagnostics results,
then go to Step 012.
2. Replace SCSI MCA card.
3. Go to Step 012.
3 Ÿ Device list does not include the
problem “hdisk...”
Ÿ
Diagnostics fail for the problem
“hdisk...”.
Ÿ
“hdisk missing”
1. Check the SCSI bus cables (and SCSI riser card
if present) for a loose connection or damaged
cable, especially at this disk. Also check for a
loose or missing terminator. (For 604 and 604e
high nodes, refer to the media drawer diagram in
"Removing the 604 or 604e High Node DASD" in
IBM RS/6000 SP: Maintenance Information,
Volume 3, Locations and Service Procedures
showing the SCSI path and power cable.)
2. Check the power cables for this disk at both ends
for a loose connection or damaged cable.
3. Check DASD addressing. Refer to Adapters,
Devices, and Cable Information for Micro-Channel
Bus Systems, SA38–0533, for the required
jumper information.
4. If a cable problem is found, repair or replace
cable, then go to Step 012.
5. If no cable problem is found, replace disk, then go
to Step 012.
4 Diagnostics pass for the problem
“hdisk...”. Go to Step 013 on page 1-97.
012
Component repaired or replaced.
– Put the circuit breaker(s) at the front of the processor node in the On (‘1’) position.
