MAP 0100: Start of Service Call
Priority Condition Action
10 One of the following problems
detected by the customer or cus-
tomers' EREP program:
Ÿ
I/O adapter problem (other than
BMCA).
If this is a SPS adapter problem
in a 135 MHz wide node at PSSP
level 2.3 or below, first check to
ensure that the SPS adapter is
plugged into an I/O bus 0 slot
(preferably slot 0/4).
Ÿ If this is a 332 MHz SMP node,
ensure the SPS adapter cable is
plugged into port P0.
Ÿ
Memory and/or processor
problem (for 604e high nodes,
ensure that memory DIMM
types are not mixed on indi-
vidual memory cards or on the
node).
Ÿ SCSI/HDISK or other device
problems. (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 Infor-
mation, Volume 3, Locations and
Service Procedures showing the
SCSI path and power cable.)
1. Check the processor node for any additional
errors reported. (Look in errpt -a | pg on the
affected node.) If possible, run diag -a to check
for missing or additional devices. If any SRN is
logged, find the equivalent RS/6000 model in
Table 1-6 on page 1-33. Then locate the SRN
table in
Diagnostic Information for Micro Channel
Bus Systems (SA38-0532). or Diagnostic Informa-
tion for Multiple Bus Systems (SA38-0509).
2. Have the customer remove the processor node
from the active configuration and SHUTDOWN the
node.
3. IPL the processor node in SERVICE mode. Refer
to "Running Diagnostics in a Processor Node" in
IBM RS/6000 SP: Maintenance Information,
Volume 3, Locations and Service Procedures.
4. Run diagnostics against the suspected card. Refer
to Diagnostic Information for Micro Channel Bus
Systems (SA38-0532) or Diagnostic Information
for Multiple Bus Systems (SA38-0509) and the
Adapters, Devices and Cable Information
(SA38-0533).
Refer to RS/6000 SP: Maintenance Information,
Volume 3 for processor node locations and
removal and replacement procedures, or
RS/6000
SP: Maintenance Information, Volume 4 for part
numbers, as required. (For 604 or 604e high
processor nodes, consult the
7015 Models R30,
R40, and R50 CPU Enclosure Installation and
Service Guide and 7015 Supplemental
Information.)
Note: When diagnosing problems on 604 or
604e high nodes, place IPL in "long IPL
boot". (See “MAP 0280: 604 or 604e High
Node Minimum Configuration” on
page 1-145.)
5. If no problem is found and no service was taken,
the problem may be in the software or attached
hardware.
6. If parts were just repaired or replaced, go to Step
001 on page 1-4.
7. Return processor node to NORMAL mode. Power
off/on the processor node to IPL.
8. Go to “MAP 0570: End of Call” on page 1-357.
11 Processor node or switch assembly is
not recognized by system monitor:
Ÿ Display shows an empty box for
this processor node or switch
assembly.
Go to “MAP 0120: Supervisor Bus Problem” on
page 1-19 to service this processor node or switch
assembly.
