MAP 0230: Wide Processor Node Control
Attention: The processor node(s) must be removed from active configuration before continuing. If
processor node(s) is/are off, continue; otherwise, ask customers to initiate shutdown procedure and
power-off processor node(s) from the control workstation, or defer maintenance until all jobs are com-
pleted. Powering off a processor node(s) in a parallel environment will cause all jobs to flush from the
queue and switch initialization to rerun.
Attention: Servicing a processor node with the High Performance Switch (HiPS) feature or Scalable
POWERparallel Switch (SPS) feature installed, will impact the entire switch network, unless the processor
node has already been powered off (or fenced) and/or the switch data cable has been disconnected.
Refer to "Service Position Procedures" in
IBM RS/6000 SP: Maintenance Information, Volume 3, Locations
and Service Procedures for placing or removing processor node(s) in/from service position.
Refer to "Viewing Switch Partitions" in
IBM RS/6000 SP: Maintenance Information, Volume 3, Locations
and Service Procedures for locating and fencing/unfencing nodes within a switch partition.
001
Processor node problem detected by customer or CE.
– Use the following table to continue service:
Condition
Action
3-digit LEDs displayed but missing segments or
remain blank
Go to Step 036 on page 1-117.
Node will not reset
Mode switch problem—problem setting NORMAL,
SECURE, or SERVICE.
Go to Step 002.
No response from TTY console
Go to Step 026 on page 1-114.
Yellow or green LEDs on node will not light.
Go to Step 042 on page 1-118.
002
Node will not reset or mode switch problem.
– Check with customer to make sure this processor node is not in the current active configuration. If
processor node is
not operational and actively working at this time, continue service. If it is operational
and actively working, schedule a time convenient for the customer.
– From the control workstation, open the node front panel display.
– Make note of the mode switch position for this processor node.
– Set mode switch to something other than that recorded above.
– If not already there, set the mode switch to SERVICE.
Note: Do NOT recycle node power until reset fault is verified
.
Does the mode switch fail to toggle?
Yes No
003
– Problem not related to mode switch.
