Diagnosis
Diagnose the system board.
The specified system board must be unconfigured from the
domain or the domain in which the system board is
configured must be powered off.
Note – (1) Memory mirroring requires twice the amount of memory domain used
for operation. If the PSB is a Quad-XSB type in M8000/M9000 servers, memory
mirroring cannot be used. In M4000/M5000 servers, memory mirroring can be used
regardless of whether the system board is a Uni-XSB or Quad-XSB.
Note – (2) The add/delete/replace operations are done by field engineers (FEs). If a
command is performed, the maintenance guidance is displayed. FEs will use the
device check, select, add, and delete operations in the guidance window. For
information about how to handle and operate these devices, see the Service Manual
for your server and any manual written for FEs.
