2.2.12 System Board Configuration
System board configuration settings are used to specify XSB division information for
a physical system board (PSB) and configure the memory mirror mode.
Note – Before dividing a PSB into XSBs or changing the memory mirror mode,
make sure that the PSB is not assigned to any domain (system board pool state;
unassign).
