2.2.12 System Board Configuration
System board configuration settings are used to specify XSB division information for
a PSB and configure the memory mirror mode.
System board configuration is a function which is available on the
M4000/M5000/M8000/M9000 servers. In the M3000 server, the system board has
been configured by default and you cannot change the settings. However, you can
refer to the system board information
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).
TABLE 2-25 lists a term used in system board configuration.
TABLE 2-26 lists the settings and the corresponding shell commands.
