CPU/IO Module Status
The CPU/IO module (0 or 1) started first is managed as primary, and the module started later is
managed as secondary. If one CPU/IO module is disconnected because of the failure and others,
theother module becomes primary.
The CPU/IO module to be started first is selected depending on the primary/secondary status of
modules when the server was shut down the last time. When the server is started for the first time
after power OFF, the CPU/IO module which was powered ON first becomes primary.
