Operation
Issuing cpuconfig with no parameters displays the config/deconfig status of all processors. A user can
reconfigure CPUs by specifying a CPU number and a state (on or off). If a valid state is entered and is
different from the current state of a CPU, its status changes on the next boot. The last remaining configured
CPU in a system cannot be deconfigured.
