Change the Operational Status of Processors

The psradm command can be used to change the operational status of a processor(s) in a multiprocessor system. The statuses are online, offline and no-intr. Here are a few examples.

Take processors 2 and 3 offline
# psradm -f 2 3

Processors 1 and 2 are not interrupted by I/O processes
# psradm -i 1 2

Bring a specified processor, 3, online
# psradm -n 3

Bring all processors online
# psradm -a -n
