Stopping temporary capacity usage
To decrease the use of temporary capacity or to stop using it entirely, deactivate the appropriate
number of cores.
IMPORTANT: Do not use the icapmodify -t command when deactivating cores.
Temporary capacity is not used when the number of active cores is equal to or less than the number
of cores with usage rights, across the complex. To deactivate one or more cores in a partition on
the operating system, use the following:
icapmodify -d <number>
