Activating cores
The icapmodify command provides the ability to increase processing capacity instantly by
activating cores with available usage rights in iCAP systems. At any time, any number of inactive
cores with usage rights can be activated, if sufficient usage rights are available.
Whether you are activating or deactivating cores, the icapmodify command adjusts only the
number of dynamic cores, and it does not explicitly identify specific cores.
Activating cores in nPartitions
The iCAP software provides two types of activation:
• Instant (icapmodify command’s default behavior) — activation occurs immediately.
• Deferred (icapmodify -D) — activation occurs after the next reboot of the partition.
Instant activation of cores occurs when the icapmodify command is used with either the -a or
-s option, and the -D option is not specified. If the -s option is used, the number of cores specified
must be greater than the number of currently active cores.
Deferred activation of cores occurs when the icapmodify command is used with both the -D
option and either the -a or -s option. With the deferred option (-D), core activation occurs after
a reboot of the partition. The reboot (and the core activation) can take place at a planned time.
For example, if you activate cores in deferred activation mode and schedule a partition reboot to
occur on the first day of the next month, the cores are activated at that time.
