iCAP Glossary
Actual active cores: This value is listed in the icapstatus output and displays the current number
of active cores in the partition. In a virtual partition, the count represents the total number of
cores assigned to all virtual partitions.
Core: The actual data-processing engine within a processor. A single processor can have
multiple cores, and a core can support multiple execution threads.
Configured processor: A processor that has been configured at the Boot Console Handler
(BCH) and whose cores are now available for activation.
Deconfigured processor: A processor that has not yet been configured at the boot console
handler (BCH). The iCAP software cannot activate a processor core that is deconfigured.
iCAP component: Also called a component without usage right. An Instant Capacity component
is a core, cell board or memory that is physically installed in an iCAP system but is not
authorized for use.
Inactive cell: A cell that is not available for use by software running on an nPartition. This term
is usually used to describe a cell that has the following status:
 The slot is present and is populated
 Power is enabled
 Boot-is-blocked
 The cell is assigned to an nPartition
Inactive core: A core that either has not yet been activated or that has been turned off by the
Instant Capacity software and returned to the pool of inactive cores. Inactive cores are available
for activation.
Instant Access Capacity (IAC): An amount of temporary capacity included with the purchase
of an Instant capacity Component.
Intended active cores: The number of cores a user requests to be active for a partition by the
Instant Capacity software at the next reconcile operation. A reconcile operation is normally a
reboot, although other actions can trigger a reconcile operation, such as moving cores between
virtual partitions. You adjust the number of intended active cores by using the icapmodify -a, -d,
and -s options. Other commands, such as parmodify and parcreate, can also affect this value.
