HP Instant Capacity (iCAP) manual Glossary, Activate cell

Glossary

activate cell	The process of changing an inactive cell into an active cell. A cell is added to a partition using the
	parmodify and parcreate commands, and is activated through a reboot or reconfig, or
	through cell online activation.
activated core	A core that has been turned on by the Instant Capacity software or during installation. Cores
	are activated with the icapmodify command (or the vparmodify command in an HP-UX
	virtual partition) while HP-UX or OpenVMS is running.
active cell	A cell that is available for use by the software running on the nPartition. This implies that the
	cell’s processors and memory (and I/O, if the cell is attached to an I/O chassis) are all available
	for use by the operating system. An active cell has the following characteristics:
	• It is present and populated.
	• It is powered on.
	• It is assigned to an nPartition.
	• It is released from boot-is-blocked.
active nPartition	An nPartition with at least one active cell.
	See also inactive nPartition.
actual active	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. The number of actual active cores
	for each partition is displayed using the icapstatus command.
	See also intended active.
add-on system	A system that has been converted to an Instant Capacity system. This process is performed by
	an HP service representative.
BCH	Boot console handler. The system firmware user interface that allows boot-related configuration
	changes and operations on PA-RISC systems. For example, BCH provides a way to specify boot
	options and the choice of boot devices. The EFI Boot Manager provides a similar function for
	Intel™ Itanium™-based systems.
BIB	Boot-is-blocked. The state of a cell that is powered on but is not allowed to boot. BIB exists as
	soon as power is enabled to a cell, although the system firmware completes its power-on self-test
	sequence before waiting for BIB to be cleared by the Service Processor. BIB is cleared when the
	Service Processor is told to boot an nPartition. BIB is also cleared when the system firmware
	determines that there is no active Service Processor in a complex.
boot console	See BCH.
handler
boot-is-blocked	See BIB.
bound core	For vPars versions before A.04, a core that can process interrupts for a virtual partition. Bound
	cores cannot be migrated from one virtual partition to another if either of the partitions is
	running. Every virtual partition must have at least one bound core.
cell	A circuit board that contains processors and memory, controlled by a cell controller (CC). A
	cell is the basic building block of an nPartition in a complex.
cell OLA	Cell online activation. The process of changing an inactive cell to an active cell in a booted partition
	without requiring a reboot. If such a cell is attached to a powered-on I/O chassis, then the chassis
	is also activated as part of the cell OLA. Some operating systems do not support online activation
	of cells.
cell online	See cell OLA.
activation
cell-based server	A server in which all cores and memory are contained in cells, each of which can be assigned
	for exclusive use by an nPartition. Each nPartition runs its own instance of an operating system.
codeword	The mechanism used with Instant Capacity software B.06.x and later for adjusting available
	usage rights for system components (RTU codewords), for applying an amount of temporary
	capacity to a system (TiCAP codewords), and for applying sharing rights to a GiCAP system to
