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.

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-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
