HP Instant Capacity Version 10.x User Guide (5900-1581, March 2011)

sharing rights A type of codeword applied to a Group Manager to enable the addition of members with Instant
Capacity components to groups. To share resources across groups, you must purchase GiCAP
sharing rights, acquire the GiCAP codeword from the HP Utility Pricing Solutions Portal:
(http://www.hp.com/go/icap/portal), and apply the associated codeword to the Group Manager
system. You purchase at least as many GiCAP sharing rights as the total number of cores without
usage rights across all the potential group members. Members can be added to a GiCAP group
as long as there are sufficient sharing rights available and as long as the grouping rules indicate
hardware compatibility.
See also codeword.
shutdown for
reconfiguration
The process of shutting down an nPartition in such a way that all active cells in the nPartition are
reset with the boot-is-blocked (BIB) attribute. When the operating system that is running on the
nPartition has finished shutting down, these cells begin their power-on self-test sequence and then
wait for BIB to be cleared by the Service Processor. As a result, the nPartition becomes inactive.
On the HP-UX operating system, shutdown for reconfiguration is performed using the shutdown
or reboot commands with the -R and -H (or -RH) options.
See also reboot for reconfiguration.
system A server, nPartition, virtual partition, or virtual machine that is running an instance of an operating
system.
Temporary Instant
Capacity
An HP product that enables customers to purchase prepaid core activation usage rights, for a
specified (temporary) period of time. Temporary capacity is sold in 30 processing-day increments.
Temporary capacity was formerly known as Temporary Instant Capacity on Demand, or TiCOD.
TiCAP See Temporary Instant Capacity.
TiCOD See Temporary Instant Capacity.
unused capacity The difference between actual active and intended active cores. Unused capacity can be a side
effect of using the vparmodify command to deactivate cores without immediately activating
the cores somewhere else. This is usually a transient state because a user typically migrates cores
from one virtual partition to another with a deactivate command followed by an activate command.
However, unused capacity can persist if, for example, a utility such as gWLM ignores an error
status from an activation and leaves the previously deactivated cores in an unassigned state. The
Instant Capacity software always takes unused capacity into account when a request is made to
activate or deactivate cores and attempts to eliminate the discrepancy between intended active
and actual active.
usage rights Usage rights are used by Instant Capacity to activate system components (memory, cell boards,
and cores), and are freed by deactivating components. Usage rights for a complex are adjusted
by the application of a Right to Use (RTU) codeword, and they can be shared between systems
through the use of Global Instant Capacity.
See also RTU.
use-on-next-boot A per-cell flag in the Partition Configuration Data. This flag is used by system firmware during
the process of booting an nPartition. If a cell is assigned to an nPartition and this flag is not set,
then the cell is not activated the next time the nPartition is booted.
Utility Pricing
Solutions Portal
An HP website (http://www.hp.com/go/icap/portal) that gives customers an interface to obtain
codewords for Instant Capacity systems, view asset reports, view Pay per use system-utilization
information and to check other information related to their Utility Pricing Solutions accounts.
virtual machine A software entity provided by HP Integrity Virtual Machines, VMware ESX, or Microsoft Virtual
Server. This technology allows a single server or (with Integrity Virtual Machines) nPartition to act
as a VM Host for multiple individual virtual machines, each running its own instance of an
operating system (referred to as a guest OS). Virtual machines are servers in the HP Virtual Server
Environment (VSE).
virtual partition A software partition of a server, or of a single nPartition, where each virtual partition can run its
own instance of an operating system. A virtual partition cannot span an nPartition boundary.
See also nPartition, virtual machine.
VM See virtual machine.
