Processor Instant Capacity on Demand (iCOD)
Managing iCOD Utility (Pay Per Use) on nPartitions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 419
When an nPartition is inactive, all its cells and processors are
inactive and cannot be used until the nPartition is booted (using the
GSP or MP Command menu’s BO command).
• Individual cells that are inactive are not billed for iCOD Utility
purposes, because all processors on inactive cells also are inactive.
This includes unassigned cells, as well as cells that have not
participated in “partition rendezvous” for their assigned nPartition
(for example: newly-added cells or cells that had a “n”
use-on-next-boot value when the nPartition last booted).
Deactivated
Processors
A deactivated processor is one that has been “turned off” by the
nPartition’s iCOD software, perhaps as a result of the
icod_modify -d... command. Deactivated processors can be activated
instantly by using the icod_modify -a... command.
The iCOD software selects which processors are activated and
deactivated and chooses processors based on their physical locations.
For details, see the procedures in Activating and Deactivating Processors
with iCOD on page 412.
Inactive
Processors
An inactive processor is a processor that is in an inactive cell and thus
is at a boot is blocked (BIB) state.
The following examples describe situations where both cells and
processors are inactive (and thus are not subject to iCOD Utility billing):
• All processors on a cell that is not assigned to an nPartition are
inactive.
• All processors on a cell that did not participate in “partition
rendezvous” for its nPartition are inactive.
You can make a cell inactive either by unassigning it from an
nPartition, or by setting the cell’s use-on-next-boot value to “n”
(meaning: do not use the cell) and rebooting the cell’s nPartition.
• All processors on cells that are assigned to an inactive nPartition are
inactive.
You can make all processors in an nPartition inactive by resetting
the nPartition to the ready for reconfig state. In an inactive
nPartition, all cells are inactive and thus all processors on cells in
the nPartition are inactive.
