HP Instant Capacity on Demand (iCOD) for nPartitions

When an nPar is inactive all its cells and processors are inactive and
cannot be used until the nPar 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 nPar (for
example: newly added cells or cells that had a “n” use-on-next-boot
value when the partition last booted).
Deactivated
Processors
A deactivated processor is one that has been “turned off” by the
nPar’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 refer to the procedure for activating and deactivating iCOD
processors.
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 nPar are inactive.
• All processors on a cell that did not participate in “partition
rendezvous” for its nPar are inactive.
You can make a cell inactive either by unassigning it from an nPar, 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 nPar are
inactive.
You can make all processors in an nPartition inactive by resetting the
nPar to a ready for reconfig state. In an inactive nPar, all cells are
inactive and thus all processors on cells in the nPartition are inactive.
