Processor Instant Capacity on Demand (iCOD)

Managing iCOD Utility (Pay Per Use) on nPartitions

HP System Partitions Guide: Administration for nPartitions, rev 5.1

To put an nPartition in the inactive, ready for reconﬁg state: if

HP-UX is running use the shutdown -R -H command, or if at the

Boot Console Handler (BCH) interface use the RECONFIGRESET

command.

None of an inactive cell’s resources (processors, memory, or any I/O

connected to the cell) are available for use in an nPartition. For the cell’s

processors and other hardware resources to be used, the cell must be

assigned and active in an nPartition.

Deconﬁgured

Processors

A deconﬁgured processor is a processor that has been made

unavailable for use by its nPartition through settings enabled by Boot

Console Handler (BCH) menu commands.

You can deconﬁgure processors using the BCH Conﬁguration menu’s

CPUCONFIG command. Also use this command to conﬁgure processors

that have been deconﬁgured.

Using BCH commands to conﬁgure and deconﬁgure processors requires

rebooting the nPartition in which the processors reside. For this reason

deconﬁguring processors is not the recommended method of making

processors inactive for iCOD purposes.

Instead, the recommended method is to deactivate processors using the

icod_modify -d... HP-UX command, which can instantly make

processors deactivated and activated without rebooting.
