HP UX 11i v2 manual Instant Capacity Activation Example Session

Using Instant Capacity to Manage Processing Capacity

Activating Processors

Instant Capacity Activation Example Session

The following example shows you how to activate an additional licensed processor. At the beginning of this activation session, there are a total of 4 processors in the partition; 2 processors are activated and 2 are inactive licensed processors. In this example, 1 additional processor is activated, leaving the partition with 3 active processors and 1 inactive processor:

Example 4-3 Activating an Additional Processor

/usr/sbin/icod_modify -a 1 “Add CPU for new FY: Bill P.”

3 processors are now active, and 3 processors are specified to be active after the next reboot.

Points of interest in the above activation example are:

•The processor activation is instant (that is, a reboot is not required).

•The double-quoted text serves as an audit trail of why the activation was done and who performed it. This information is optional and is written to the Instant Capacity log file (var/adm/icod.log) if provided.

•You do not specify a particular processor to be activated; the software allows one (unspecified) additional processor to be activated.

NOTE	To defer the activation (until the next reboot) add the -Doption to the
	command. See the manpage icod_modify(1M) for details.

The icod_modify command allows you to activate additional processors with the -aoption, or set the total number of active processors with the -soption. For example, the icod_modify command/option -a 2 activates two additional processors in a partition. The icod_modify command/option -s 2 sets the total number of active processors in a partition to 2.

See “Software Application Considerations” on page 69 for details of software application implications when activating additional processors.
