Using Instant Capacity to Manage Processing Capacity
Activating Processors
Chapter 458
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 -D option to the
command. See the manpage icod_modify(1M) for details.
The icod_modify command allows you to activate additional processors
with the -a option, or set the total number of active processors with the
-s option. 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.
