HP UX 11i v2 manual Deactivation Example Session for, Hardware-partitionable Systems

Using Instant Capacity to Manage Processing Capacity

Deactivating Processors

	Deactivation Example Session for
	Hardware-partitionable Systems
	The following example shows you how to deactivate an active processor.
	At the beginning of this deactivation session, there are a total of 4
	processors in the partition; 3 processors are active and 1 is inactive. In
	this example, 1 active processor is deactivated, leaving the partition with
	2 active processors and 2 inactive processors. As with activation, you do
	not specify a particular processor to be deactivated. You specify only a
	number of processors to be deactivated.
Example 4-4	Deactivating an Active Processor
	/usr/sbin/icod_modify -d 1
	2 processors are now active, and 2 processors are specified to
	be active after the next reboot.
NOTE	In the above deactivation example, the processor deactivation is instant
	(that is, does not require a reboot). To defer the deactivation (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 deactivate processors with the
	-doption, or set the total number of active processors with the -soption.
	For example, the icod_modify -d 1 command/option deactivates 1
	additional processor in a partition. The icod_modify -s 2
	command/option sets the total number of active processors in a partition
	to 2.
