HP UX 11i v2 manual Temporary Capacity and Virtual Partitions

Special Considerations

Instant Capacity Integration with Virtual Partitions

WARNING	The icod_modify command should not be used in a compatible
	virtual partition environment to deactivate processors if
	processor sets (Psets) are being used. The icod_modify command
	utilizes the vparmodify command which does not recognize Psets.
	Using the icod_modify command to deactivate a processor may
	cause an unintended processor to be removed from a Pset.
	When you execute the icod_modify command to activate a processor, it
	determines how many processors are available for activation. If enough
	processors are available to meet the request, the appropriate
	vparmodify command is executed, and the proper number of unbound
	processors are added to the local virtual partition.
	Whether you are activating or deactivating processors, the (appropriate)
	vparmodify command adjusts only the number of unbound processors,
	and it does not explicitly identify specific processors, or affect the
	number of bound processors.
	Temporary Capacity and Virtual Partitions
	If temporary capacity is being consumed in any virtual partition
	environment (having been previously authorized using icod_modify -a
	n -t), deactivating a processor with the vparmodify command
	temporarily reduces the consumption of temporary capacity. A
	subsequent processor activation using vparmodify increases
	consumption of temporary capacity, assuming that this activation
	results in there being more active processors than licensed processors.
	Use icod_modify -dto stop the use of temporary capacity. It is not
	necessary to use the “-t” option when using the “-d” option.
