Special Considerations
Instant Capacity Integration with Virtual Partitions
Appendix A 137
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 -d to stop the use of temporary capacity. It is not
necessary to use the “-t” option when using the “-d” option.
