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.
