Load-Balancing Active Processors
Chapter 4 63
Load-Balancing Active Processors
Active processors can be redistributed across any or all partitions of a
hardware-partitionable system if those partitions contain inactive
processors.
For example, consider a system with two partitions:
Partition 1 has 5 active processors and 3 inactive processors
Partition 2 has 8 active processors and 0 inactive processors
You need to add processing power to Partition 1 because of application
demand and you notice that the active processors in Partition 2 are
under utilized.
Deactivating an active processor in Partition 2 decreases the number
of active processors in that partition, and activating one of the processors
in Partition 1 increases the number of active processors in that
partition. The total number of active processors in the complex is the
same at the end of this operation.
IMPORTANT To comply with processor licensing requirements, it is important to
perform the deactivation operation first.
This leaves the following:
Partition 1 now has 6 active processors and 2 inactive processors
Partition 2 now has 7 active processors and 1 inactive processor
Does the redistribution of active processors affect complex-wide
compliance?
No, because you did not change the overall number of active processors
in the complex, assuming it was in compliance prior to the redistribution,
it remains in compliance.
