Active cores can be redistributed across any or
all partitions of a hardware-partitionable system if those partitions
contain inactive cores.
For example, consider a system with two partitions:
Partition 1 has 5 active cores and 3 inactive cores
Partition 2 has 8 active cores and 0 inactive cores
You need to add processing power to Partition 1 because of application demand and you
notice that the active cores in Partition 2 are under-utilized.
Deactivating an active core in Partition 2 decreases the number of active cores in that partition, and activating
one of the cores in Partition 1 increases
the number of active cores in that partition. The total number of
active cores in the complex is the same at the end of this operation.

 | IMPORTANT: To remain in compliance, it is important to perform
the deactivation operation first. |

This leaves the following:
Partition
1 now has 6 active cores and 2 inactive cores
Partition
2 now has 7 active cores and 1 inactive core
Does the redistribution of active cores
affect compliance?
No, because you did not change the overall number
of active cores in the complex. If it was in compliance prior to the
redistribution, it remains in compliance. You should ensure that you
have proper licensing for all HP and third party software when performing
load balancing.
