Managing processor resources dynamically

You can dynamically add, remove, and move processor resources to and from running logical partitions using the Hardware Management Console (HMC). This allows you to adjust the processor resources allocated to each logical partition without having to shut down the logical partitions.

The ability to move processor resources dynamically becomes important when you need to adjust to changing workloads. Processor resources can be moved based on the minimum and maximum values that you created for the partition profile. You can move processor resources as long as the processor resources for each logical partition remains within the range specified by the minimum and maximum values for the logical partition. If the managed system uses more than one shared processor pool, you must also ensure that the number of processors used in each shared processor pool is less than or equal to the maximum number of processing units specified for each shared processor pool.
