Pools

This page displays information on the shared processor pools that exist for the selected managed system. You can also change the properties of any shared processor pool except for the default shared processor pool (DefaultPool) by clicking the name of the shared processor pool in the Pool Name column.

There are 64 shared processor pools for each managed system: a default shared processor pool and 63 other shared processor pools. Shared processor pools cannot be created or deleted. Before you can use a shared processor pool other than the default shared processor pool, you must configure the shared processor pool by clicking the name of the shared processor pool in the Pool Name column and setting the maximum processing units of the shared processor pool to a whole number that is greater than zero. After you configure a shared processor pool, you can set partition profiles to use that shared processor pool. When you activate a logical partition, the logical partition uses the shared processor pool from the specified partition profile.

If you no longer want to use a shared processor pool, you must first remove the logical partitions that use that shared processor pool from that shared processor pool. You can do this by moving the logical partitions to other shared processor pools or by shutting down the logical partitions. After you remove all logical partitions from the shared processor pool, you can click the name of the shared processor pool in the Pool Name column and set the maximum processing units of the shared processor pool to zero.

This page displays the following information for each shared processor pool.

Pool Name

This column displays the name of each shared processor pool.

Pool ID

This column displays the pool ID that uniquely identifies each shared processor pool.

Reserved Processing Units

This column displays the number of processing units that are reserved for temporary use by the uncapped logical partitions in each shared processor pool. A logical partition can use reserved processing units only when the logical partition is an uncapped logical partition that requires more than its assigned amount of processor resources. Reserved processing units cannot be used by logical partitions in other shared processor pools. Also, reserved processing units cannot be assigned to a specific logical partition.
The default shared processor pool does not have a reserved number of processing units, because the default shared processor pool automatically uses any processing units that are not used by the other shared processor pools.

Maximum Processing Units

This column displays the maximum number of processing units that the logical partitions in each shared processor pool can use.
The default shared processor pool does not have a maximum number of processing units, because the default shared processor pool automatically uses any processing units that are not used by the other shared processor pools.
