You can view and change the shared processor pool configuration
by using the Hardware Management Console (HMC).
Procedure
-
In the navigation pane, click Resources.
-
Click All Systems. The All Systems page is
displayed.
-
In the work pane, select a system and click . You can view and change the properties of the system that are listed under the
PowerVM area.
- In the PowerVM area, click Shared
Processor Pool. The Shared Processor Pool page

- From the table, select the shared processor pool that you
want to change.
- From the Select Action list, select Modify.
- Select one of the following options to change the properties
of the selected shared processor pool:
- Pool Name to change the name of the shared
processor pool.
- Pool ID to change the ID of the shared processor
pool.
- Resource Processing Units to change the value
of the reserved processing unit. The reserved processing unit value
is the number of processing units that are reserved for the use of
uncapped partitions within the shared processor pool.
- Maximum Processing Units to change the maximum
value of the processing unit. The maximum processing unit value limits
the total number of processing units that can be used by the partitions
in the shared processor pool.
What to do next
After this task is complete, assign partitions to the
configured shared processor pools. You can assign a partition to a
shared processor pool while creating the partition, or you can reassign
existing partitions from their current shared processor pools to the
shared processor pools that you configured.
When you no longer
want to use a shared processor pool, you can unconfigure the shared
processor pool by using this task to set the maximum number of processing
units and reserved number of processing units to 0.
Before you can unconfigure a shared processor pool, you must reassign
all partitions, which use the shared processor pool, to other shared
processor pools.
