Changing a shared processor pool

You can view and change the shared processor pool configuration by using the Hardware Management Console (HMC).

  1. Choose one of the following navigation options depending on the interface type of the Hardware Management Console (HMC):
    • If you are using an HMC Enhanced interface, complete the following steps:
      1. In the navigation pane, expand Systems Management > Servers.
      2. In the work pane, select the server on which you want to view and change the shared processor pool configuration.
      3. Select Manage PowerVM by using one of the following options to open the PowerVM Configuration page:
        • Click the menu next to the server name and select Manage PowerVM.
        • In the work pane, click Manage PowerVM.
    • If you are using an HMC Enhanced+ interface, complete the following steps:
      1. In the navigation pane, click the Resources icon The icon represents the Resources function of the HMC.
      2. Click All Systems. The All Systems page is displayed.
      3. In the work pane, select a system and click Actions > View System Properties. You can view and change the properties of the system that are listed under the PowerVM area.
  2. In the PowerVM area, click Shared Processor Pool. The Shared Processor Pool page opens.
  3. From the table, select the shared processor pool that you want to change.
  4. From the Select Action list, select Modify.
  5. 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.

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.
