Dynamic movement of shared processor units

 

You can dynamically move shared processors units among logical partitions.

The ability to dynamically move processor power becomes important when you need to adjust to changing workloads. Processors have minimum and maximum values associated with them. These values enable you to establish a range within which you can dynamically move the resource without varying off the logical partition. For shared processors, you can specify a minimum value equal to the minimum amount of processing power needed to support the logical partition. The maximum value must be less than the amount of processing power available on the server. If you change either the minimum or maximum value, it will require you to vary off the partition. To move shared processing power from one logical partition to another, follow these steps:

  1. In iSeries™ Navigator, expand My Connections or your active environment.

  2. Select the primary partition of the server.

  3. Expand Configuration and Service and select Logical Partitions.

  4. Right-click Logical Partition and select Configure Partitions. You are now working in the Configure Logical Partitions window.

  5. From the Configure Logical Partition window, select the partition from which you would like to move shared processing power.

  6. Right-click Shared pool processors and select Move.

  7. Select the units with which you want to work in Display units in -- Processor pool. If you need more information on this field, click Help.

  8. Specify the amount of shared processing power to move in the Amount to move field. This value must be less than the current amount of shared processing power available to the logical partition. The Amount after move values for the source must fall within the minimum and maximum ranges specified for shared processing power for both partitions.

  9. Select the partition to receive the dedicated processors in Move to -- Logical partition.

  10. Click OK to move the shared processing power you specified.
