Changing the Active Memory Expansion factor for AIX logical partitions

You can dynamically change the Active Memory™ Expansion factor for an AIX® logical partition by using the Hardware Management Console (HMC). Changing the Active Memory Expansion factor for a logical partition increases or decreases the desired degree of expanded memory capacity for the logical partition.

You can change the Active Memory Expansion factor for logical partitions that use dedicated memory and logical partitions that use shared memory.

The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

For more information about changing the memory settings when the HMC is at version 8.7.0, or later, see Changing memory settings.

To dynamically change the Active Memory Expansion factor for a logical partition, complete the following steps by using the HMC:
  1. In the navigation pane, open Systems Management > Servers, and click the managed system on which the logical partition is located.
  2. In the contents pane, select the logical partition for which you want to change the Active Memory Expansion factor.
  3. From the Tasks menu, select Dynamic Partitioning > Memory > Add or Remove.
  4. In the Active Memory Expansion field, enter a value between 1.00 and 10.00.
  5. Click OK.
