Dynamically managing memory

You can use the Integrated Virtualization Manager to change the amount of memory that a running logical partition uses.

1. In the navigation area, select View/Modify Partitions under Partition Management. The View/Modify Partitions page is displayed.
2. Select the logical partition for which you want to change the memory settings.
3. From the Tasks menu, click Properties. The Partition Properties page is displayed.
4. On the General tab, verify that Yes is the value for Memory DLPAR Capable. You might need to click Retrieve Capabilities to verify this value. If No is the value for Memory DLPAR Capable, then you cannot dynamically change the memory settings for the logical partition while the logical partition is active.
5. Select the Memory tab.
6. Specify new values in the Pending column for the memory settings that you want to change. If the client logical partition uses shared memory, you can dynamically change the Pending values, including the memory weight. However, you cannot change the memory mode of a running logical partition.
   Note: For logical partitions that use either dedicated memory or shared memory, you can change the minimum and maximum memory values only while the logical partition is not running.
7. Click OK. The management partition synchronizes the current assigned value with the pending assigned value. Synchronization can take several seconds to complete. You can perform other tasks on the system while the management partition is synchronizing the current and pending values.
