Moving Memory from One Logical Partition to Another

Use this procedure to use the Hardware Management Console (HMC) to move memory from one partition to another without rebooting the partition's operating system.

To move memory from one active partition to another without rebooting either partition, do the following:

  10. Select the memory amount you want to move from this partition.
    11. Note:
    The number you are removing cannot make the remaining memory amount be less than the minimum number specified in this partition's active profile. To learn more about the resources being used by the activated partition, select the Details tab of this partition's Properties folder.
  11. Select the name of the partition to which you want to move the memory.
  12. In the Task timeout field, select the number of minutes you want the system to wait before it stops the memory dynamic reconfiguration task.
