Changing the memory mode of a logical partition

You can create multiple partition profiles for a logical partition by using the Hardware Management Console (HMC). Some of the partition profiles can specify dedicated memory and some of the partition profiles can specify shared memory. By creating partition profiles that specify both dedicated memory and shared memory for the same logical partition, you can change the memory mode of the logical partition by activating different partition profiles.

1. Create a new partition profile for the logical partition. For instructions, see Creating additional partition profiles.
   • If you plan to change a dedicated memory partition to a shared memory partition, specify the shared memory mode in the new partition profile.
   • If you plan to change a shared memory partition to a dedicated memory partition, specify the dedicated memory mode in the new partition profile.
2. Shut down the logical partition. For instructions, see Shutting down and restarting logical partitions.
3. Activate the logical partition with the new partition profile. For instructions, see Activating a partition profile.
