You can dynamically remove physical memory from a running AIX®, IBM® i, or Virtual I/O Server logical partition that uses dedicated memory using the Hardware Management Console (HMC). This allows you to
reassign the physical memory to other logical partitions that use dedicated memory.
You cannot dynamically remove memory from a running Linux® logical partition.
To remove memory from a Linux logical
partition, you must shut down the logical partition and reactivate
the logical partition using a partition profile that specifies a lesser
amount of memory.
To dynamically remove memory from a running logical partition
using the HMC,
follow these steps:
- In the navigation pane, open ,
and click the managed system on which the logical partition is located.
- In the work pane, select the logical partition, click
the Tasks button, and click .
- In the Assigned Memory field, enter
the total amount of physical memory that you want to assign to the
logical partition. You can enter the size in a combination
of gigabytes (GB) plus megabytes (MB).
- Adjust the settings in the Options area
if necessary. You might need to increase the value in
the Timeout (minutes) field to allow enough
time for the HMC to
complete the operation. (These settings relate to how the managed
system removes memory dynamically. These settings are not retained
after the removal is completed.)
- Click OK.
