You can dynamically move physical memory from one running
logical partition that uses dedicated memory to
another using the Hardware Management Console (HMC). This allows you to
reassign physical memory directly to a logical partition that uses dedicated memory that needs additional
physical memory.
You cannot dynamically move memory from a running Linux® logical partition.
To remove memory from a Linux logical
partition, you must shut down the Linux logical partition
and reactivate the logical partition using a partition profile that
specifies a lesser amount of memory.
You can dynamically move
memory to a running Linux only
if the following conditions are met:
- A Linux distribution
that supports the dynamic addition of memory resources is installed
on the Linux logical
partition. Distributions that support the dynamic movement of memory
resources include Novell SUSE Linux Enterprise Server 10, and later.
- The DynamicRM tool package is installed on the Linux logical partition.
To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems Web
site.
To move memory to a Linux logical partition
that uses an earlier version of these distributions, you must shut
down the Linux logical
partition and reactivate the logical partition using a partition profile
that specifies a greater amount of memory.
To dynamically move memory from one running logical partition
to another using the HMC,
follow these steps:
- In the navigation pane, open ,
and click the managed system on which the logical partitions are located.
- In the work pane, select the logical partition, click
the Tasks button, and click .
- Enter the amount of physical memory that you want to move
from the logical partition. You can enter the size in a
combination of gigabytes (GB) plus megabytes (MB).
- Select the logical partition to which you want to move
the specified amount of physical memory.
- 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 moves memory dynamically. These settings are not retained after
the move operation is completed.)
- Click OK.
