Adding dedicated memory dynamically

You can dynamically add physical memory to a running logical partition that uses dedicated memory using the Hardware Management Console (HMC). This allows you to increase the physical memory available to a logical partition that uses dedicated memory without having to shut down the logical partition.

Before you begin

A Linux® logical partition supports the dynamic addition of memory resources 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 addition of memory resources include 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 website.

To add 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.
