Moving dedicated memory dynamically

You can dynamically move physical memory from one running logical partition that uses dedicated memory to another using the Hardware Management Console (HMC). This action allows you to reassign physical memory directly to a logical partition that uses dedicated memory that needs more physical memory.

Before you begin

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 website.
To move memory to a Linux logical partition that uses an earlier version of these distributions, complete the following steps:
  1. Shut down the Linux logical partition.
  2. Reactivate the logical partition by using a partition profile that specifies a greater amount of memory.
