Adding and removing logical memory dynamically to and from a shared memory partition
You can dynamically add and remove logical memory to and from a running logical partition that uses shared memory (hereafter referred to as a shared memory partition) using the Hardware Management Console (HMC). This allows you to increase and decrease the logical memory assigned to the shared memory partition without having to shut down the logical partition.
Before you begin
A Linux® shared memory partition supports the dynamic addition and removal of logical memory resources only if the DynamicRM tool package is installed on the Linux shared memory partition. To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems website.
To dynamically add and remove logical memory to and from a running logical partition using the HMC, you must be a super administrator, service representative, product engineer, or operator of the HMC.
