Live Partition Mobility

Live Partition Mobility, a component of the PowerVM® Enterprise Edition hardware feature, provides the ability to move AIX®, IBM® i, and Linux logical partitions from one system to another. The mobility process transfers the system environment that include the processor state, memory, attached virtual devices, and connected users.

Active partition mobility allows you to move AIX, IBM i, and Linux logical partitions that are running, including the operating system and applications, from one system to another. The logical partition and the applications running on that migrated logical partition do not need to be shut down.

Inactive partition mobility allows you to move a powered off AIX, IBM i, or Linux logical partition from one system to another.

You can use the Hardware Management Console (HMC), the IBM Systems Director Management Console (SDMC), or the Integrated Virtualization Manager (IVM) to move an active or inactive logical partition from one server to another. You cannot migrate a mobile partition from a system that is managed by an HMC to a system that is managed by IVM. Similarly you cannot migrate a mobile partition from a system that is managed by IVM to a system that is managed by an HMC.

Because the HMC and SDMC always move the last activated profile, an inactive logical partition that has never been activated cannot be moved. For inactive partition mobility, you can either select the partition state defined in the hypervisor, or select the configuration data defined in the last activated profile on the source server. Use the IVM to move a logical partition that has never been activated.

You cannot perform Live Partition Mobility that is both bidirectional and concurrent. For example:
  • When you are moving a mobile partition from the source server to the destination server, you cannot move another mobile partition from the destination server to the source server.
  • When you are moving a mobile partition from the source server to the destination server, you cannot move another mobile partition from the destination server to some other server.
