About Live Partition Mobility (LPM)
You can use Live Partition Mobility feature from IBM for greater control over the usage of resources in the data center.
Live Partition Mobility enables:
Migration of an entire logical partition from one physical system to another.
The transfer of a configuration from source to destination without disrupting the hosted applications or the setup of the operating system and applications.
A level of reconfiguration that was previously impossible due to complexity or service level agreements that did not allow an application to be stopped for an architectural change.
The migration process can be performed in the following ways:
Inactive migration
The logical partition is powered off and moved to the destination system.
Active migration
The migration of the partition is performed while service is provided, without disrupting user activities. During an active migration, the applications continue to handle their normal workload. Disk data transactions, running network connections, user contexts, and the complete environment are migrated without any loss and migration can be activated any time on any production partition.
