Learn about the Integrated Virtualization Manager (IVM) and how you can use it to move an active or inactive logical partition from one server to another server.
When you install the Virtual I/O Server on a system that is not managed by an HMC or an IBM® BladeCenter blade server, the Virtual I/O Server becomes the management partition and provides the IVM for systems management. The IVM provides a web-based and command-line interface that you can use to migrate a logical partition from one system to another.
The Migration task on the IVM helps you validate and complete a partition migration. The IVM determines the appropriate type of migration to use based on the state of the logical partition. If the logical partition is in the Running state, then the migration is active. If the logical partition is in the Not Activated state, then the migration is inactive. Before migrating your logical partition, conduct a validation check to ensure that your migration will complete successfully.
The following table describes the services that the management partitions on the source and destination servers provide to the mobile partition (and other client partitions).
| Service provided by the management partitions | Description |
|---|---|
| Server partition | The
management partition on the source server
and the management partition on the destination server must provide
storage and networking resources to the mobile partition so that the
mobile partition has access to the same storage from both the source
and destination servers. Where possible, partition mobility preserves
the following configuration attributes:
|
| Mover service partition | For active partition mobility, the management partition on the source server and the management partition on the destination server automatically become mover service partitions. During active partition mobility, the mover service partitions transfer the mobile partition from the source server to the destination server as follows:
|
| Paging VIOS partition | A VIOS logical partition that is assigned to the shared memory pool (hereafter referred to as a paging VIOS partition) provides access to the paging space devices for the logical partitions that use shared memory. The management partition on the source server is the paging VIOS partition on the source server, and the management partition on the destination server is the paging VIOS partition on the destination server. When you validate a mobile partition (that uses shared memory) for active partition mobility, the IVM checks that the paging storage pool on the destination system contains an available paging space device that meets the size requirements of the mobile partition. If the paging storage pool does not contain such a device, the IVM checks that the paging storage pool has enough space for it to automatically create a paging space device that meets the size requirements of the mobile partition. |
