Live Partition Mobility of virtual log devices

When a client logical partition is moved from one host system to another during Live Partition Mobility, new virtual log devices are created on the destination Virtual I/O Server (VIOS).

When you do not use Shared Storage Pools, these new virtual logs are independent of the virtual logs on the source VIOS. The configuration data of the source virtual log without the log file content is copied to the destination virtual log during migration. After migration, the source virtual log is placed in the migrated state to indicate that the virtual log is no longer active on the system and that it has been moved to another system. If you use a migration operation to move the client logical partition back to the original host system, and you select the original VIOS to host the virtual logs of the logical partition, the existing virtual log is moved back to the enabled state.
