The time that it takes for the migration process to complete depends on the size of the  volume. To monitor the status of the migration navigate to  Monitoring  Background  Tasks , as shown in Figure 7-47. After the migration task completes, the  Background Tasks  menu displays a  Recently  Completed Task , as shown in Figure 7-48. In the  Volumes  Volumes  menu, the volume copy is now displayed in the target storage  pool, as shown in Figure 7-49. The volume copy is migrated without any host or application downtime to the new storage  pool.  Another way to migrate single-copy volumes to another pool is to use the volume copy  feature. Note:  Migrating a volume between storage pools with different extent sizes is  not supported. If you need to migrate a volume to a storage pool with a different extent size,  use the volume copy feature instead. 308  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1 Figure 7-49 Volume copy after migration Figure 7-48 Migration complete Figure 7-47 Migration progress
