When the migration completes, the migration status disappears and the volume is  displayed in the target pool, as shown in Figure 11-12. If you choose to import a volume as an image mode volume, the external LUN appears as  an MDisk with an associated image mode volume name and can be listed, as shown in  Figure 11-13. 5. After the migration completes, the image mode volume is automatically deleted, but the  external LUN exists as a managed MDisk in the temporary storage pool. It is unassigned  from the pool and listed as an unassigned MDisk. Later, you can retire the external LUN  and remove it completely from the Storwize V5030 by unmapping the volume at the  external storage and by clicking  Discover Storage  on the Storwize V5030. For more  information about removing external storage, see 11.2.6, “Removing external storage” on  page 621. The volume is also listed in the  System Migration  window because the IBM Storwize  V5030 expects you to migrate these volumes later, as shown in Figure 11-14. At the end of this process, the volume can be mapped to a host.
