You can access the External Volumes window to add, migrate, or delete external volumes.

Navigate to the detail window for a storage system, then click External Volumes. The External Volumes window shows external volumes and thin/tiered volumes with data direct mapping enabled. The external volumes are volumes on other storage systems mapped to the storage system. The thin/tiered volumes are DP-VOLs created from Dynamic Provisioning pools or Dynamic Tiering pools.
Note: The following external volumes and thin/tiered volumes with data direct mapping enabled are not displayed:
- The emulation type is not OPEN_V
- Remote command devices
- Volumes using Cache Residency Manager cache
- Pool volumes
- NAS boot volumes
- Quorum disks
- Volumes related to the Namespace for FC-NVMe
On the External Volumes window, the following actions are available:
- Click Open the Logical Devices window in Hitachi Storage Navigator to perform advanced migration functions in Storage Navigator.
- To create external volumes, click the plus sign (+) to open the Create External Volumes window.
- To discover external storage, click Actions > Discover External Storage.
- To migrate external volumes, select attached volumes, then click Actions > Migrate Volumes.
  You can watch a video to see how volume migration is done. The interface may be slightly different, but the steps are the same.
  
  Note: The Assigned to Migration filter can display which volumes are already part of a migration plan. If a volume status is Yes (Unmanaged) the volume is assigned for migration in other storage management tools.
