You can quickly evacuate all volumes from a specified datastore, automatically migrating them to other datastores in the same datastore cluster.

Verify that the specified datastore is part of a datastore cluster.

Verify that Storage DRS is enabled in Not Automation (Manual Mode) for the datastore cluster.

Verify that the volume does not have any snapshots attached. If so, you must detach them first.
