20120254553 | ZONE GROUP REASSIGNMENT USING STORAGE DEVICE SIGNATURES - A method and apparatus for assigning zone groups to a storage enclosure is disclosed. When a storage enclosure is added to a switch in a fabric, a signature of the storage enclosure will be created from the storage devices loaded in that enclosure.
