ABSTRACT:
Methods and associated structure for migrating storage devices between storage subsystems. A storage device to be removed from a storage subsystem is first “exported” by altering configuration data stored on the storage device. The altered configuration information helps assure that the storage device will be recognized as a foreign device in any storage subsystem into which it is subsequently inserted. Forcing recognition of the storage device as a foreign storage device in any subsystem helps assure predictability of the process of importing the storage device into a new system and helps reduce the risk of data loss when reinserting the storage device into a storage subsystem. Storage devices so migrated may include individual disk drives as well as entire volumes comprising one or more disk drives.
