-- | Retrieves an archived virtual tape from the virtual tape shelf (VTS) to a
-- gateway-VTL. Virtual tapes archived in the VTS are not associated with any
-- gateway. However after a tape is retrieved, it is associated with a gateway,
-- even though it is also listed in the VTS.
--
-- Once a tape is successfully retrieved to a gateway, it cannot be retrieved
-- again to another gateway. You must archive the tape again before you can
-- retrieve it to another gateway.
