-- | This operation returns a description of the gateway volumes specified in the
-- request. This operation is supported only for the gateway-cached volume
-- architecture.
--
-- The list of gateway volumes in the request must be from one gateway. In the
-- response Amazon Storage Gateway returns volume information sorted by volume
-- Amazon Resource Name (ARN).
