-- 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).
