-- 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).
