-- | This operation creates a volume on a specified gateway. This operation is
-- supported only for the gateway-stored volume architecture.
--
-- The size of the volume to create is inferred from the disk size. You can
-- choose to preserve existing data on the disk, create volume from an existing
-- snapshot, or create an empty volume. If you choose to create an empty gateway
-- volume, then any existing data on the disk is erased.
--
-- In the request you must specify the gateway and the disk information on
-- which you are creating the volume. In response, AWS Storage Gateway creates
-- the volume and returns volume information such as the volume Amazon Resource
-- Name (ARN), its size, and the iSCSI target ARN that initiators can use to
-- connect to the volume target.
