-- This operation delete the specified gateway volume that you previously
-- created using the CreateStorediSCSIVolume API. For gateway-stored
-- volumes, the local disk that was configured as the storage volume is not
-- deleted. You can reuse the local disk to create another storage volume.
--
-- Before you delete a gateway volume, make sure there are no iSCSI
-- connections to the volume you are deleting. You should also make sure
-- there is no snapshot in progress. You can use the Amazon Elastic Compute
-- Cloud (Amazon EC2) API to query snapshots on the volume you are deleting
-- and check the snapshot status. For more information, go to
-- <http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSnapshots.html DescribeSnapshots>
-- in the /Amazon Elastic Compute Cloud API Reference/.
--
-- In the request, you must provide the Amazon Resource Name (ARN) of the
-- storage volume you want to delete.
