	//    MAY call `CreateVolume` again, with the same name, to ensure the
	//    volume exists and to retrieve the volume's `volume_id` (unless
	//    otherwise prohibited by "CreateVolume Errors").
	// 2) Suggested name - Some storage systems allow callers to specify

	//    use this name as the identifier for the new volume.
