-- This operation configures one or more gateway local disks as cache for a
-- cached-volume gateway. This operation is supported only for the
-- gateway-cached volume architecture (see
-- <http://docs.aws.amazon.com/storagegateway/latest/userguide/StorageGatewayConcepts.html Storage Gateway Concepts>).
--
-- In the request, you specify the gateway Amazon Resource Name (ARN) to
-- which you want to add cache, and one or more disk IDs that you want to
-- configure as cache.

-- /See:/ <http://docs.aws.amazon.com/storagegateway/latest/APIReference/API_AddCache.html AWS API Reference> for AddCache.
