-- | This operation configures one or more gateway local disks as working storage
-- for a gateway. This operation is supported only for the gateway-stored volume
-- architecture. This operation is deprecated method in cached-volumes API
-- version (20120630). Use AddUploadBuffer instead.
--
-- In the request, you specify the gateway Amazon Resource Name (ARN) to which
-- you want to add working storage, and one or more disk IDs that you want to
-- configure as working storage.
