-- | This operation configures one or more gateway local disks as upload buffer
-- for a specified gateway. This operation is supported for both the
-- gateway-stored and gateway-cached volume architectures.
--
-- In the request, you specify the gateway Amazon Resource Name (ARN) to which
-- you want to add upload buffer, and one or more disk IDs that you want to
-- configure as upload buffer.
