-- This operation resets all cache disks that have encountered a error and
-- makes the disks available for reconfiguration as cache storage. If your
-- cache disk encounters a error, the gateway prevents read and write
-- operations on virtual tapes in the gateway. For example, an error can
-- occur when a disk is corrupted or removed from the gateway. When a cache
-- is reset, the gateway loses its cache storage. At this point you can
-- reconfigure the disks as cache disks.
--
-- If the cache disk you are resetting contains data that has not been
-- uploaded to Amazon S3 yet, that data can be lost. After you reset cache
-- disks, there will be no configured cache disks left in the gateway, so
-- you must configure at least one new cache disk for your gateway to
-- function properly.
