def reset_cache(GatewayARN=None):
    """
    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. This operation is only supported in the cached volume,tape and file gateway architectures.
