Probably the cache settings you are choosing are not supported. Check the battery status. If the battery has failed or the charge level is not high enough the controller will disable the cache.
Try reseating the cache module. Be careful, you must shutdown and power off the server, remove the P440ar, remove the battery and then reseat the cache module. Put everything back in reverse order and ensure all components are firmly inserted.
