EMC NAS Service not starting

After a recent planned power outage I cannot ping or putty into my control station or http into my celerra management software. I can however hyperterminal into the control station. I got a message telling me tath EMC NAS Service could not start due to a couple of reasons: 1) The service is still starting please try agin in 15 minutes or reboot  2) A software upgrdade is in progress. I rebooted the system yesterday and checked on it today via hyperterminal; I still get the same message telling me that the EMC NAS Service did not start. I am not familiar with the commamds to check on and start services in linux. Any help or insight would be much appreciated.
