Yes controller B was powered up but when I do node show it would not show me any information for Node B. also when I log in using service processor I cannot get to system console.

How did you determine that controller B was down? That partner did not notice it implies that Data ONTAP was running at least enough to provide heartbeat. Also you were able to shutdown it - again, it implies it was up. This makes me wonder if the issue is with client access (network, SAN).

Only after I manually power off the controller A then controller B took over. I then brought the Controller A back up and did the give back and the filer worked fine for about 3 hours and same thing happened again. This time I shut down controller A and let it shut down and right now we are operating off of controller B only. Per netapp there is nothing in the logs that I sent them or in autosupport to suggest the root cause. They are asking us to bring controller A again and wait for it to happen again and if it does collect a core dump. This option is not acceptable to us as this affects production. Has anyone seen this before or have any ideas?
Filer failover settings are all correct. We are running CDOT 8.3.1 on FAS8040.
