DataFrame 440 Cache Status:Corrupt

[mday64]

My DataFrame 440 experienced a hard shutdown due to a prolonged power outage. After rebooting, it will not come online. I can login to it and run diagnostics and reports. Reports show that the NVRAM Card 1 Cache is corrupt. There are two fully redundant 440's in the cluster. I am up and running on SAN02 with virtual manager enabled. I have shut down and removed power to SAN01. I have also installed new cache batteries on both controllers in SAN01. Still no change in Cache Status. Is there a way to clear the cache on the controller? What steps can be taken to repair the issue and bring things back online?
