I have a solution containing 2 Power Edge 2950 servers as 2 nodes cluster operating with windows 2003 server and connected to a shared storage MD3000i via SAS connections. This solution was working correctly since 2009. a small period ago we added new Hdd's to the storage since then Node 2 cannot access the storage and the cluster doesn't fail over and the cluster service is up and running on one Node.

Could you please help. And if this solution is not supported and cannot be fixed could any body help by stating  this officially. Or how to get an official statement about this solution to provide to customer.
