1. In a clustered environment that processes an application, the clustered environment including a shared disk connected with at least two nodes, a method of failover for a cluster unaware application in the clustered environment in the event of an node failure, the method comprising: identifying a failure of a first node using a cluster manager, wherein the first node provides application resources to a cluster unaware application and wherein a configuration of the first node includes a key registry that identifies each process of the cluster unaware application to the cluster manager; identifying the key registry for each process of the cluster unaware application; activating application resources for the cluster unaware application from the shared disk; protecting the shared disk from corruption during failover; transferring the application resources to a second node; and processing the application from the second node.
