This computer implemented software invention supervises networked system resources with the goal of maximizing service availability, providing on-demand and uninterrupted access to service, and minimizing the down time due to failures. It is a cluster-wide solution that co-ordinates the states and activities of resources, assigns availability roles, implements recovery from failures, and implements overall system policy. To do this, it maintains a system model of the system's physical and logical configuration and models the resources using managed objects that provides an extensive representation of the states, roles, and relationships of the systems resources.
