A method to more effectively and efficiently diagnose problems in a storage network is disclosed. In one embodiment, such a method includes generating, for a storage network, a resource map that identifies components therein. For each component in the resource map, the method identifies an importance factor that indicates the component's importance in the storage network. When a problem is detected in the storage network, the method identifies, for each component in the resource map, a potential cause factor that indicates how likely the component is to have caused the problem. The method also calculates, for each component in the resource map, a problem responsibility factor to indicate to what extent the component is held responsible for the problem. A corresponding system and computer program product are also disclosed.
