摘要： A system and method for predicting whether a dynamic reconfiguration of a resource of a resource domain would be successful, prior to attempting the reconfiguration. A resource domain includes one or more computer resources (e.g., physical, logical and pseudo devices) and a graph management agent configured to maintain a graph representing the resources and dependencies between resources. Vertices of the graph represent resources; edges represent dependencies. A resource domain may also include a set of policies or constraints regarding resources and reconfigurations of resources. An illustrative constraint may specify that a particular resource (e.g., a multi-pathed logical device) must have a minimal number of paths (e.g., two). The graph agent identifies the effect the dynamic reconfiguration operation would have upon the resources and dependencies, and determines whether any constraints would be violated. If no constraints would be violated, the graph management agent may indicate that the reconfiguration would succeed.
