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.
