Path activity indicators are used for managing concurrently executing processes which operate a data storage hierarchy. Path activity indicators indicate the activities of paths emanating from a cache which then extend to various portions of the various subsystems. Each path can have a process operating on it for transferring data to any user, a backing store and the cache. Backing store polling is inhibited when a path to any of the devices is active.
