A system for updating management entities or devices in a computer system network with configuration change information from the devices being managed. The management entities are configured to discover, monitor and configure managed devices, such as storage systems, connected to the network. Preferably, the managed devices include a comparator which can track changes made to the managed device configuration or properties and report that change back to the various management entities. In this way, the management entities can keep track of the configurations of the various devices that they manage, even though they might not be responsible for issuing the configuration change. This can be accomplished even when managed devices developed by different manufacturers according to different standards or protocols are involved.
