A matching graphical user interface (GUI) for a storage area network (SAN) management tool is disclosed. The matching GUI allows a user to match a managed object that corresponds to a unit of a SAN with a component of the SAN management tool, so the SAN management tool may validate the configuration of the SAN. The GUI receives information describing a managed object and displays the information and a result of an attempted match of the information with a component. A result indicates a current status of the attempted match. The GUI provides a user-selectable listing of components for the displayed result. The selection of a component from the user-selectable listing of components by a user creates a match between the received information for the unit and the selected component.
