You can stop the autodiscovery process from the Discovery Progress window. (If the Discovery Progress window is not open, select Topology > Show Discovery Progress in the Domain Manager Administration Console to open the window.) In the Discovery Progress window, click Stop Auto Discovery to stop autodiscovery.
Clicking the Stop Auto Discovery button stops the finding of candidate systems for autodiscovery during Phase 3 of the discovery process. However, any systems already in the discovery queue continue to be processed, and the progress of this processing appears in the Discovery Progress window.
Stopping autodiscovery also disables future autodiscovery action until autodiscovery is re-enabled. The IP Manager User Guide provides information on how to re-enable autodiscovery.
