Conflicts checker is invoked each time a Hardware Node is registered. Thus, when you registering Hardware Node, the check starts to compare the data about Containers hosted on Hardware Node with data stored in Management Node database. For the sake of simplicity, we shall name Container with conflicts as 'conflicted Container'.
In case any conflicts were detected, the status message saying Hardware node was registered, though some conflicts were found appears on the screen. In addition, the Conflicts tab appears within a Hardware Node properties.
To view the list of conflicts detected while registering particular Hardware Node, click on Conflicts tab.
Click on a conflict name in the list, to view details about particular conflict and resolve it. In this case, you are performing manual resolution of conflict.
