I find it easier to navigate using something like Notepad++ so I can collapse elements. When doing that, you can see the different root level XML nodes, you'll want to look for the controller ones...
Expand each one and verifiy the information...you want to make sure they're valid.
There will be three different kinds of "controller" objects, each one will have slightly different fields populated.
- The cluster(s)
- The node(s)
- The SVM(s)
The values in the XML file should match what's being show in the interface. If you have controllers which are no longer reachable and can't be removed (like I did), you can remove them directly from the XML file.
