I just tried these steps above and was unable to correct the problem. I even tried to stop all NetApp services, delete the file, and then reboot vCenter to see if it comes up properly. I am running VSC 4.2x3 (beta)
I also am having an issue adding 2 new controllers to the Monitoring and Host Configuration Tab. Getting the error: "The call failed on the server; see server"
In the VSC logs I see this:

Note: 192.168.1.122 is the IP address of some random DHCP device on my network completely unrelated to the NetApp or VMware environment. It is actually an android device. I have no idea where it is getting that from, it has never been used here.
