I just enabled power management/fencing successfully on two of my hosts (Dell poweredge R720s with Idrac 7) but am failing to add the third. I enter the IP and user/pass like the others, it takes 15 seconds or so they spits out "Test Failed: Internal JSON-RPC error"

I tried resetting the IDRAC on that server. I can also ping it and access it fine in a web browser. I can ping it from the host as well.

Is there any configuration in IDRAC that could be blocking the fence attempt or any logs in oVirt I can look at to figure out what might be happening with the connection?

I see there is a "fence_idrac" command on the hosts but unsure what switches to use with it to test.

Thanks!
