Hello,

I'm testing ovirt for potential deployment and one of the metrics for its 
success relies on the high availability feature. In my research on this 
feature, I found scattered documentation indicating that fencing is a 
prerequisite. On my test hardware, I don't have any LOM/IPMI but I see that APC 
managed PDUs are supported, which I do have.

The problem is when I try to configure Power Management to use the "apc" type, 
I get this error:

        Test Failed, Host Status is: unknown. The fence-agent script reported 
the following error: 
        Failed: You have to enter plug number Please use '-h' for usage

ovirt-engine/engine.log tells me:

Status is: unknown. The fence-agent script reported the following error:

I've tried to add "port=1" to the Options field but that seems to have no 
effect.

Any ideas? Is there any way to configure a "dumb" power management / fencing 
configuration for testing?

Cheers,
Ian
