Hi, another related has been puzzling me since I'm new to redhat clustering. I understand that when configuring apc fencing device for each node, I need to fill in the port and switch of the apc device. Port refers to the power outlet which my node is connected to, right? For my case, my node 1 is connected to Outlet 13 of the first pdu. Do I fill in Port=13 or Port=Outlet 13? As for switch, I have absolutely no idea what it refers to. Does it refer to the state I want the outlet to go to during fencing, like 1=Immediate ON, 2=Immediate OFF, 3=Immediate Reboot, etc? Thanks.
