Whats the right way to configure fencing when I have redundant power supplies?
You have to be careful when configuring fencing for redundant power supplies. If you configure it wrong, each power supply will be fenced separately and the other power supply will allow the system to continue running. The system won’t be fenced at all. What you really want is to configure it so that both power supplies are shut off and the system is taken completely down. What you want is a set of two fencing devices inside a single fencing method.
