Chapter 6. Configuring Fencing with Dual Power Supplies

If your system is configured with redundant power supplies for your system, you must be sure to configure fencing so that your nodes fully shut down when they need to be fenced. If you configure each power supply as a separate fence method, each power supply will be fenced separately; the second power supply will allow the system to continue running when the first power supply is fenced and the system will not be fenced at all. To configure a system with dual power supplies, you must configure your fence devices so that both power supplies are shut off and the system is taken completely down. This requires that you configure two fencing devices inside of a single fencing method.
This chapter provides the procedures for using the Conga configuration tool in a Red Hat cluster to configure fencing with dual power supplies.
Figure 6.1, “Fence Devices with Dual Power Supplies” shows the configuration this procedure yields. In this configuration, there are two APC network power switches, each of which runs on its own separate UPS and has its own unique IP address. Each node in the cluster is connected to a port on each APC switch.
