Chapter 5. Configuring HP ILO Management Boards as Fencing Devices
This chapter provides the procedures for configuring HP iLO management boards as fencing devices in a Red Hat cluster using the Conga configuration tool.
Figure 5.1, “Using HP iLO Management Boards as Fence Devices” shows the configuration this procedure yields. In this configuration each node of a three node cluster uses an HP iLO management board as its fencing device.
Note
Note that in this configuration each system has redundant power and is hooked into two independent power sources. This ensures that the management board would still function as needed in a cluster even if you lose power from one of the sources.

Table 5.1, “Configuration Prerequisities” summarizes the prequisite components that have been set up before this procedure begins.
