Red Hat ENTERPRISE LINUX 5 - Configuring IPMI Management Boards as Fencing Devices

Configuring IPMI Management Boards
as Fencing Devices
This chapter provides the procedures for configuring IPMI management boards as fencing devices in a
Red Hat cluster using the Conga configuration tool.
Figure 3.1, “Using IPMI Management Boards as Fence Devices” shows the configuration this
procedure yields. In this configuration each node of a three node cluster uses an IPMI 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.
