Configuring an APC Switch as a Fence
Device
This chapter provides the procedures for configuring an APC switch as a fence device in a Red Hat
cluster using the Conga configuration tool.
Figure 2.1, “Using an APC Switch as a Fence Device” shows the configuration this procedure yields.
In this configuration a three node cluster uses an APC switch as the fencing device. Each node in the
cluster is connected to a port in the APC switch.
