Managing Serviceguard Eighteenth Edition, September 2010

5 Building an HA Cluster Configuration
This chapter and the next take you through the configuration tasks required to set up
a Serviceguard cluster. These procedures are carried out on one node, called the
configuration node, and the resulting binary file is distributed by Serviceguard to all
the nodes in the cluster. In the examples in this chapter, the configuration node is named
ftsys9, and the sample target node is called ftsys10. This chapter describes the
following tasks:
• Preparing Your Systems
• Configuring the Cluster (page 242)
• Managing the Running Cluster (page 272)
Configuring packages is described in the next chapter.
