Chapter 3. Configuring Red Hat High Availability Add-On With
Conga
This chapter describes how to configure Red Hat High Availability Add-On software using C o n g a.
For information on using Co n g a to manage a running cluster, see Chapter 4, Managing Red Hat High
Availability Add-On With Conga.
Note
Conga is a graphical user interface that you can use to administer the Red Hat High
Availability Add-On. Note, however, that in order to use this interface effectively you need to
have a good and clear understanding of the underlying concepts. Learning about cluster
configuration by exploring the available features in the user interface is not recommended, as
it may result in a system that is not robust enough to keep all services running when
components fail.
