cfengine “master”. The master contains the configuration description and configuration files that will be used by all the clients. Clients copy the configuration description from the master and apply it to themselves.
The configuration description supports a rich set of management actions such as copying configuration files from the master to the client, performing edits to files, checking file ownerships, permissions, and checksums, executing shell commands, checking for processes, etc.
For a detailed description of the cfengine management actions, please refer to the cfengine man page.

This system is a member of a Serviceguard cluster. The cfengine configuration will be defined as a package for high availability unless you answer no to the question below. If you answer no, for the purposes of cfengine control, this machine will be treated as a single machine without failover capability for cfengine.
If you accept the default answer of ‘HA’ to the question below, cfengine will be configured as a highly available Serviceguard package. This ensures that your cfengine master server is available as long
as one of the cluster members that can run the package is also available.
You will need a free IP address for this package and you must configure storage for the package before proceeding. For details on creating highly available file systems, please refer to the Managing Serviceguard manual.
Will this master server be Highly Available (HA) [Y]:
The wizard names the package name “csync” for configuration synchronization. This specific package name is required. The LVM storage configuration and network configuration for the package must be set up before continuing or before running the wizard. All the cluster members should also be up and available. For details, refer to the Managing Serviceguard manual, under “Building an HA Cluster Configuration”, “Creating a Storage Infrastructure with LVM.”
