All the actions in the template are disabled by default
(commented out). Uncomment the lines corresponding to the desired

The cfengine environment consists of:
Master server (policy host):
local_hostname
Managed clients:
Note that when configuring a master server but not adding any managed clients during the
server configuration, the members entry (list of managed clients), is empty, as shown in the
above example.
A file containing the answers for this run of the Configuration
Synchronization Wizard is stored here...

2.3.1.2 Using the Wizard to Configure a Serviceguard Cluster Synchronization Server
To configure a synchronization server for a Serviceguard cluster, there are two configuration
choices:
• Create a Serviceguard package for the configuration service to ensure high availability.
• Configure a single member of the cluster as if it is a standalone system. The configuration
synchronization service will not be highly available, and this configuration will also not
work properly with the Serviceguard automation features discussed in “Serviceguard
Automation Features” (page 23) and is not recommended.
This section focuses on using the wizard to configure a highly available configuration
synchronization service.
NOTE: Before starting the wizard, all the current cluster members should be up and running
in the cluster. Make sure that this cluster’s MAX_CONFIGURED_PACKAGES value can
accommodate the additional package. For more information on this setting, refer to the Managing
Serviceguard manual that is part of the Serviceguard documentation set.
Start by running the Configuration Synchronization Wizard, csync_wizard(1) by issuing the
following command:
# /opt/dsau/sbin/csync_wizard
Querying the system local_hostname for current status, one moment...
This Configuration Synchronization Wizard (csync_wizard) helps you set
up the Configuration Engine (cfengine) environment. Cfengine is a powerful
tool used to perform policy-based management for groups of systems and
cluster environments.
csync_wizard is a client/server based utility. With csync_wizard, the
user can configure a standalone system or Serviceguard cluster as the
