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...
/var/opt/dsau/cfengine/tmpdir/csync_wizard_input.txt
This configuration can be reestablished by issuing the following command:
/opt/dsau/sbin/csync_wizard \
-f /var/opt/dsau/cfengine/tmpdir/csync_wizard_input.txt
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 27) 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

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
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.
The csync_wizard helps you set up this system as a cfengine master,
add or remove cfengine-managed clients, and perform the required
security setup.
