Managing Systems and Workgroups: A Guide for HP-UX System Administrators

Configuring a System
Using Distributed Systems Administration Utilities
Chapter 3150
If a standalone system is the master server, by default the master
copy of update.conf is located in
/var/opt/dsau/cfengine_master/inputs/. The master copies of
other configuration files such as cfagent.conf, cfservd.conf, and
cfrun.hosts are also located here. If the master server is a
Serviceguard cluster, the master configuration files are located in the
mount point associated with the package. For example, if this mount
point is named csync, the path would be
/csync/dsau/cfengine_master/inputs.
5. When copying the configuration files to the local system, cfagent
places them in /var/opt/dsau/cfengine/inputs for both
standalone systems and clusters. cfagent first evaluates the
contents of update.conf in order to update any changed cfengine
binaries (if any) and gets the latest version of the policy files
(cfagent.conf and related files.
cfagent then evaluates cfagent.conf to determine the client is in
the desired state. If there are deltas, cfagent performs the defined
actions to correct the clients configuration.
cfengine Master Server Deployment Models
The cfengine master server can be a standalone HP-UX system
servicing groups of distributed clients. The clients can themselves be
standalone systems or members of a Serviceguard cluster. If you are
already using a Systems Insight Manager central management server,
this can be an ideal system to use as a cfengine master server. Master
servers can also act as clients and the configuration synchronization
tasks can be performed on these systems as well as the remote clients.
If you are managing Serviceguard clusters, cfengine can be deployed
strictly for intra-cluster use to synchronize the members of a single
cluster. In this configuration, cfservd is configured as a package for high
availability but the only cfengine clients are the cluster members
themselves. The package’s DNS name/IP address is the name for the
cfengine master server.
In addition to providing configuration synchronization as an
intra-cluster service, another Serviceguard configuration has the cluster
providing the highly available configuration synchronization service to
groups of remote client systems. Those clients can be standalone systems
or Serviceguard clusters. The cluster providing the cfengine service can
be a client of itself and also take advantage of cfengine’s configuration
synchronization features.
