Manual Configuration
When prompted, enter the name of the client to add
# mkdir -p /var/opt/dsau/cfenginemaster/inputs
Manually Configuring a Standalone Synchronization Server
Start by creating the directory
# /opt/dsau/sbin/cfkey # /var/opt/dsau/cfengine/ppkeys
# cp localhost.pub root-10.0.0.5.pub
# /sbin/init.d/cfservd start
# cfagent --no-lock --verbose --no-splay
# cfrun -- --inform
# cfrun -v -- --verbose
Initial Serviceguard Package Preparation
# mkdir -p /csync/dsau/cfenginemaster/masterfiles
Policyhost = csync.abc.xyz.com
List Managed Clients in cfrun.hosts
Edit the cfservd.conf File
# /opt/dsau/sbin/cfkey
# ccp /etc/rc.config.d/cfservd /etc/rc.config.d/cfservd
# cp localhost.pub root-192.10.25.12.pub
# ccp * /var/opt/dsau/cfengine/ppkeys
# cexec /sbin/init.d/cfservd start
Test the configuration by performing the following steps
# ccp csync csync.conf /etc/cmcluster/csync
Apply the package and start it
# cmapplyconf -P csync.conf # cmmodpkg -e csync

Answer yes y. The wizard then prompts
Where N is the expected number of clients
Answer yes y or press Enter. The next question is
If these choices are correct, continue
Next prompt is
Log files that reside on this cluster can be consolidated
Consolidated package logs would be located here
