Managing Serviceguard 14th Edition, June 2007

Building an HA Cluster Configuration
Managing the Running Cluster
Chapter 5 267
To enable automatic cluster start, set the flag AUTOSTART_CMCLD to 1 in
the /etc/rc.config.d/cmcluster file on each node in the cluster; the
nodes will then join the cluster at boot time.
Here is an example of the /etc/rc.config.d/cmcluster file:
#************************ CMCLUSTER ************************
# Highly Available Cluster configuration
#
# @(#) $Revision: 72.2 $
#
# AUTOSTART_CMCLD: If set to 1, the node will attempt to
# join it's CM cluster automatically when
# the system boots.
# If set to 0, the node will not attempt
# to join it's CM cluster.
#
AUTOSTART_CMCLD=1
NOTE The /sbin/init.d/cmcluster file may call files that Serviceguard
stored in the directories: /etc/cmcluster/rc (HP-UX) and
${SGCONF}/rc (Linux). The directory is for Serviceguard use only! Do not
move, delete, modify, or add files to this directory.
Changing the System Message
You may find it useful to modify the system's login message to include a
statement such as the following:
This system is a node in a high availability cluster.
Halting this system may cause applications and services to
start up on another node in the cluster.
You might wish to include a list of all cluster nodes in this message,
together with additional cluster-specific information.
The /etc/issue and /etc/motd files may be customized to include
cluster-related information.
