Preparing Your Systems
Before configuring your cluster, ensure that Serviceguard is installed on
all cluster nodes, and that all nodes have the appropriate security files,
kernel configuration and NTP (network time protocol) configuration.
Installing and Updating Serviceguard
For information about installing and updating Serviceguard, see the
Release Notes for your version at http://docs.hp.com -> High
Availability -> Serviceguard for Linux -> Release Notes.
Understanding the Location of Serviceguard Files
Serviceguard uses a special file, /etc/cmcluster.conf, to define the
locations for configuration and log files within the Linux file system. The
different distributions may use different locations. The following are
example locations for a Red Hat distribution:
############################## cmcluster.conf ###########################
#
# Highly Available Cluster file locations
#
# This file must not be edited
#########################################################################
SGROOT=/usr/local/cmcluster # SG root directory
SGCONF=/usr/local/cmcluster/conf # configuration files
SGSBIN=/usr/local/cmcluster/bin # binaries
SGLBIN=/usr/local/cmcluster/bin # binaries
SGLIB=/usr/local/cmcluster/lib # libraries
SGRUN=/usr/local/cmcluster/run # location of core dumps from daemons
SGAUTOSTART=/usr/local/cmcluster/conf/cmcluster.rc # SG Autostart file
The following are example locations for a SUSE distribution:
############################## cmcluster.conf ###########################
#
# Highly Available Cluster file locations
#
# This file must not be edited
#########################################################################
SGROOT=/opt/cmcluster # SG root directory
SGCONF=/opt/cmcluster/conf # configuration files
SGSBIN=/opt/cmcluster/bin # binaries
SGLBIN=/opt/cmcluster/bin # binaries
SGLIB=/opt/cmcluster/lib # libraries
SGRUN=/opt/cmcluster/run # location of core dumps from daemons
SGAUTOSTART=/opt/cmcluster/conf/cmcluster.rc # SG Autostart file
