Chapter 5200
Preparing Your Systems
Before configuring your cluster, ensure that all cluster nodes possess the
appropriate security files, kernel configuration, and NTP (network time
protocol) configuration.
Installing and Updating Serviceguard
For information about installing Serviceguard, see the Release Notes for
your version at http://docs.hp.com -> High Availability ->
Serviceguard -> Release Notes.
For information about installing and updating HP-UX, see the HP-UX
Installation and Update Guide for the version you need: go to
http://docs.hp.com and choose the HP-UX version from the list under
Operating Environments, then choose Installing and Updating.
Appendix E, “Software Upgrades,” on page 463 of this manual provides
instructions for upgrading Serviceguard without halting the cluster.
Make sure you read the entire Appendix, and the corresponding section
in the Release Notes, before you begin.
Understanding Where Files Are Located
Serviceguard uses a special file, /etc/cmcluster.conf, to define the
locations for configuration and log files within the HP-UX filesystem.
The following locations are defined in the file:
################## cmcluster.conf ###############
# Highly Available Cluster file locations
# This file must not be edited
#################################################
SGCONF=/etc/cmcluster
SGSBIN=/usr/sbin
SGLBIN=/usr/lbin
SGLIB=/usr/lib
SGRUN=/var/adm/cmcluster
