Compatibility and Installation Requirements
Read this entire document and any other Release Notes you may have before you begin an
installation.
NOTE: All nodes must be on the same distribution, including errata level and architecture version.
Using different distribution versions within the same cluster is supported only during rolling upgrade.
Servers using processors from Intel and AMD can be mixed in a cluster. For supported rolling
upgrade paths, see Rolling Software Upgrades (page 14). For information about supported
Serviceguard versions, Linux distributions, related software, and hardware, see the documents
listed under “Related Information” (page 22).
Installing HP Serviceguard for Linux
HP provides an automated installation script that takes you through the process of installing and
configuring Serviceguard for Linux, including Serviceguard Manager and ancillary software. For
information and installation instructions, see the latest version of HP Serviceguard for Linux
Deployment Guide, at http://www.hp.com/go/linux-serviceguard-docs.
The cmeasyinstall script automates the installation of Serviceguard and Serviceguard Manager
component rpms that are shipped by HP. This script must be run on each of the node participating
in the cluster. The script checks for the pre-requisite rpms that are required for Serviceguard and
Serviceguard Manager. If they are present, the component rpms are installed. For more information,
see the README_install.txt that is bundled along with the cmeasyinstall script.
Pre-Installation Checklist for Serviceguard
• Before you begin installing Serviceguard, make sure that all components of the cluster have
been upgraded to their latest firmware versions.
• Serviceguard for Linux depends on the xinetd service. Make sure that the xinetd rpm has
been installed from the distribution source (for example, your Linux installation CD) and is
enabled.
To find out if xinetd is running, use a command such as:
ps -ef | grep xinetd
You should see output similar to the following:
root 3954 1 0 Jan17
? 00:00:05 /usr/sbin/xinetd root 15734 15513 0 13:38 pts/1
00:00:00 grep xinetd
If xinetd is not running, check that it is installed as follows:
rpm -qa xinetd
You can use the chkconfig command to enable xinetd if you need to:
/sbin/chkconfig --level 35 xinetd on
• You may need to install additional software from the distribution, depending on which
Serviceguard components you are installing. The following lists all the software you will need
