HP Serviceguard for Linux Version A.11.18 Deployment Guide, August 2008

Introduction

Purpose of this Document

The HP Serviceguard for Linux Deployment Guide provides administrators with step-by-step instructions

for ordering, installing and configuring a Serviceguard cluster on two Linux hosts. Using this

deployment guide, administrators can install and configure HP Serviceguard for Linux quickly and

easily. This document pertains to specific hardware and software, but can easily be leveraged for use

in deploying HP Serviceguard for Linux in different environments.

What Has Changed in this Version

The previous version used Device Mapper LUN identifiers of the form /dev/dm-N that were not

persistent, that is, they could change after some failures and reboots. This version describes how to

set up the cluster using /dev/mapper/mpathX format names that are persistent.

Scope

The HP Serviceguard for Linux Deployment Guide:

 Is focused on the steps required to install and configure HP Serviceguard for Linux on a two-

node ProLiant DL cluster running Red Hat Enterprise Linux 5.1 with the HP StorageWorks

2000fc MSA.

 Is intended for customers who are new to clustering and HP Serviceguard. The goal is to

simplify the deployment of a Serviceguard for Linux cluster.

 Describes the minimum hardware and software requirements for Serviceguard for Linux. It

also includes instructions for setting up the hardware, installing the software, and configuring

the cluster with a sample package.

 Assumes that the customer has access to the internet to download the required software.

Although this deployment guide is specific to Serviceguard for Linux Version A.11.18 on HP ProLiant

DL servers (IA32/x86 architecture), the HP StorageWorks 2000fc MSA, and Red Hat Enterprise Linux

5.1, most steps apply to any supported hardware (servers, storage), Linux OS distribution, and

Serviceguard for Linux version. Details of supported configurations can be found in the HP

Serviceguard for Linux Certification Matrix (see the Related Documents section for where to find the

latest version of this matrix).

Audience

This deployment guide is intended for Linux administrators who are new to Serviceguard and for those

who want to use the HP Serviceguard for Linux installation and configuration scripts.
