About This Guide

This guide provides information about how to configure IRIS FailSafe 2.1.x systems with the IRIS FailSafe Samba 2.2 option. The Samba option provides backward and forward capability for all IRIS FailSafe 2.1.x releases.

This option enables Samba resources to be failed over from one node to another if a component fails. This guide is intended as a supplement to the information about configuring IRIS FailSafe that is described in the IRIS FailSafe Version 2 Administrator's Guide.


This guide is written for system administrators who are responsible for configuring and administering an IRIS FailSafe system with the optional IRIS FailSafe Samba software. These system administrators must be familiar with the Samba for IRIX configuration.

This book also assumes that you are familiar with the basic components of IRIS FailSafe described in the IRIS FailSafe Version 2 Administrator's Guide.
