Preface

This nineteenth edition of the manual applies to Serviceguard Version A.11.20 for the April 2011

release. Earlier versions are available at http://www.hp.com/go/hpux-serviceguard-docs under

functionality introduced in the Serviceguard A.11.20 April 2011 patches, or their superseding

patches (PHSS_41628 or later). If the Serviceguard A.11.20 April 2011 or one of its superseding

patches has not been installed, some of the information in this manual will not apply, therefore
