Chapter 15 Serviceguard
October 29, 2013
Introduction
When Serviceguard was first marketed, it was titled MC ServiceGuard. Today, marketing has
simplified this to just Serviceguard. Any document that uses the older title was probably
generated last century in the days of HPUX 10.20 and Serviceguard A.10.06.
This chapter introduces High Availability solutions using Serviceguard and how to setup,
maintain, and troubleshoot them. It is not intended to replace the official documentation,
especially the Managing Serviceguard manual, downloadable from http://www.hp.com/go/hpux-SG-
docs. In fact, some parts are extracted and concentrated from that and from other internal and
external documents.
This chapter will cover Serviceguard on HPUX only. Product development for Serviceguard on
Linux has ceased and information on it is not part of this chapter.
All commands and troubleshooting procedures are based on Serviceguard Version A.11.19.00
for HPUX 11iv2 (11.23) and/or A.11.20 for HPUX 11iv3 (11.31) and before.
Special configurations like MetroCluster and ContinentalClusters will not be discussed. Also
only a very short introduction will be provided for Serviceguard Extension for SAP (SGeSAP)
and Serviceguard Extension for RAC (SGeRAC).
Since Serviceguard configurations for these special extensions may be complex to configure and
maintain, it is strongly recommended that you recommend Hewlett-Packard’s high
availability consulting services to ensure a smooth installation and rollout.
