About this Manual...

This document describes how to configure and install highly available SAP systems on HP-UX 11i v2 and HP-UX 11i v3 using Serviceguard. It refers to HP product T2803BA - Serviceguard Extension for SAP (SGeSAP).

To understand this document you have to have knowledge of the basic Serviceguard concepts and commands. Experience in the Basis Components of SAP will also be helpful.

This manual consists of six chapters:

•Chapter 1 "Understanding Serviceguard Extension for SAP" describes how to design a High Availability SAP Environment and points out how SAP components can be clustered.

•Chapter 2 "Planning the Storage Layout" proposes the recommended high available file system and shared storage layout for the SAP landscape and database systems.

•Chapter 3 "Step-by-Step Cluster Conversion" describes the installation of SGeSAP step-by-step down to the HP-UX command level.

•Chapter 4 "SAP Supply Chain Management" specifically deals with the SAP SCM and liveCache technology, gives a Storage Layout proposal and leads through the SGeSAP cluster conversion step-by-step.

•Chapter 5 "SAP Master Data Management" specifically deals with the SAP MDM technology and leads through the SGeSAP cluster conversion step-by-step.

•Chapter 6 "SGeSAP Cluster Administration" covers SGeSAP Administration aspects, as well as the use of different HP-UX platforms in a mixed cluster environment.
