Managing Serviceguard Extension for SAP Version B.05.10, December 2012

There is one exception in the naming convention, which concerns the dedicated NFS package

sapnfs that might serve more than one SAP SID.

SGeSAP modules are implemented to work independent of the used package naming. For these

packages, the above naming scheme is a recommendation.

For a description and combination restrictions on those packages, refer to chapter “Designing

SGeSAP Cluster Scenarios” (page 8)

The legacy package installation steps cover HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3 using

Serviceguard 11.16 or higher.

Modular packages can be used with HP-UX 11i v2 and HP-UX 11i v3 using Serviceguard 11.18

or higher.

The package creation process is split into the following logical tasks:

• SAP Preparation

• HP-UX Configuration

• Modular Package Configuration

• Legacy Package Configuration

• HA NFS Toolkit Configuration

• Auto FS Configuration

• Database Configuration

• SAP Application Server Configuration

The tasks are presented as a sequence of steps. Each installation step is accompanied by a unique

number of the format XXnnn, where nnn are incrementing values and XX indicates the step

relationship, as follows:

• ISnnn—Installation Steps mandatory for all SAP packages

• OSnnn—Optional Steps

• LSnnn—Installation Steps mandatory for legacy packages only

• MSnnn—Installation Steps mandatory for module based packages only

• ORnnn—Oracle database only steps

• SDnnn—SAPDB/MaxDB or LC database only steps

• DBnnn – DB2 steps only

• SYnnn – Sybase ASE steps only

• REnnn—Replicated Enqueue only steps

If you need assistance during the installation process and need to contact HP support, you can

refer to the installation step numbers to specify your issue. Also include the version of this document.

The installation step numbers were reorganized for this document version and don't resemble

earlier releases.

Whenever appropriate, HP-UX sample commands are given to guide you through the integration

process. It is assumed that hardware as well as the operating system and Serviceguard are already

installed properly on all cluster hosts. Sometimes a condition is specified with the installation step.

Follow the information presented only if the condition is true for your situation.

NOTE: For installation steps in this chapter that require the adjustment of a SAP-specific parameter

to run the SAP system in a switchover environment, example values are given. These values are

for reference ONLY and it is recommended to read and follow the appropriate SAP OSS notes for

SAP's latest recommendation. Whenever possible, the SAP OSS note number is given.
