Managing Serviceguard Extension for SAP Version A.06.00 for Linux, December 2012

Initially no SGeSAP attributes are enabled except for the mandatory attribute
sgesap/sap_global/sap_system, which must be set to the SAP SID designated for the
installation. All others SGeSAP related attributes must be left unspecified at this point.
For a database package, specify the module sgesap/dbinstance. An sgesap/dbinstance
does not have any mandatory attributes.
For a combined package, both sgesap/sapinstance and sgesap/dbinstance module must
be specified. Other combinations are also possible.
NOTE: Specifying the SGeSAP modules automatically adds the necessary Serviceguard modules
such as volume_group or filesystem, or package_ip required for a base package.
SAP base package with Serviceguard modules only
It is possible to create a package configuration only specifying the Serviceguard modules. SGeSAP
modules can be installed later. Such a package configuration requires at least the following
Serviceguard modules:
• volume_group
• filesystem
• package_ip
NOTE:
• Include the service module at this stage to use SGeSAP service monitors (for both SAP instance
and DB) on a later stage.
• Add generic_resource module, if the package is used for a SGeSAP SCS/ERS follow-and-push
configuration.
Creating the package with Serviceguard Manger
NOTE: To create a package you can use either Serviceguard Manager GUI or the CLI. This
section describes GUI steps and the CLI steps are described in the “Creating the package
configuration file with the CLI” (page 57) section.
1. From the Serviceguard Manager Main page, click Configuration in the menu toolbar, and
then select Create a Modular Package from the drop down menu.
2. Click no following the question Do you want to use a toolkit?
3. Click Next >> and in the Package Name window, enter a package name. The Failover package
type is pre-selected and Multi-Node is disabled. The SGeSAP Package with SAP Instances
does not support Multi-Node.
4. Click Next >> and another Create a Modular Package screen appears with the following
messages at the top of the screen:
The recommended modules have been preselected.
Choose additional modules for extra Serviceguard capabilities.
5. The modules in the Required Modules window are set by default and cannot be changed. In
the Select Modules window, you can select additional modules (or clear the default
recommended selections) by selecting the check box next to each module that you want to
add (or remove) from the package.
