HP Serviceguard manual Configuring Packages and Their Services

6 Configuring Packages and Their Services

Serviceguard packages group together applications and the services and resources they depend on.

The typical Serviceguard package is a failover package that starts on one node but can be moved (“failed over”) to another if necessary. See “What is Serviceguard? ” (page 21), “How the Package Manager Works” (page 50), and “Package Configuration Planning ” (page 125) for more information.

You can also create multi-node packages, which run on more than one node at the same time.

System multi-node packages, which run on all the nodes in the cluster, are supported only for applications supplied by HP.

Before you begin, make sure you have done the necessary planning; see “Package Configuration Planning ” (page 125).

Creating or modifying a package requires the following broad steps, each of which is described in the sections that follow:

1.Decide on the package’s major characteristics and choose the modules you need to include ((page 228)).

2.Generate the package configuration file (page 254).

3.Edit the configuration file (page 255).

4.Verify and apply the package configuration (page 259).

5.Add the package to the cluster (page 260).
