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?” on page 26, “How the Package Manager Works”
on page 71, and “Package Configuration Planning” on page 165 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.
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 273).
2. Generate the package configuration file (page 299).
3. Edit the configuration file (page 301).
4. Verify and apply the package configuration (page 308).
5. Add the package to the cluster (page 310).
In configuring your packages, use data from the Package Configuration
Worksheet described under “Package Configuration Planning” on
page 165.
NOTE This is a new process for configuring packages, as of Serviceguard
A.11.18. This manual refers to packages created by this method as
modular packages, and assumes that you will use it to create new
packages; it is simpler and more efficient than the older method,
