New Features for Serviceguard A.11.19
New Kinds of Package Dependency
As of Serviceguard A.11.18, you can make a package dependent on any other package
or packages running on the same cluster node, subject to the restrictions spelled out in
Chapter 6 of Managing Serviceguard.
Serviceguard A.11.19 adds two new capabilities: you can specify broadly where the
package depended on must be running, and you can specify that it must be down.
For more information, see “About Package Dependencies” in Chapter 4 of the latest
version of Managing Serviceguard, and in particular the subsection “Extended
Dependencies”. See also the white paper Serviceguard’s Package Dependency Feature,
which you can find at docs.hp.com under High Availability —>
Serviceguard.

For example, suppose you have a two-node cluster consisting of a large system and a
smaller system. You want all your packages to be able to run on the large system at
