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
