Package can be running.
Changes take effect when applied, whether or not the package is
running. If you add a script, Serviceguard validates it and then (if there
are no errors) runs it when you apply the change. If you delete a script,
Serviceguard stops it when you apply the change.
Add, change, or delete external
scripts and pre-scripts: modular

Both packages can be either running or halted.
Special rules apply to packages in maintenance mode; see “Dependency
Rules for a Package in Maintenance Mode or Partial-Startup Maintenance
Mode ” (page 321).
For dependency purposes, a package being reconfigured is considered
to be UP. This means that if pkgA depends on pkgB, and pkgA is down
and pkgB is being reconfigured, pkgA will run if it becomes eligible to
do so, even if pkgB's reconfiguration is not yet complete.
HP recommends that you separate package dependency changes from
changes that affect resources and services that the newly dependent
package will also depend on; reconfigure the resources and services
first and apply the changes, then configure the package dependency.
For more information see “About Package Dependencies” (page 168).
