About the New Features
The subsections that follow discuss the major new capabilities introduced in the A.11.20 release,
as well as those introduced in patches to A.11.20. Information on using these capabilities is in
the latest version of Managing Serviceguard, which you can find at the address given under

Integration of System Fault Management or Custom Defined Monitor in Serviceguard Using Generic
Resources
The feature, generic resources, is a resource monitoring mechanism in Serviceguard that allows
you to monitor critical resources for a package through System Fault Management (SFM), or custom
monitors, by configuring these monitors as user-defined services. It provides integration of custom,
user-defined monitors in Serviceguard by configuring the generic resource parameters as part of
package configuration. For more information, see the latest edition of the Managing Serviceguard
manual. This feature is enabled in the PHSS_42136 patch.
