About Modular Packages
Serviceguard A.11.18 allows you to create modular packages, using building blocks
that comprise only the functions that a particular package needs.
IMPORTANT: Serviceguard does not force you to use this new methodology. Existing
packages, known as legacy packages, continue to run without modification, and can
be maintained by means of the older methodology; see “Configuring a Legacy Package”
in Chapter 7 of Managing Serviceguard. You can also still create a new legacy package.
If you are using a Serviceguard Toolkit such as Serviceguard NFS Toolkit, consult the
documentation for that product.
The new modular method of creating packages provides the following benefits:
• All package parameters are now configured in one place, the package configuration
file.
You no longer need to create and distribute a separate package control file.
• External scripts offer an improved means of application integration.
These replace the Customer Defined Functions in the legacy package control script.
You do need to distribute these scripts to all the nodes that can run the package.
• The modular approach allows you to build a package from building blocks
containing only the functions needed by this package.
The subsections that follow provide more information. See also:
• Managing Serviceguard: “Package Configuration Planning” in Chapter 4; and Chapter
6 “Configuring Packages and Their Services”
• The comments in the editable package configuration file output by the cmmakepkg
command, and the cmmakepkg (1m) manpage
