Managing HP Serviceguard for Linux Ninth Edition, April 2009

the file to set the package parameters to the values that will make the package function
as you intend.
It is a good idea to configure complex failover packages in stages, as follows:
1. Configure volume groups and mount points only.
2. Check and apply the configuration; see “Verifying and Applying the Package
Configuration” (page 219).
3. Run the package and ensure that it can be moved from node to node.
NOTE: cmcheckconf and cmapplyconf check for missing mount points,
volume groups, etc.
4. Halt the package.
5. Configure package IP addresses and application services.
6. Run the package and ensure that applications run as expected and that the package
fails over correctly when services are disrupted. See “Testing the Package Manager
” (page 271).
Use the following bullet points as a checklist, referring to the “Package Parameter
Explanations” (page 196), and the comments in the configuration file itself, for detailed
specifications for each parameter.
NOTE: Optional parameters are commented out in the configuration file (with a # at
the beginning of the line). In some cases these parameters have default values that will
take effect unless you uncomment the parameter (remove the #) and enter a valid value
different from the default. Read the surrounding comments in the file, and the
explanations in this chapter, to make sure you understand the implications both of
accepting and of changing a given default.
In all cases, be careful to uncomment each parameter you intend to use and assign it
the value you want it to have.
• package_name. Enter a unique name for this package. Note that there are stricter
formal requirements for the name as of A.11.18.
• package_type. Enter failover or multi_node. ( system_multi_node is
reserved for special-purpose packages supplied by HP.) Note
that there are restrictions if another package depends on this package; see “About
Package Dependencies” (page 121).
See “Types of Package: Failover, Multi-Node, System Multi-Node” (page 190) for
more information.
• node_name. Enter the name of each cluster node on which this package can run,
with a separate entry on a separate line for each node.
• auto_run. For failover packages, enter yes to allow Serviceguard to start the package
on the first available node specified by node_name, and to automatically restart it
