Managing HP Serviceguard for Linux Ninth Edition, April 2009

1. Create a subdirectory for each package you are configuring in the $SGCONF
directory:
mkdir $SGCONF/pkg1
You can use any directory names you like. (See “Understanding the Location of
Serviceguard Files” (page 147) for the name of Serviceguard directories on your
version of Linux.)
2. Generate a package configuration file for each package, for example:
cmmakepkg -p $SGCONF/pkg1/pkg1.conf
You can use any file name you like for the configuration file.
3. Edit each configuration file to specify package name, prioritized list of nodes (with
39 bytes or less in the name), the location of the control script, and failover
parameters for each package. Include the data you recorded on the Package
Configuration Worksheet.
Configuring a Package in Stages
It is a good idea to configure failover packages in stages, as follows:
1. Configure volume groups and mount points only.
2. Distribute the control script to all nodes.
3. Apply the configuration.
4. Run the package and ensure that it can be moved from node to node.
5. Halt the package.
6. Configure package IP addresses and application services in the control script.
7. Distribute the control script to all nodes.
8. Run the package and ensure that applications run as expected and that the package
fails over correctly when services are disrupted.
Editing the Package Configuration File
Edit the file you generated in step 2 of “Using Serviceguard Commands to Configure
a Package ” (page 252). Use the bullet points that follow as a checklist.
• PACKAGE_TYPE. Enter the package type; see “Types of Package: Failover,
Multi-Node, System Multi-Node” (page 190) and “package_type” (page 197).
