Editing the Configuration File
When you have generated the configuration file that contains the modules your package
needs (see “Generating the Package Configuration File” (page 285)), you need to edit
the file to set the package parameters to the values that will make the package function
as you intend.
IMPORTANT: Do not edit the package configuration file of a Veritas Cluster Volume
Manager (CVM) or Cluster File System (CFS) multi-node or system multi-node package.
Create VxVM-CVM-pkg or SG-CFS-pkg by means of the cmapplyconf command.
Create and modify SG-CFS-DG-id# and SG-CFS-MP-id# using cfs* commands.
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 291).
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 361).
Use the following bullet points as a checklist, referring to the “Package Parameter
Explanations” (page 261), and the comments in the configuration file itself, for detailed
specifications for each parameter.
