HP Serviceguard Generating the Package Configuration File, Before You Start, Cmmakepkg Examples

Generating the Package Configuration File

When you have chosen the configuration modules your package needs (see “Choosing Package Modules” (page 228)), you are ready to generate a package configuration file that contains those modules. This file will consist of a base module (usually failover, multi-node or system multi-node) plus the modules that contain the additional parameters you have decided to include.

Before You Start

Before you start building a package, create a subdirectory for it in the $SGCONF directory (/etc/ cmcluster); for example:

mkdir $SGCONF/pkg1

cmmakepkg Examples

The cmmakepkg command generates a package configuration file. Some examples follow; see the cmmakepkg (1m) manpage for complete information. All the examples create an editable configuration file pkg1.conf in the $SGCONF/pkg1 directory.

NOTE: If you do not include a base module (or default or all) on the cmmakepkg command line, cmmakepkg will ignore the modules you specify and generate a default configuration file containing all the parameters.

For a complex package, or if you are not yet sure which parameters you will need to set, the default may be the best choice; see the first example below.

You can use the-voption with cmmakepkg to control how much information is displayed online or included in the configuration file. Valid values are 0, 1 and 2. -v 0 removes all comments; -v 1 includes a brief heading for each parameter; -v 2 provides a full description of each parameter. The default is level 2.

•To generate a configuration file that contains all the optional modules: cmmakepkg $SGCONF/pkg1/pkg1.conf

•To create a generic failover package (that could be applied with out editing): cmmakepkg -n pkg1 -m sg/failover $SGCONF/pkg1/pkg1.conf

•To generate a configuration file for a failover package that uses relocatable IP addresses and runs an application that requires file systems to be mounted at run time (enter the command all on one line):

cmmakepkg -m sg/failover -m sg/package_ip -m sg/service -m sg/filesystem -m sg/volume_group $SGCONF/pkg1/pkg1.conf

•To generate a configuration file for a multi-node package that monitors cluster resources (enter the command all on one line):

cmmakepkg -m sg/multi_node -m sg/resource $SGCONF/pkg1/pkg1.conf

•To generate a configuration file adding the generic resources module to an existing package (enter the command all on one line):

cmmakepkg -i $SGCONF/pkg1/pkg1.conf -m sg/generic_resource
