Managing HP Serviceguard for Linux Ninth Edition, April 2009

• If you want the package to run an external “pre-script” during startup and
shutdown, use the external_pre_script parameter (see (page 212)) to specify the full
pathname of the script, for example $SGCONF/pkg1/pre_script1.
• If the package will run an external script, use the external_script parameter (see
(page 212)) to specify the full pathname of the script, for example $SGCONF/pkg1/
script1.
See “About External Scripts” (page 137), and the comments in the configuration
file, for more information.
• Configure the Access Control Policy for up to eight specific users or any_user.
The only user role you can configure in the package configuration file is
package_admin for the package in question. Cluster-wide roles are defined in
the cluster configuration file. See “Setting up Access-Control Policies” (page 178)
for more information.
Verifying and Applying the Package Configuration
Serviceguard checks the configuration you enter and reports any errors.
Use a command such as the following to verify the content of the package configuration
file you have created, for example:
cmcheckconf -v -P $SGCONF/pkg1/pkg1.conf
Errors are displayed on the standard output. If necessary, re-edit the file to correct any
errors, then run cmcheckconf again until it completes without errors.
The following items are checked:
• Package name is valid, and at least one node_name entry is included.
• There are no duplicate parameter entries (except as permitted for multiple volume
groups, etc).
• Values for all parameters are within permitted ranges.
• Configured resources are available on cluster nodes.
• File systems and volume groups are valid.
• Services are executable.
• Any package that this package depends on is already be part of the cluster
configuration.
When cmcheckconf has completed without errors, apply the package configuration,
for example:
cmapplyconf -P $SGCONF/pkg1/pkg1.conf
This adds the package configuration information to the binary cluster configuration
file in the $SGCONF directory and distributes it to all the cluster nodes.
