3.Halt the package,

#cmhaltpkg <package_name>

4.Validate the package configuration file.

#cmcheckconf -P <output_for_upgraded_package>

5.Apply the package configuration file.

#cmapplyconf -P <output_for_upgraded_package>

6.Run the package on a node in the Serviceguard cluster.

#cmrunpkg -n <node_name> <package_name>

7.Enable global switching for the package.

#cmmodpkg -e <package_name>

Checking the Metrocluster Package Configuration

Starting from HP Serviceguard version A.11.20, the cmcheckconf -vcommand validates the cluster and the package configuration. Starting from the April 2011 patch release, Metrolcuster uses this functionality to ensure the sanity of Metrocluster and the Site Controller package configuration. HP recommends you to set up a cron job to run the cmcheckconf command regularly. For more information about setting the cron job, see Setting up Periodic Cluster Verification section in the latest version of the Managing Serviceguard manual available at http://www.hp.com/ go/hpux-serviceguard-docs —> HP Serviceguard.

“Validating Metrocluster Package” (page 282) lists the checks made on a Metrocluster Package.

When Metrocluster is integrated with

 

 

Site Controller, this check is done only

 

 

when the cmcheckconf [-v]

 

 

command is executed. During

 

 

validation, it creates a list of volume

 

 

groups and diskgroups for all the

 

 

packages controlled by Site Controller

 

 

and does the above check.
