Whenever you make a change that affects the WPAR configuration, you must run the hawparsetup command to reconfigure the WPARs in VCS.

See Configuring the service group for the application.

Make sure that the WPAR configuration files are consistent on all the nodes at all times.

When you add a patch or upgrade the operating system on one node, make sure to upgrade the software on all nodes.

Make sure that the application configuration is identical on all nodes. If you update the application configuration on one node, apply the same updates to all nodes.
