Removing a Package from the Continental Cluster
To remove a package from the ContinentalClusters configuration, you
must first remove the recovery group from the ContinentalClusters
configuration file.
Removing the package does not require you to bring down either cluster.
However, in order to implement the new configuration, you must
1. Edit the continental clusters configuration file, deleting the recovery
group.
2. Halt the monitor packages on both clusters.
3. Use the cmapplyconcl command to apply the new
ContinentalClusters configuration.
4. Restart the monitor packages on both clusters.
5. Use the ServiceGuard cmdeleteconf command to remove each
package in the recovery group.
6. View the status of the continental cluster.

Changing Monitoring Definitions
You can change the monitoring definitions in the configuration without
bringing down either cluster. This includes adding, removing, or
changing the cluster events; changing the timings; and adding,
removing, or changing the notification messages.
Use the following steps:
1. Edit the continental clusters configuration file to incorporate the new
or changed monitoring definitions.
2. Halt the monitor packages on both clusters.
