Maintaining a Continental Cluster
The following common maintenance tasks are described in this section:
• Adding a Node to a Cluster or Removing a Node from a Cluster
• Adding a Package to a Continental Cluster
• Removing a Package from the Continental Cluster
• Changing Monitoring Definitions
• Checking the Status of Clusters, Nodes and Packages
• Reviewing Log Files
• Renaming a Continental Cluster
• Deleting a Continental Cluster configuration
• Checking Java Versions
CAUTION Never issue the cmrunpkg command for a recovery package when
ContinentalClusters is enabled, because there is no guaranteed way of
preventing a package that is running on the one cluster from running on
the other cluster if the package is started using this command. The
potential for data corruption is significant.
Adding a Node to a Cluster or Removing a Node from
a Cluster
To add a node to or remove a node from the continental cluster, use the
following procedure:
1. Halt any monitor packages that are running both clusters.
# cmhaltpkg ccmonpkg
2. Add or remove the node in a cluster by editing the Serviceguard
cluster configuration file and applying the configuration.
# cmapplyconf -C cluster.config
