Building the Continentalclusters
Configuration
If necessary, use the swinstall command to install the
ContinentalClusters product on all nodes in both clusters. Then create
the Continentalclusters configuration using the following steps:
• Prepare the security files.
• Create the monitor package on each cluster containing a recovery
package. Clusters not containing a recovery package may also
monitor the other cluster in the recovery pair by creating a monitor
package on that cluster.
• Edit the ContinentalClusters configuration file on a node of your
choice in any cluster.
• Check and apply the Continentalclusters configuration.
• Start each ContinentalClusters monitor package on it’s cluster.
• Validate the configuration.
• Document the recovery procedure and distribute the documentation
to both sites. Make sure all personnel are familiar with these
procedures.
• Test recovery procedures.
Preparing Security Files
Running a Continentalclusters command requires root access to cluster
information on all the nodes of the participating Serviceguard clusters in
the configuration. Before doing the Continentalclusters configuration,
edit the /etc/cmcluster/cmclnodelist file on each node of all the participating
clusters to include entries that will allow access by all nodes in the
Continentalclusters. Here is a sample entry in the
/etc/cmcluster/cmclnodelist file for a continental cluster configured with
two, two-node Serviceguard clusters:
lanode1.myco.com root
lanode2.myco.com root
nynode1.myco.com root
