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 (each
step is described in detail in the sections that follow):
• 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 by creating a monitor package on that
cluster.
• Edit the ContinentalClusters configuration file on a node of your
choice in either 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
Configuring a continental cluster requires root access to all the nodes in
both clusters in the configuration. Before doing the ContinentalClusters
configuration, edit the /.rhosts file on all the nodes of both clusters to
include entries that will allow access by the node on which you will run
the cmapplyconcl command. Here is a sample entry in the /.rhosts file
that allows the root user on system3 to run the cmapplyconcl command
on the node where the /.rhosts file contains the entry:
system3.westcoast.myco.com root
