Physical Data Replication for ContinentalClusters Using EMC SRDF
Setting up the Continental Cluster Configuration
Chapter 7346
# cmapplyconf -P /etc/cmcluster/ccmonpkg/ccmonpkg.config
7. Restore the logical SRDF links for the package. See the script
Samples-CC/post.cmapply for an example of how to automate this
task. The script must be customized with the appropriate
Symmetrix device group names. Example:
# Samples-CC/post.cmapply
8. Generate the cluster configuration file using cmapplyconcl. Files are
placed in /etc/cmconcl/instances. There is no change to
/etc/cmcluster/cmclconfig nor is there an equivalent file for
ContinentalClusters. Example:
# cmapplyconcl -C cmconcl.config
NOTE You must create/edit /.rhosts on all the systems in the continental
cluster to allow write access to the system running the cmapplyconcl.
After the ContinentalClusters configuration file is successfully
generated the file or system entries can be deleted.
9. Start the monitor package on both clusters.
NOTE The monitor package for a cluster checks the status of the other
cluster and issues alerts and alarms, as defined in the
ContinentalClusters configuration file, based on the other cluster’s
status.
10. Check /var/adm/syslog/syslog.log for messages. Also check the
ccmonpkg package log file.
11. Start the primary packages on the primary cluster using cmrunpkg.
Test local failover within the primary cluster.
12. View the status of the ContinentalCluster primary and recovery
clusters, including configured event data:
# cmviewconcl -v
The continental cluster is now ready for testing. See “Testing the
Continental Cluster” on page 245.
