The following table shows the status of Continentalclusters packages in a recovery pair when each
cluster is running normally and no recovery has taken place.

Use the following steps to ensure the components are functioning correctly:
1. Make sure all daemons are running.
# ps -ef | grep cmcl
Two important Continentalclusters daemons are cmclsentryd and cmclrmond.
2. Check the cluster configuration on each cluster using the cmviewcl -v command.
a. Ensure that each primary package is running correctly.
b. Ensure that the data sender packages (if any are used for logical data replication) are
running correctly.
c. Ensure that the data receiver packages (if any are used for logical data replication) are
running correctly.
d. Ensure that the Continentalclusters monitor package is running correctly on each monitoring
cluster.
3. On all nodes, use the tail -f /adm/syslog/syslog.log command to check the end
of the SYSLOG file for errors.
4. On nodes where packages are running, check all package log files for errors, including
application packages and the monitor package.
5. Use the following command to verify the correct operation of the Continentalclusters daemon:
# /opt/cmom/tools/bin/cmreadlog -f /var/adm/cmconcl/sentryd.log
6. Make sure the Continentalclusters monitor packages (default name ccmonpkg) on each cluster
fails over properly if a node fails.
