The verification is done based on the stable clusters' environment and the proper functioning of
the network communication. In case the network communication between clusters can not be
established or the cluster or package status cannot be determined, manual verification must be
done to ensure that the operation to be performed on the target package will not have a conflict
with other packages configured in the same recovery group.

Verifying the status of Continentalclusters daemons
Use the ps command to verify the status of the Continentalclusters monitor daemons cmclsentryd,
which must be running on the cluster node where the monitor package is running.
For Example:
# ps —ef | grep cmclsentryd
Use the ps command to verify the status of the Continentalclusters daemon cmclapplyd on all
the nodes in Continentalclusters. This daemon is started as part of the Continentalclusters installation
and is required for applying the Continentalclusters configuration.
# ps -ef | grep cmclapplyd
Renaming the Continentalclusters
To rename an existing Continentalclusters:
1. Remove the Continentalclusters configuration.
# cmdeleteconcl
2. Edit the CONTINENTAL_CLUSTER_NAME field in the configuration ASCII file, and run the
cmapplyconcl command to configure the Continentalclusters with a new name.
