Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)
5. Start the rehearsal:
$) cmrecovercl -r -g billing_recgp
NOTE: You can use the cmviewcl command to verify that the rehearsal package
billing_rhpkg was started.
6. Stop rehearsal package:
$) cmhaltpkg billing_rhpkg
7. Restore replication environment for recovery. You must first re-synchronize the recovery disk
from the primary disk and then synchronizing the recovery disk business recovery copy with
the recovery disk.
$) pairresync -g billing _dg
$) export HORCC_MRCF=1
$) pairresync -g billing _dg
$) unset HORCC_MRCF
8. Move the recovery group billing_recgp out of maintenance mode:
$) cmrecovercl -e -g billing_recgp
NOTE: You can use the cmviewconcl command to verify that the recovery group
billing_recgp is not in the maintenance mode.

Maintaining Continentalclusters
The following common maintenance tasks are described in this section:
• Adding a Node to a Cluster or Removing a Node from a Cluster
• Adding a Package to Continentalclusters
• Removing a Rehearsal Package from a Recovery Group
• Modifying a Recovery Group with a new Rehearsal Package
• Removing a Package from the Continentalclusters
• Changing Monitoring Definitions
• Checking the Status of Clusters, Nodes and Packages
• Reviewing Log Files
• Renaming Continentalclusters
• Deleting Continentalclusters configuration
• Checking Java Versions
CAUTION: Never issue the cmrunpkg command for a recovery package when Continentalclusters
is enabled, because there is no guaranteed way of preventing a package that is running on the
one cluster from running on the other cluster if the package is started using this command. The
potential for data corruption is significant.
Adding a Node to a Cluster or Removing a Node from a Cluster
To add a node to or remove a node from Continentalclusters, use the following procedure:
