Building Disaster Recovery Serviceguard Solutions Using Continentalclusters A.08.00

Recovering the entire cluster after a cluster alert
If a notification defined in a CLUSTER_ALARM statement in the configuration file is not received,
but a CLUSTER_ALERT and the remote site has confirmed the must fail over has been received,
then override the disabled cmrecovercl command by using the -f forcing option.
Use this command only after a confirmation from the primary cluster site.
# cmrecovercl -f
Recovering a single cluster in an N-1 configuration
In a multiple recovery pair configuration where more than one primary cluster is sharing the same
recovery cluster, running cmrecovercl without any option will attempt to recover packages for
all of the recovery groups of the configured primary clusters. Recovery can also be done in this
multiple recovery pair case on a per cluster basis by using option -c.
# cmrecovercl -c <PrimaryClusterName>
