Managing the Cluster and Nodes
Chapter 7 317
This halts all nodes that are configured in the cluster.
Automatically Restarting the Cluster
You can configure your cluster to automatically restart after an event,
such as a long-term power failure, which brought down all nodes in the
cluster. This is done by setting AUTOSTART_CMCLD to 1 in the
/etc/rc.config.d/cmcluster file.
