Occasionally, you may have to bring a cluster up without all the nodes present. Perhaps one of the nodes is being used temporarily for something else or is having a bad hardware day. In any event, it’s possible to bring up the cluster without all nodes. To do that:

cmruncl -n ${node1} -n ${node2}

Ensure that all nodes that are present are listed in the -n ${node} arguments.

NOTE: Ensure that cmcld is not running on any nodes not listed in the -n arguments. Data/cluster corruption will result.
