Hello, I am adding a new to the cluster RAC 11gR2 (6 nodes) on Redhat Linux; ssh connectivity are ok on all nodes and also on the node 7 to be added. When running the addnode.sh from node 1 as a grid user, I have the following errors; -bash-3.2$ ./addNode.sh "CLUSTER_NEW_NODES={db07}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={db07-vip}" Performing pre-checks *for* node addition Checking node reachability...
