cd WP_PROFILE/ConfigEngine
./ConfigEngine.sh cluster-node-config-vertical-cluster-setup -DServerName=vertical_cluster_server -DWasPassword=foo
- Restart the vertical cluster member referenced in the cluster-node-config-vertical-cluster-setup task.
- In the administrative console for the dmgr, click Save on the task bar, and save administrative configuration.
