Stopping and starting nodes on MC
You can start and stop one or more database nodes through the Manage page by clicking a specific node to select it and then clicking the Start or Stop button in the Node List.
Note
The Stop and Start buttons in the toolbar start and stop the database, not individual nodes.On the Databases and Clusters page, you must click a database first to select it. To stop or start a node on that database, click the View button. You'll be directed to the Overview page. Click Manage in the applet panel at the bottom of the page and you'll be directed to the database node view.
The Start and Stop database buttons are always active, but the node Start and Stop buttons are active only when one or more nodes of the same status are selected; for example, all nodes are UP or DOWN.
After you click a Start or Stop button, Management Console updates the status and message icons for the nodes or databases you are starting or stopping.
