Restarting a cluster node

Restarting through the web interface is available only if the application was deployed from an ISO image. If the application was installed from an RPM or DEB package, the restart is performed by using the operating system tools.

A restart of the operating system of a node may be required for applying certain updates, such as OpenSSL library updates. If this is the case, the cluster nodes table displays the Operating system restart is required notification.

To restart the Control node using the application web interface:

1. In the application web interface, select the Nodes section.
2. In the cluster nodes table, select the node with role Control.

   A window containing information about the node opens.

3. Click Restart.
4. In the confirmation window, click Yes.

The operating system will be restarted. This may take some time. Reload the browser page after several minutes. After the restart completes, the login page of the application web interface is displayed.

Traffic processing will be stopped before the restart completes.

To restart the Secondary node using the application web interface:

1. In the application web interface, select the Nodes section.
2. In the cluster nodes table, select the node with role Secondary that you want to restart.

   A window containing information about the node opens.

3. Click the Go to manage node link to go to the web interface of the node with role Secondary.

   The page for connecting to the web interface opens in a new tab of the browser.

4. Enter the account credentials and connect to the node with role Secondary.
5. Click Restart.
6. In the confirmation window, click Yes.

The operating system will be restarted. This may take some time. Reload the browser page after several minutes. After the restart completes, you will see the page for connecting to the web interface of the node with role Secondary.
