Starting the SSR Processes

Start the SSR process on each node in the cluster, one at a time. Start the SSR process on the nodes in the following order:

  • SM nodes
  • D nodes

After you start the SSR process on the node, check the status of the node and wait for the process to finish starting before moving on to the next node.

  1. Log in to the first SM node.

    Execute:
    root@uranus-js: /opt/JNPRsbr/radius/sbrd start ssr

    Starting ssr management processes
    MySQL Cluster Management Server mysql-5.7.18 ndb-7.5.6
    -Node 51: connected (Version 7.1.8)
    
    Starting ssr auxiliary processes
    root@uranus-js: 
    
  2. After starting the SSR process on the node, monitor the status of the node and make sure that it reconnects to the cluster.

    Execute:
    root@uranus-js: /opt/JNPRsbr/radius ./sbrd status

  3. On the second SM:

    Execute:
    root@sbrha-3: /opt/JNPRsbr/radius/sbrd start ssr

    root@sbrha-3: /opt/JNPRsbr/radius/sbrd status

  4. Start the SSR process on the first D node.
    20:57:47][root@sbrha-9:/opt/JNPRsbr/radius]$ ./sbrd start ssr
    Starting ssr data processes
    You have mail.

  5. After starting the SSR process on the node, monitor the status of the node and make sure that it reconnects to the cluster.

    Execute:
    root@sbrha-9: /opt/JNPRsbr/radius ./sbrd status

  6. On the second D node:

    Execute:
    root@sbrha-7: /opt/JNPRsbr/radius/sbrd start ssr

    root@sbrha-7: /opt/JNPRsbr/radius/sbrd status

  7. After the SSR process has been started on all four nodes, check the status of the cluster from one of the SM nodes.

    Execute:
    root@uranus-js: /opt/JNPRsbr/radius ./sbrd status

    The status of the cluster should look similar to the following example. Notice that all nodes are connected except for (in this example) node IDs 100 and 101. These will be connected after you re-create and restore the cluster database and start the RADIUS processes.

    [07:49:09][root@uranus-js:/opt/JNPRsbr/radius]$ ./sbrd status
