Shutting Down or Rebooting Nodes in the Junos Space Fabric

From Junos Space Network Management Platform, the Super Administrator can shut down or reboot fabric nodes when they are moved or when their network settings are reconfigured. You shut down or reboot a fabric node from the Fabric page. Optionally, you can enter a message to display to all users who are logged in to the nodes you choose to shut down or reboot. This message is displayed on the users’ CLI consoles and Web browsers.

To shut down or reboot one or more nodes in the fabric:

  1. On the Junos Space Network Management Platform UI, select Administration > Fabric.

    The Fabric page appears.

  2. Select the nodes.
  3. Select Shutdown/Reboot Node(s) from the Actions menu.

    The Shutdown Node dialog box appears.

    Note:

    If the nodes that you selected for shutdown or reboot include hosted virtual machines, then a warning message that the hosted virtual machines will be shut down or rebooted is displayed.

  4. Specify, using the Select action option button, whether you want to shut down or reboot the node:

    • Select Shutdown (which is the default) to shut down the node.

    • Select Reboot to reboot the node.

  5. (Optional) In the Shutdown or reboot in minutes text box, specify the time (in minutes) after which the selected nodes are shut down or rebooted. The default is 1 minute, and the range is 1 through 10 minutes.
  6. (Optional) In the Display message to Console and Browser users text box, enter a message to notify logged-in users about the reboot or shutdown operation so that users can save any changes.

    The message cannot exceed 500 characters and must contain only letters or numbers. Punctuation marks are not allowed.

    To this message, Junos Space Platform appends a message specifying whether this action is a reboot or shutdown operation and the number of minutes after which the nodes are rebooted or shut down.

    Note:

    If you do not enter a message in the Display message to Console and Browser users text box, the users will view the following message The system will be shutdown in X minutes where X is the value you entered in the Shutdown or reboot in minutes text box. If you chose to reboot, users will view The system will be rebooted in X minutes where X is the value you entered in the Shutdown or reboot in minutes text box.

  7. (Optional) In the Reason text box, enter a message to specify the reason for rebooting the node.

    The message cannot exceed 500 characters and can contain letters, numbers, spaces, and special characters. The special characters allowed are hyphen (-), underscore (_), period (.), at symbol (@), dollar ($), caret (^), equal sign (=), square brackets ([]), curly brackets ({}), colon (:), comma (,), and slash (/).

    This message is appended to the audit log entry generated for this task.

  8. Click Confirm to shut down or reboot the node.

    • If you reboot or shut down one node, the node is shut down or rebooted after the configured time interval.

    • If you shut down multiple nodes, the nodes are shut down after the configured time interval.

    • If you reboot multiple nodes, the nodes are rebooted one by one after the configured time interval in the following sequence with an approximate interval of one minute between the reboot operations:

      1. Node acting as a load balancer

      2. Other nodes

      3. Fault Monitoring and Performance Monitoring (FMPM) node

      4. Node that initiated the reboot operations

    Note:

    If you are shutting down a node after a change of IP address, we recommend that you reboot all nodes for the changes to take effect.
