Configuring Basic Settings for a Junos Space Virtual Appliance

After you deploy a Junos Space Virtual Appliance to a VMware ESX server, you must enter basic network and machine information to make your Junos Space Virtual Appliance accessible to the network. You must also increase the virtual appliance drive space.

To configure a deployed Junos Space Virtual Appliance, the VMware Infrastructure client must be connected to the VMware ESX server on which the virtual appliance is running.

This topic includes the following tasks:

Configuring an Appliance that is the First Node in a Cluster or that Will Not Be Added to an Existing Cluster

To configure the settings of a Junos Space appliance that is the first node in a cluster or that will not be added to an existing cluster:

  1. Power on the Junos Space Virtual Appliance:
    1. From the VMware Infrastructure Client, right-click on the Junos Space Virtual Appliance and select Power On from the drop-down menu.
    2. Select the Console tab.

      The VMware Infrastructure Client console screen displays the Junos Space login prompt.

  2. At the Junos Space login prompt, enter admin as your default login name and press Enter.
  3. Enter abc123 as your default password and press Enter.

    Junos Space prompts you to change your default password.

  4. Enter the default password again.
  5. Enter a new password.

    Passwords should include both alpha and numeric characters and be at least 6 characters in length. All passwords are case-sensitive.

  6. Reenter your new password.
  7. Enter a new IP address for interface eth0.

    Note: The first and second appliance or virtual appliance that you configure in a cluster (fabric) must be in the same subnet.

  8. Enter a new subnet mask for interface eth0.
  9. Enter the default gateway as a dotted decimal IP address.
  10. Enter the nameserver address in dotted decimal notation for interface eth0.
  11. Enter Device Management IP interface information:

    If you want to configure a separate interface for device management:

    • Enter y when prompted to configure a separate interface for device management.
    • Enter a new IP address for interface eth3.
    • Enter a new subnet mask for interface eth3.

    If you do not want to configure a separate interface for device management, enter n when prompted.

  12. Enter n when prompted “Will this Junos Space system be added to an existing cluster?”
  13. Enter the IP address for Web access.

    Note: The IP address for Web access must be in the same subnet as the IP address for interface eth0 but must be a different IP address.

  14. Add an NTP server to synchronize the node with an external NTP source. For example, you can specify ntp.juniper.net as the external NTP server.
  15. Enter the display name for this node.

    This is the logical node name that Junos Space displays for the first node in a Junos Space cluster.

  16. Enter a password for the cluster maintenance mode administrator.

    Note: This is the password that a maintenance mode administrator must specify to access maintenance mode and shutdown all Junos Space nodes in the fabric. When in maintenance mode, an administrator can troubleshoot the Junos Space system or perform database restore operations.

  17. Renter the password for cluster maintenance mode.

    The Settings Summary is displayed, as shown in the following example.

  18. Confirm that the information in the Settings Summary is correct:

    • If all summary information is correct, enter A to apply the settings.
    • If any summary information is not correct, enter C to change the settings.

      When you enter C, you will be prompted to reenter all the basic configuration information that you have configured up to this point.

    When you enter A to apply the settings, the Junos Space Settings Menu is displayed, as shown in the following example.
    Junos Space Settings Menu

1> Change Password
2> Set Routing
3> Set DNS Servers
4> Change Time Options
5> Retrieve Logs
6>Expand VM Drive Size
7>Security
8> (Debug) run shell

Q> Quit
R> Redraw Menu

Choice [1-8,QR]:

  19. Enter 6 to Expand VM drive size.

    Junos Space displays the prompt to expand VM (virtual appliance) drive size, as shown in the following example.

    Choice [1-8,QR]: 6

This process will scan this node for additional drive space that you may have added. During this process, performance on this node may be significantly slowed.
Continue? [y/n]
  20. Enter y to start a scan for the 40 GB of additional drive space that you added when you deployed the virtual appliance.
  21. Enter the admin password when prompted.

    Junos Space starts a scan for the 40 GB of additional drive space that you added when you deployed the virtual appliance. When the scan completes, Junos Space displays the results to verify that the file system size was increased to include the new logical volume. The following example shows the results of a scan for additional drive space.

    The Junos Space Settings Menu is displayed.

  22. Enter Q to exit the Junos Space Settings Menu.

    The configuration of the Junos Space Virtual Appliance is now complete.

    Note: To log in to Junos Space from a Web browser, enter “super” as the default user name and “juniper123” as the password.

Configuring an Appliance to Add to an Existing Cluster

To configure the basic settings of a Junos Space appliance that will be added to an existing cluster:

  1. Power on the Junos Space virtual appliance:
    1. From the VMware Infrastructure Client, right-click on the Junos Space Virtual Appliance and select Power On from the drop-down menu.
    2. Select the Console tab and then click inside the console display screen.

      The VMware Infrastructure Client console screen displays the Junos Space login prompt.

  2. At the Junos Space login prompt, enter admin as your default login name and press Enter.
  3. Enter abc123 as your default password and press Enter.

    Junos Space prompts you to change your default password.

  4. Enter the default password again.
  5. Enter a new password.

    All passwords are case-sensitive.

    3. Specify an NTP server, using the same external NTP source that you configured for the first node in the cluster.

      Note: Juniper strongly recommends that you configure an external NTP source for each node in the cluster, and that each node in the cluster (fabric) is configured with the same NTP server that is configured on the first node.

    4. Enter A to apply the settings and add the NTP server.
  18. Enter Q to exit the Junos Space Settings Menu.

    The basic configuration of the Junos Space Virtual Appliance is now complete.

For each appliance that you add to an existing fabric, you must add the node in the Junos Space user interface, as described in Managing Nodes in the Fabric.
