Changing the Network and System Settings of a Junos Space Virtual Appliance

You can change some basic options that you configured when you first installed and set up your Junos Space Virtual Appliance. You can also change the default system time and retrieve system log files from your Junos Space Virtual Appliance.

Each time you log in from the Junos Space system console, the Junos Space Settings Menu is displayed as follows:

Follow the system prompts from the menu to set or modify menu options. Password changes take effect immediately. Other configuration changes you make do not take effect until you apply the changes.

Note:

An openNMS user does not have permission to modify the Junos Space Settings.

To change a Junos Space Virtual Appliance configuration, you must be a user with administrative privileges and already logged in to the Junos Space Virtual Appliance. You can perform the following tasks from the Junos Space Settings Menu:

Changing the admin User Password of a Junos Space Virtual Appliance

You can change the admin user password used to log in to the Junos Space Network Management Platform.

To change the administrator password:

  1. At the Junos Space Settings Menu prompt, type 1.

    The Change Password menu appears:

  2. Type 1 at the command prompt.

    You are prompted for confirmation.

  3. Type y.

    You are prompted for the current administrator password.

  4. Enter the current administrator password.

    You are prompted to enter the new administrator password.

  5. Enter the new password.

    You can choose a password that is at least eight characters long and contains characters from at least three of the following four character classes: uppercase letters, lowercase letters, numbers (0 through 9), and special characters.

    However, if a password satisfies the preceding criteria but contains only a single uppercase letter at the beginning or only a single number at the end, then that password is considered invalid. For example, Abcdwip9, Qc9rdiwt, and bRfjvin9 are invalid passwords, but AAbcdwip99, Qc9rdiwtQ, and bRfjvin99 are valid passwords.

    Alternatively, instead of using a string of characters, you can choose a passphrase that is between 16 and 40 characters long and contains at least three dictionary words separated by at least one special character. For example, big#three;fork (14 characters long) and circlefaceglass (no special characters) are invalid passphrases, but @big#three;fork& and circle;face;glass are valid passphrases.

    Passwords and passphrases are case-sensitive.

    You are prompted to reenter the new password.

  6. Retype the new password.

    The administrator password is updated and a confirmation message appears followed by the Junos Space Settings Menu.

Changing the Network Settings of a Junos Space Virtual Appliance

Note:

  • From Junos Space Network Management Platform Release 14.1R2 onward, you can configure Junos Space Ethernet interfaces with only IPv4 addresses, or both IPv4 and IPv6 addresses.

  • For a multi-node fabric, we recommend that you modify the network settings by using the Junos Space Network Management Platform GUI.

  • From Junos Space Network Management Platform Release 16.1R1 onward, you can configure access to Junos Space through a Network Address Translation (NAT) gateway.

From the Change Network Settings option of the Junos Space Settings Menu, you can perform the following tasks on a Junos Space Virtual Appliance:

    If you type y, the DNS server is removed and the Junos Space Settings Menu appears:

Modifying the Virtual IP Address

You may need to modify the virtual IP (VIP) address of a Junos Space Virtual Appliance when you move it from one network to another. The virtual appliance reboots after the virtual IP address is modified. For nodes in a Junos Space fabric, you can modify a VIP address from any node in the fabric.

Note:

The VIP address should be in the same subnet as the eth0 interface.

To modify the virtual IP (VIP) address of a Junos Space Virtual Appliance:

    In that case, the following menu appears:

  3. Depending on the menu options displayed, type 4 or 1, to modify the NAT configuration.
    Note:

    The NAT configuration must not be modified in combination with the other changes that require a reboot of the node. If the node is rebooted, the NAT configuration is discarded. In such cases, modify the settings that require a reboot, reboot the node and then modify the NAT configuration.

    The Configuring NAT menu appears:

  4. To configure the IPv4 address:
    Note:

    If you modify only the NAT IPv4 or IPv6 address of a virtual appliance configured to be part of a Junos Space cluster, but yet to be added to the cluster from the Junos Space Platform UI, the last specified IP address overwrites the IP address configured during initial configuration. For example, if the virtual appliance was initially configured with a NAT IPv4 address and while modifying the network settings, you specify an IPv6 address, then the IPv4 address is discarded and the IPv6 address is used for the NAT gateway. If both IPv4 and IPv6 are configured initially, then only the IP address that is modified is updated.

      1. Type 1 and press Enter.

      2. Type the IPv4 address of the NAT outbound SSH interface and press Enter.

        The IP address must be in the range 1.0.0.1 - 223.255.255.254 excluding 127.x.x.x.

Expanding the Drive Size of a Junos Space Virtual Appliance

To increase the virtual machine (VM) drive size on a Junos Space Virtual Appliance, you must first add a disk resource to the VMware Infrastructure client to create a virtual disk. You must then initiate a scan of the new virtual disk. The Expand VM Drive Size option does not expand the drive size If you increase the size of any disk on the Virtual Appliance (for example, using the Edit menu of the vSphere Client). To expand the drive size, you must add disk resources to the host system.

The free space available in all the partitions should be monitored periodically and the available disk space should be increased if required. The /var and /var/log partitions should be monitored more frequently as most of the data are stored in these partitions and the space utilization is high.

Note:

You can expand the VM drive size of a Junos Space Virtual Appliance only when the Junos Space Virtual Appliance is powered on.

To expand the VM drive size of a Junos Space Virtual Appliance:

  1. At the Junos Space Settings Menu prompt, type 6.

    You are prompted to enter the password for the admin user.

    Note:

    If no free space is available on the host for allocation, the No free disk space message appears and the Junos Space Settings Menu is displayed.

  2. Type ter the password for the admin user and press Enter.

    The following caution appears and you are prompted to confirm that you want to continue expanding the VM drive size.

  3. Type y to continue with the procedure or n to return to the Junos Space Settings Menu.

    If you type y, you are prompted to specify the partition that you want to expand.

  4. Type the number present against the partition that you want to expand; for example, type 1 to expand the / partition or 5 to quit expanding disks and return to the Junos Space Settings Menu.

    The free space that can be allocated is displayed and you are prompted to enter the space that you want to allocate to the partition.

  5. Type the additional disk space that you want to allocate and press Enter.

    You can enter the disk space in megabytes (M), gigabytes (G), or terabytes (T). Do not add a space between the number and the unit; for example, 50M and not 50 M, 10G and not 10 G, and so on.

    You are prompted whether you want to expand more drives.

  6. Type y to continue adding disk space or n to return to the Junos Space Settings Menu.

    When you type n, the JBoss and MySQL processes that were stopped are resumed. If the VM drive size was expanded on a primary node, the node becomes secondary when it comes up.
