Upgrading Avaya Enterprise Linux from the software installation DVD

Last Updated : Jun 05, 2026 |

About this task

Use this procedure to upgrade Avaya Enterprise Linux from the Avaya Enterprise Linux software installation DVD. This upgrade method provides both non-interactive as well as automatic upgrade of Avaya Enterprise Linux.

Before you begin

If you plan to use a direct connection to upgrade Avaya Enterprise Linux, ensure that you connect a keyboard and monitor to the server.

If you plan to use a Ethernet connection from a laptop, configure the laptop as described in Preparing to connect to Avaya Enterprise Linux using an Ethernet cable.

Important:

If you have installed a Tomcat application server on the Experience Portal server, the software on the Application server might get deleted during the OS upgrade. Back up the configuration files, data files, Web applications, libraries, and binaries from the directory where the Application server is installed. For more information about the required backup files, contact the application developer.

Procedure

  1. Log in to Linux on the Experience Portal server.

    • If you upgrade through the console:

      • Log in to the local Linux console as a user with root privileges.

    • If you upgrade through a network connection to eth0 or log on remotely:

      • Log in to Linux as a non-root user, for example, cust, and then change to a user with root privileges by entering the su - root command.

    • If you upgrade through a Ethernet connection to eth1:

      • Use a secure shell (SSH) client, such as PuTTY, to open an SSH connection to the IP address 192.11.13.6.

      • If you are an Avaya Services representative, log in to Linux as cust and change to the user root by entering the su - root command.

      • Or log in to Linux as a non-root user, and enter the su - command to change to the root user.

  2. Insert the Avaya Enterprise Linux software installation DVD in to the server's DVD device.
  3. If the DVD device is not automatically mounted, mount the drive by entering the mount /mnt/cdrom command.

    /mnt/cdrom is the mount point associated with the DVD device in the fstab file.

    If you cannot mount the DVD on Avaya Enterprise Linux, see Troubleshooting Avaya Experience Portal to troubleshoot the issue.

  4. Run the bash /mnt/cdrom/Avaya/vpupgrade.sh command to run the Pre-upgrade tool.

    The tool confirms whether you want to upgrade the OS without media.

  5. Type no and press Enter to confirm that you want to upgrade the OS with media.

    The tool prepares the system for the upgrade.

  6. Type y and press Enter to confirm that you want to run the tool.

    The tool confirms whether you want to enable the autoupgrade option.

  7. Type n and press Enter to disable autoupgrade, or type y and press Enter to enable autoupgrade.
    Important:

    If you upgrade through a network connection to eth0, ensure that you enable autoupgrade.

  8. Press Enter to complete the preupgrade tool.
  9. Type Y and press Enter to restart the server.

    If you upgrade through a network connection to eth0, and select the autoupgrade option, the system runs the upgrade procedure after the system restarts. Skip to Step 12 for further instructions.

    If you upgrade through a console, the system displays the Avaya Enterprise Linux installer Welcome screen after the system restarts.

  10. In the Avaya Enterprise Linux installer Welcome screen, type 2 and press Enter at the boot prompt to select the Upgrade option.

    The installer displays the Warning screen.

    Important:

    You must enter your selection on the Welcome screen within 60 seconds. Otherwise, the installer searches for an Ethernet connection on the eth1 interface.

    If the connection is not detected, the installer continues with autoupgrade if you have selected the autoupgrade option. The installer ejects the DVD and reboots if you have not selected the autoupgrade option.

    Note:

    Instead of displaying the Warning screen, the Avaya Enterprise Linux installer might display the No Disks found! /dev/sda missing error. To resolve the issue, type n and press Enter at the Eject CD/DVD before rebooting prompt.

  11. If you upgrade through an Ethernet connection to eth1:
    1. In the command line, enter the ping -t 192.11.13.6 command to determine when the server completes the reboot.
    2. After the server responds to the ping command, type Ctrl-C to stop the ping command.
    3. Open a telnet client, such as PuTTY, and connect to the IP address 192.11.13.6.
      Important:

      You must start the telnet session within 5 minutes of the server responding to ping. If you do not start the telnet session, the installer ejects the DVD and reboots the server.

      Note:

      To use the Windows command telnet as the telnet client:

      • Enter the telnet command.

      • At the Microsoft Telnet> prompt, enter the set term vt100 command.

      • At the Microsoft Telnet> prompt, enter the open 192.11.13.6 command.

      Note: When using telnet connection, the install screen might not display the information clearly.

      The installer displays the Warning screen.

    4. Type u and press Enter at the Specify your choice prompt to select the Upgrade option.

      The installer displays the Warning screen.

  12. On the Warning screen, type yes and press Enter to confirm that you want to upgrade Avaya Enterprise Linux.
    Note:

    If you upgrade remotely, you do not see the Warning screen, and the installer selects the Remote Install/Upgrade option by default.

  13. When the installer completes the upgrade procedure, the server ejects the DVD, and the server reboots automatically.

    If you upgrade remotely, the upgrade procedure is completed when the server ejects the DVD and the server responds to ping from a command line.

  14. Remove the Avaya Enterprise Linux installation DVD from the drive.
  15. When the server reboots, log in to Linux on the Avaya Experience Portal server.
    Note:

    The network login root is disabled after upgrading Avaya Enterprise Linux.

    • If you upgrade through the console, log in to the local Linux console as root.

    • If you upgrade through a regular network connection to eth0, log in to Linux as a non-root user cust and enter the su - command to change to the user root.

    • If you upgrade through an Ethernet connection to eth1, you must perform the following:

      • Use a secure shell (SSH) client, such as PuTTY, to open an SSH connection to the IP address 192.11.13.6.

      • Log in to Linux as a non-root user, cust.

      • Enter the su - command to change to the user root.

    The Enterprise Linux Installer creates craft and sroot accounts but they are disabled with no predefined password. The craft and sroot accounts are Avaya Service Accounts and can only be enabled via EASG control. You should use the cust and root accounts to login to the server. Avaya Enterprise Linux has assigned a default password for both accounts.

    For more details, see State of identity variables in Master Software Image and on first boot.

  16. If the server is an MPP and you have moved the MPP logs to a new directory or partition using the mppMoveLogs.sh script, add the mount point to the /etc/fstab file. For more information, see Administering Avaya Experience Portal on the Avaya Support site.
  17. Configure the Avaya Enterprise Linux time settings.

    For more information, see Verifying server time synchronization.

Next Steps

After you upgrade Avaya Enterprise Linux, upgrade to Avaya Experience Portal 8.1.
