Upgrade Routing Director

The upgrade functionality provided by Paragon Shell enables you to upgrade your Routing Director installation and all the applications running on it to the current release.

You can upgrade to the current Juniper Routing Director Release 2.5.0 from the following releases.

  • Releases 2.4.1 and 2.4.0

  • Release 2.3.0

We do not support upgrading 2.0.0 to any later Juniper Routing Director release. We do not support upgrading directly from releases 2.1.0 and 2.2.0 to release 2.5.0. If you have a release 2.1.0 installation, upgrade to release 2.2.0 first, and 2.4.1 next, and then use the process described in this topic to subsequently upgrade to release 2.5.0. If you have a release 2.2.0 installation, upgrade to release 2.4.1, and then use the process described in this topic to subsequently upgrade to release 2.5.0.

The upgrade process is automated by a set of Paragon Shell commands and carries out the required system checks, retrieves the upgrade package, and executes the upgrade process on the cluster nodes. You can upgrade using a file that is either downloaded locally on your primary node or downloaded directly from a Web page.

During an upgrade, it is important that no change activities including onboarding of devices, provisioning of services or changing other configurations are done in the system. The upgrade will automatically reboot all components and there will be short unavailability during that time. The upgrade process does not affect the traffic through the network and once the upgrade is complete, the devices and services are not reconfigured.

Note:

We recommend that you back up your configuration before upgrading. For information on backing up your current configuration, see Back Up Routing Director Configuration.

Perform the following steps to upgrade to Routing Director Release 2.5.0:

  1. Upgrade Prerequisites—Ensure that all upgrade prerequisites are met

  2. Upgrade the Routing Director cluster—Upgrade the cluster using either Upgrade using the local filename Option or Upgrade using the remote url Option

  3. Upgrade Paragon Shell and the OVA System Files—Upgrade Paragon Shell and the OVA system files on all the cluster nodes

  4. Post Cluster Upgrade Tasks—Perform all the post cluster upgrade tasks to complete the upgrade process.

Upgrade Prerequisites

Before you upgrade the Routing Director cluster, ensure the following.

  • Paragon Shell is accessible and operational.

  • The VM disk size is increased to match the recommended system requirements. Perform the steps described in Increase VM Disk Size.

  • The cluster nodes have the following free disk space available:

    • The primary node from which the cluster was deployed must have 15% of the total disk space + three times the upgrade file size free.

    • The other two primary and worker nodes must have 15% of the total disk space + the same amount as the upgrade file size free.

    • The worker node must have 15% of the total disk space free.

  • Disable and delete previous OpenSearch backup files to free up space.

    1. Disable OpenSearch backup.

    2. Delete the periodic backup job.

    3. Delete all existing OpenSearch backup files.

  • (Optional) Check the current build and OVA version of your existing release from Paragon Shell using the show paragon version command.

Upgrade the Routing Director cluster

Perform the following steps if you want to upgrade Paragon Automaton releases 2.3.0 and 2.4.X to the current 2.5.0 release.

You can upgrade your installation and all the applications running on it using any one of the following two options:

Upgrade using the local filename Option

Use this option for air-gapped environments where your Routing Director installation does not have access to the Internet. However, you need to be able to copy the upgrade_paragon-release-build-id.tgz and upgrade_paragon-release-build-id.tgz.psig files to your primary node.

To upgrade from releases 2.3.0 and 2.4.X to release 2.5.0, perform the following steps.

  1. Log in as root user to the primary node from which the current cluster was installed. You are logged in to Paragon Shell.

  2. Type exit to exit from Paragon Shell to the Linux root shell.

  3. Copy the upgrade_paragon-release-build-id.tgz and upgrade_paragon-release-build-id.tgz.psig files, of the version to which you want to upgrade, to the /root/epic/temp folder.

    You might need to download the upgrade_paragon-release-build-id.tgz and upgrade_paragon-release-build-id.tgz.psig files from the Juniper Software Download site to your local computer before copying it to the primary node.

  4. (Optional) Use the gpg --verify command to validate the digital signature of the upgrade file. For example:

    Here primary1 is the installer primary node. Validation takes a couple of minutes to complete.

  5. Type cli to enter Paragon Shell.

  6. Use the following command to upgrade the Routing Director cluster:

    request paragon cluster upgrade local filename upgrade_paragon-release-build-id.tgz

    For example:

    Here primary1 is the installer primary node. The upgrade command checks the health of the cluster before upgrading. If the cluster health check returns a GREEN status, the cluster is upgraded requiring no further input. If the cluster health check returns a RED status, the cluster is not upgraded. If the cluster health check returns an AMBER status, you are prompted to choose to continue or stop the upgrade.

    Additional upgrade command options:

    You can also use any one or more of the following command options along with the upgrade command while upgrading:

    1. no-confirm—Usage example:

      Use the no-confirm option to ignore the AMBER status and continue with the upgrade without being prompted. However, the no-confirm option does not ignore a RED status.

    2. detach-process—Usage example:

      As the upgrade process takes over an hour to complete, you can let the upgrade run in the background and free up the CLI screen for any other tasks. The command runs the initial health checks and then proceeds with the upgrade. Once the upgrade process starts, the process is detached and moved into the background and you are returned to the command prompt. The upgrade output is logged in the /epic/temp/upgrade.log file. To monitor the status of the upgrade process and print the output onscreen, use the monitor start /epic/temp/upgrade.log command. When the upgrade process completes, a success message similar to the following is displayed on all the cluster nodes:

      If you get disconnected from the VM during the upgrade process, you can periodically check the upgrade log file for status on the upgrade.

    3. input—Usage example:

      Use the input option to pass additional Ansible input parameters to the upgrade command. For example, if you want to enable verbose logging during upgrade, use the -v option.

      request paragon cluster upgrade local filename upgrade_paragon-release-build-id.tgz input "-v"

    Your Routing Director installation and all the applications running on it are upgraded.

    Note that, the upgrade process takes over an hour to complete. If you get disconnected from the VM during the upgrade process, you can periodically check the upgrade log file until you see an output similar to this:

  7. Execute the request paragon health-check command to ensure that the upgraded cluster is healthy and operational.

    The Overall Cluster Status must be GREEN.

  8. Upgrade Paragon Shell and the OVA system files.

    Go to Upgrade Paragon Shell and the OVA System Files.

Upgrade using the remote url Option

Use this option if your Routing Director installation has access to the Internet and the upgrade file is in a remote location.

To upgrade from releases 2.3.0 and 2.4.X to release 2.5.0, perform the following steps.

  1. Log in as root user to the primary node from which your existing cluster was installed. You are logged in to Paragon Shell.

  2. Use the following command to upgrade the Routing Director cluster:

    request paragon cluster upgrade remote url "https://juniper.software.download.site/upgrade_paragon-release-build-id.tgz?query_string"

    For example:

    Here primary1 is the installer primary node. The upgrade command checks the health of the cluster before upgrading. If the cluster health check returns a GREEN status, the cluster is upgraded requiring no further input. If the cluster health check returns a RED status, the cluster is not upgraded. If the cluster health check returns an AMBER status, you are prompted to choose to continue or stop the upgrade.

    Additional upgrade command options:

    You can also use any one or more of the following command options along with the upgrade command while upgrading:

    1. no-confirm—Usage example:

      Use the no-confirm option to ignore the AMBER status and continue with the upgrade without being prompted. However, the no-confirm option does not ignore a RED status.

    2. detach-process—Usage example:

      As the upgrade process takes over an hour to complete, you can let the upgrade run in the background and free up the CLI screen for any other tasks. The command runs the initial health checks and then proceeds with the upgrade. Once the upgrade process starts, the process is detached and moved into the background and you are returned to the command prompt. The upgrade output is logged in the /epic/temp/upgrade.log file. To monitor the status of the upgrade process and print the output onscreen, use the monitor start /epic/temp/upgrade.log command. When the upgrade process completes, a success message similar to the following is displayed on all the cluster nodes:

    3. disk-saving—Usage example:

      Use this option to delete the upgrade_paragon-release-build-id.tgz file as soon as it is unzipped from the primary node. The upgrade command downloads the upgrade file from the remote location and extracts the contents of the file at the beginning of the upgrade process. This option deletes the downloaded file as soon as it is unzipped to free up space on the primary node.

      The advantage of using this option is that you need lesser free space for the upgrade process. The default minimum free space required is 15% of the total disk space + three times the upgrade file size. With this option you need a minimum free space of 15% of the total disk space + two times the upgrade file size.

    4. input—Usage example:

      Use the input option to pass additional Ansible input parameters to the upgrade command. For example, if you want to enable verbose logging during upgrade use the -v option.

      request paragon cluster upgrade remote url "https://juniper.software.download.site/upgrade_paragon-release-build-id.tgz?query_string" input "-v"

    Your Routing Director installation and all the applications running on it are upgraded.

    Note that, the upgrade process takes a little over an hour to complete. If you get disconnected from the VM during the upgrade process, you can periodically check the upgrade log file until you see an output similar to this:

  3. Execute the request paragon health-check command to ensure that the upgraded cluster is healthy and operational.

    The Overall Cluster Status must be GREEN.

  4. Upgrade Paragon Shell and the OVA system files.

    Go to Upgrade Paragon Shell and the OVA System Files.

Upgrade Paragon Shell and the OVA System Files

When your Routing Director installation and all the applications running on it are successfully upgraded, you must upgrade Paragon Shell and the OVA system files.

  1. Exit from the installer primary node Paragon Shell to the Linux root shell by typing exit.

  2. Execute the Paragon Shell upgrade shell script.

    Paragon Shell and the OVA system files are upgraded.

  3. (Optional) Check the build and OVA version of your upgraded cluster from Paragon Shell.

Proceed to perform the post cluster upgrade tasks. See Post Cluster Upgrade Tasks.
