    Article Summary

    The procedure to upgrade an existing CTERA Portal installation is dependent on whether the upgrade involves upgrading the portal software or both the portal image and the software.

    As a general rule, new releases include both image and software upgrades and CTERA strongly recommends that you upgrade both. The release notes for each release specifies whether a portal image upgrade is required in addition to a portal software upgrade.

    When a performing a portal upgrade that includes upgrading the portal image the image must be upgraded before the software.

    Warning

    When upgradiing from CTERA Portal 7.2.x or earlier, you must upgrade both the portal image to the latest portal image as well as the portal software. After upgrading the portal image, you must reboot every server in the CTERA Portal environment.

    Attempting to upgrade the software from version 7.2.x or earlier without first upgrading the portal image, fails with an error message.

    You can upgrade both the image (Upgrading the Portal Image) and the software via CLI (Upgrading the Portal Software).

    CTERA strongly recommends upgrading the portal image and software with the help of CTERA Support.

    Make sure that the required ports are open, as described in Port Requirements.

    Upgrading the Portal Image

    You have to stop all the portal servers before upgrading the image.

    Note

    Customers without Internet access and upgrading the Portal image from version 6.0.x, require manually installing packages for syslog functionality for offline servers:

    1. Upgrade the portal image with the latest image file, but do not run the setup wizard.
    2. Copy the archive file, exported_images.tar.gz, from the Download Center, to a local folder on the portal machine.
    3. Run the following CLI command on all servers (including main, Replica, DB, and Preview servers): ‘portal-syslog-client load_images images_archive_path‘
      where images_archive_path is the path to the local folder where you copied the archive file.
    4. Run the setup wizard.
      If the setup wizard was run prior to loading the new packages, you must rerun the CLI portal-syslog-client load_images images_archive_path and then restart all servers.
      If you do not run the CLI command, the syslog functionality will not work and an error message is generated. However, if you do not run the CLI command, apart from the error message, there is no impact on portals where syslog functionality is not used.

    To upgrade the CTERA Portal image:

    1. Stop the portal servers.
      First stop all application and preview servers. Next stop the main database server and finally stop the replication database server.
      1. Using SSH, log in as root to each CTERA Portal server.
      2. Run the following command: portal-manage.sh stop
        Once serers are stopped, the Done message is displayed on the screen.
    2. When all servers are in a stop state, upgrade the portal image on each server.
      First upgrade and start the main database server. When this server is up and running upgrade and start an application server and verify that the portal is running without problems. Next upgrade and restart all application and preview servers. Finally, upgrade and restart the replication database server.
      You restart each server using the command portal-manage.sh start
      1. Using SSH, log in as root to the CTERA Portal server.
      2. Copy the upgrade installer to the machine.
      3. Navigate to the location of the installer and run the following command to extract the portal image file: tar xvf portal-installer-linux-x.x.x.tar.bz2 where x.x.x is the version number.
      4. Navigate to the portal-installer-linux-x.x.x subdirectory, where x.x.x is the version number, and run the following command: ./install.sh –u
    Note

    When the release notes specify that the image upgrade also involves a kernel upgrade, an additional restart is also required to complete the kernel upgrade, after restarting each server.

    1. Stop the portal: portal-manage.sh stop
    2. Start the portal: portal-manage.sh start

    Upgrading the Portal Software

    You can upgrade the portal software in the CTERA Portal user interface, or via the command line.

    To upgrade the CTERA Portal software via the portal user interface:

    Warning

    You must contact CTERA Support before using the UI to upgrade the portal software.

    To upgrade the CTERA Portal software via CLI:

    1. Stop the portal servers.
      First stop all application and preview servers. Next stop the main database server and finally stop the replication database server, if available.
      1. Using SSH, log in as root to the CTERA Portal server.
      2. Run the following command: portal-manage.sh stop
        Once services are stopped, the Done message is displayed on the screen.
    2. When all servers are in a stop state, upgrade the primary database portal software.
      1. Using SSH, log in as root to the CTERA Portal server.
      2. Upgrade the portal software: portal-manage.sh upgrade upgrade_file
        where upgrade_file is the software file provided by CTERA.
    3. Restart the primary database server: portal-manage.sh start
    4. After the primary database server is running, using SSH, log in as root to the other CTERA Portal servers.
      1. Upgrade the portal software on each CTERA Portal server: portal-manage.sh upgrade upgrade_file
        where upgrade_file is the software file provided by CTERA.
      2. Restart the CTERA Portal servers.
        First start the replication database server, if available. Next, start the application and preview servers.
        1. Using SSH, log in as root to the CTERA Portal server.
        2. Start the CTERA Portal: portal-manage.sh start
