Performing a rolling upgrade of SFCFSHA using the Web-based installer

This section describes using the Veritas Web-based installer to perform a rolling upgrade. The installer detects and upgrades the product that is currently installed on the specified system or systems. If you want to upgrade to a different product, you may need to perform additional steps.

See About rolling upgrades.

To start the rolling upgrade - phase 1

  1. Perform the required steps to save any data that you wish to preserve. For example, take back-ups of configuration files.
  2. Complete updates to the operating system, if required. For instructions, see the operating system documentation.

    The nodes are restarted after the operating system update.

    If you are performing a major OS upgrade (such as Solaris 9 to Solaris 10), do the following:

    • Mount the software disc for the previous version of SFCFSHA.

    • From the top level disc directory, start the installer.

    • Uninstall the SFCFSHA packages.

    • To finish the uninstallation, start the installer again, and install the packages for the previous version of SFCFSHA on the upgraded OS.

      When the installation completes, the CPI prompts you to reboot the nodes again.

    Restart the nodes again manually. Failing to perform this additional reboot prevents the upgrade from proceeding further.

    # shutdown -g0 -y -i6
  3. Start the Web-based installer.

    See Starting the Veritas Web-based installer.

  4. In the Task pull-down menu, select Rolling Upgrade.

    Click the Next button to proceed.

  5. Enter the name of any one system in the cluster on which you want to perform a rolling upgrade.The installer identifies the cluster information of the system and displays the information.

    Click Yes to confirm the cluster information. The installer now displays the nodes in the cluster that will be upgraded during phase 1 of the upgrade.

  6. Review the systems that the installer has chosen for phase 1 of the rolling upgrade. These systems are chosen to minimize downtime during the upgrade.

    Click Yes to proceed.

    The installer validates systems. If it throws an error, address the error and return to the installer.

  7. Review the End User License Agreement (EULA). To continue, select Yes, I agree and click Next.
  8. If you have online failover service groups, the installer prompts you to choose to switch these service groups either manually or automatically. Choose any option and follow the steps to switch all the failover service groups to the other subcluster.
  9. The installer stops all processes. Click Next to proceed.

    The installer removes old software and upgrades the software on the systems that you selected.

  10. If you want to enable volume or file replication or global cluster capabilities, select from the following options:

    • Veritas Volume Replicator

    • Veritas File Replicator

    • Global Cluster Option

    Click Register to register the software. Click the Next button.

    The installer starts all the relevant processes and brings all the service groups online.

  11. When prompted by the installer, reboot the nodes on the first half of the cluster.

    Restart the installer.

  12. Repeat step 6 through step 11 until the kernel packages of all the nodes are upgraded. For clusters with larger number of nodes, this process may get repeated several times. Service groups come down and are brought up to accommodate the upgrade.
  13. Complete updates to the operating system on the nodes that you have not yet upgraded. For instructions, see the operating system documentation.

    The nodes are restarted after the operating system update.

    If you are performing a major OS upgrade (such as Solaris 9 to Solaris 10), do the following:

    • Mount the software disc for the previous version of SFCFSHA.

    • From the top level disc directory, start the installer.

    • Uninstall the SFCFSHA packages.

    • To finish the uninstallation, start the installer again, and install the packages for the previous version of SFCFSHA on the upgraded OS.

      When the installation completes, the CPI prompts you to reboot the nodes again.

    Restart the nodes again manually. Failing to perform this additional reboot prevents the upgrade from proceeding further.

    # shutdown -g0 -y -i6
  14. When prompted, perform step 4 through step 11 on the nodes that you have not yet upgraded.
  15. When prompted, start phase 2. Click Yes to continue with the rolling upgrade.

    You may need to restart the Web-based installer to perform phase 2.

    See Starting the Veritas Web-based installer.

To upgrade the non-kernel components - phase 2

  1. In the Task pull-down menu, make sure that Rolling Upgrade is selected.

    Click the Next button to proceed.

  2. The installer detects the information of cluster and the state of rolling upgrade.

    The installer validates systems. Click Next. If it throws an error, address the error and return to the installer.

  3. Review the End User License Agreement (EULA). To continue, select Yes, I agree and click Next.
  4. The installer stops the HAD and CmdServer processes in phase 2 of the rolling upgrade process. Click Next to proceed.
  5. The installer removes old software and upgrades the software on the systems that you selected. Review the output and click the Next button when prompted. Register the software and click Next to proceed. The installer starts all the relevant processes and brings all the service groups online.
  6. If you have network connection to the Internet, the installer checks for updates.

    If updates are discovered, you can apply them now.

  7. A prompt message appears to ask if the user would like to read the summary file. You can choose y if you want to read the install summary file.

The upgrade is complete.
