Storage Foundation for Oracle® RAC 8.0.2 Configuration and Upgrade Guide - Linux

To perform a rolling upgrade

1. Log in as superuser and mount the product installation media.
2. Start the installer from the root folder.

   # ./installer

3. From the menu, select Upgrade a Product and from the submenu, select Rolling Upgrade.
4. The installer suggests system names for the upgrade. Press Enter to upgrade the suggested systems, or enter the name of any one system in the cluster on which you want to perform a rolling upgrade and then press Enter.

   The installer checks system communications, release compatibility, version information, and lists the cluster name, ID, and cluster nodes. Press y to continue.

5. The installer lists the running service groups and determines the nodes to upgrade during the rolling upgrade. Press y to continue. If you choose to specify the nodes, press n and enter the names of the nodes.
6. The installer performs further prechecks on the nodes in the cluster and may present warnings. You can press y to continue or quit the installer and address the warnings from the precheck.
7. Review the end-user license agreement, and press y if you agree to its terms.
8. If the boot disk is encapsulated and mirrored, you can create a backup boot disk.

   If you choose to create a backup boot disk, press y. Provide a backup name for the boot disk group or accept the default name. The installer then creates a backup copy of the boot disk group.

9. After the installer detects the online service groups, it prompts you to choose whether to:

   • Manually switch service groups

   • Let the product installer automatically switch service groups

   The downtime is equivalent to the time that it typically takes to fail over a service group.

   Note:

   Veritas recommends that you manually switch the service groups. Automatic switching of service groups does not resolve dependency issues if any dependent resource is not under VCS control.

10. The installer prompts you to stop the applicable processes. Press y to continue.

    The installer evacuates all the service groups to the node or the nodes that are not upgraded at this time.

    It stops the parallel service groups on the nodes that are yet to be upgraded.

11. The installer stops the relevant processes, uninstalls the old kernel RPMs, and installs the new RPMs. It asks if you want to update your licenses to the current version; select Yes or No. Veritas recommends that you update your licenses to fully use the new features in the current release.
12. If the cluster has configured coordination point server-based fencing, the installer may ask you to provide the new HTTPS coordination point server. Provide the value if your are prompted for this input.
13. The installer asks if you want to perform the rolling upgrade. Select Yes to continue.

    The installer performs the upgrade configuration and starts the processes. If the boot disk is encapsulated before the upgrade, the installer prompts you to reboot the node after performing the upgrade configuration.

14. Complete the preparatory steps on the nodes that you have not yet upgraded.
15. On all the nodes, unmount all VxFS file systems that are not under VCS control.

    # umount mount_point

16. If operating system updates are not required, skip this step. Proceed to step 17.

    Otherwise, complete the updates to the operating system on the nodes that you have not yet upgraded. For instructions, see the operating system documentation.

    Repeat steps 1 to 12 for each node.

    When the rolling upgrade is complete on the first subcluster, the rolling upgrade begins on the second subcluster.

17. Offline all cache areas on the remaining node or nodes.

    # sfcache offline cachename

18. The installer begins the rolling upgrade on the remaining nodes. Press y to continue the rolling upgrade. If the installer was invoked on the upgraded (rebooted) nodes, you must invoke the installer again.

    Note:

    In case of an FSS environment, rolling upgrade is performed on one node at a time.

    The installer repeats step 5 through step 15.

    For clusters with a large number of nodes, this process may repeat several times. Service groups are taken down and brought up to accommodate the upgrade.

19. When the rolling upgrade completes, manually mount all the VxFS file systems that are not under VCS control.
20. If you have network connection to the Internet, the installer checks for updates.

    If updates are discovered, you can apply them now.

21. The installer asks you whether you want to read the installation summary file. Press y if you want to read the file.
