To perform a rolling upgrade

1. Complete the preparatory steps on the first sub-cluster.
2. Log in as superuser and mount the SFHA Veritas Storage Foundation 6.0 installation media.
3. From root, start the installer.

   # ./installer

4. From the menu select G) Upgrade a product; then select 2)Rolling Upgrade;.
5. The installer checks system communications, release compatibility, version information, and lists the cluster name, ID, and cluster nodes. Type y to continue.
6. The installer inventories the running service groups and determines the node or nodes to upgrade in phase 1 of the rolling upgrade. Type y to continue. If you choose to specify the nodes, type n and enter the names of the nodes.
7. The installer performs further prechecks on the nodes in the cluster and may present warnings. You can type y to continue or quit the installer and address the precheck's warnings.
8. Review the EULA, and type y if you agree to its terms.
9. If the upgrade is from the 5.1 SP1 release or later and the boot disk is encapsulated and mirrored, you can create a backup boot disk.

   If you choose to create a backup boot disk, type 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.

   See Re-joining the backup boot disk group into the current disk group.

   See Reverting to the backup boot disk group after an unsuccessful upgrade.

   The installer lists the RPMs to upgrade on the selected node or nodes.

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

    The installer fails over failover service groups to the node or nodes that are not upgraded at this time. The downtime is the time that it normally takes for the service group's failover. The installer stops parallel service groups on the nodes that are to be upgraded.

11. The installer stops relevant processes, uninstalls old kernel RPMs, and installs the new RPMs.

    It performs the configuration for the upgrade and re-starts processes.

    In case of failure in the startup of some of the processes, you may need to reboot the nodes and manually check the cluster's status.

12. Complete the preparatory steps on the nodes that you have not yet upgraded.
13. The installer begins phase 1 of the upgrade on the remaining node or nodes. Type y to continue the rolling upgrade.

    If the installer reboots nodes, restart the installer.

    The installer repeats step 6 through step 11.

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

14. When phase 1 of the rolling upgrade completes, begin phase 2 of the upgrade. Phase 2 of the upgrade includes downtime for the VCS engine (HAD), which does not include application downtime. Type y to continue.

    If the boot disk is encapsulated, you need to reboot nodes when phase 1 completes.

15. The installer determines the remaining RPMs to upgrade. Press Enter to continue.
16. The installer stops Veritas Cluster Server (VCS) processes. Type y to continue.

    The installer performs prechecks, uninstalls old RPMs, and installs the new RPMs. It performs post-installation tasks, and the configuration for the upgrade.

17. Type y or n to help Symantec improve the automated installation.
18. If you have network connection to the Internet, the installer checks for updates.

    If updates are discovered, you can apply them now.

19. To upgrade VCS or Storage Foundation High Availability (SFHA) on the Coordination Point (CP) server systems to version 6.0, upgrade all the application clusters to 6.0. You then upgrade VCS or SFHA on the CP server systems.

    For instructions to upgrade VCS or SFHA on the CP server systems, refer to the appropriate installation guide.
