8.4. Upgrading the Manager from 4.2 to 4.3

Upgrade the Red Hat Virtualization Manager from 4.2 to 4.3.

Important

If the upgrade fails, the engine-setup command attempts to roll your Red Hat Virtualization Manager installation back to its previous state. For this reason, the previous version’s repositories must not be removed until after the upgrade is complete. If the upgrade fails, detailed instructions display that explain how to restore your installation.

Procedure

  1. Log in to the Manager machine.

  2. Enable the Red Hat Virtualization 4.3 repositories: 

    # subscription-manager repos \
    --enable=rhel-7-server-rhv-4.3-manager-rpms \
    --enable=jb-eap-7.2-for-rhel-7-server-rpms

    All other repositories remain the same across Red Hat Virtualization releases.

  3. Update the setup packages: 

    # yum update ovirt\*setup\* rh\*vm-setup-plugins

  4. Run engine-setup and follow the prompts to upgrade the Red Hat Virtualization Manager: 

    # engine-setup

    When the script completes successfully, the following message appears: 

    Execution of setup completed successfully

  5. Disable the Red Hat Virtualization 4.2 repositories to ensure the system does not use any 4.2 packages: 

    # subscription-manager repos \
    --disable=rhel-7-server-rhv-4.2-manager-rpms \
    --disable=jb-eap-7-for-rhel-7-server-rpms

  6. Update the base operating system: 

    # yum update
    Important

    If any kernel packages were updated, reboot the machine to complete the upgrade.

You can now update the hosts.
