6.3. Upgrading to Red Hat Enterprise Virtualization Manager 3.3

The following procedure outlines the process for upgrading Red Hat Enterprise Virtualization Manager 3.2 to Red Hat Enterprise Virtualization Manager 3.3. This procedure assumes that the system on which the Manager is hosted is subscribed to the entitlements for receiving Red Hat Enterprise Virtualization 3.2 packages.
If the upgrade fails, the engine-setup command will attempt to roll your Red Hat Enterprise Virtualization Manager installation back to its previous state. For this reason, the repositories required by Red Hat Enterprise Virtualization 3.2 must not be removed until after the upgrade is complete as outlined below. If the upgrade fails, detailed instructions display that explain how to restore your installation.

Procedure 6.1. Upgrading to Red Hat Enterprise Virtualization Manager 3.3

  1. Subscribe the system to the required entitlements for receiving Red Hat Enterprise Virtualization Manager 3.3 packages.
    Subscription Manager

    Red Hat Enterprise Virtualization 3.3 packages are provided by the rhel-6-server-rhevm-3.3-rpms repository associated with the Red Hat Enterprise Virtualization entitlement. Use the subscription-manager command to enable the repository in your yum configuration. 

    # subscription-manager repos --enable=rhel-6-server-rhevm-3.3-rpms
    Red Hat Network Classic

    The Red Hat Enterprise Virtualization 3.3 packages are provided by the Red Hat Enterprise Virtualization Manager (v.3.3 x86_64) channel. Use the rhn-channel command or the Red Hat Network web interface to subscribe to the Red Hat Enterprise Virtualization Manager (v.3.3 x86_64) channel: 

    # rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3.3

  2. Update the base operating system: 
    # yum update
    In particular, if you are using the JBoss Application Server from JBoss Enterprise Application Platform 6.0.1, you must run the above command to upgrade to Enterprise Application Platform 6.1.
  3. Update the rhevm-setup package to ensure you have the most recent version of engine-setup. 
    # yum update rhevm-setup
  4. Run the engine-setup command and follow the prompts to upgrade Red Hat Enterprise Virtualization Manager. 
    # engine-setup

    Red Hat Network Classic

    Use the rhn-channel command or the Red Hat Network web interface to remove the Red Hat Enterprise Virtualization Manager (v.3.2 x86_64) channels. 

    # rhn-channel --remove --channel=rhel-x86_64-server-6-rhevm-3.2
