Upgrade Static Compute Resources

At first upgrade your static compute resources.

  1. Make sure your compute resource is visible and online in the Control Panel.

  2. Download and install the latest OnApp YUM repository file:

    bash#> rpm -Uvh
  3. Upgrade OnApp compute resource installer package:

    yum update onapp-hv-install
  4. Update your server OS components (if required):

    For XEN compute resource:

    bash# /onapp/onapp-hv-install/ -y

    For KVM compute resource:

    bash# /onapp/onapp-hv-install/ -y
  5. Run compute resource installer:
    For XEN compute resource:

    bash# /onapp/onapp-hv-install/ 

    For KVM compute resource:

    bash# /onapp/onapp-hv-install/

    Reboot XEN compute resource, which is running on CentOS 6.x, after upgrade to 4.4.3 XEN version.

  6. Reboot static compute resources.

    For KVM compute resources only: the kernel package update is a part of "Upgrade Static Compute Resources" default procedure. So reboot is required, if kernel package was upgraded and customer is willing Compute Resource(s) running it (for security reason).

    If you do not have the /home/mq/onapp/messaging/credentials.yml file on your compute resources and you plan to deploy an Accelerator, run the following command on the CP server:

    • For all compute resources:

      rake hypervisor:messaging:configure

    • For certain compute resources only:

      rake hypervisor:messaging:configure['']

      To perform the configuration for a number of compute resources, separate their IPs with a space.

      For information on manual configuration for Accelerator, refer to RabbitMQ Configuration for Accelerator.

Upgrade Static Backup Servers

After you upgraded static compute resources, proceed to static backup servers upgrade.

  1. Download the OnApp repository:

    bash#> rpm -Uvh
  2. Update the package:

    yum update onapp-bk-install
  3. Run the following script:

  4. Update your server OS components (if required):

    bash#> /onapp/onapp-bk-install/ -y
