Cisco EPN Manager 2.0 MP1 Installation (High Availability Deployment)


Note

In a high availability environment, the point patch and MP1 must be installed on both the primary and secondary servers.

These are the steps for installing Cisco EPN Manager 2.0 MP1 in a deployment configured with high availability:

    Step 1   Download and Install the Point Patch (HA Deployment)
    Step 2   Download and Run the EpnmMP1_​prereq_​sys_​stats Script (HA Deployment)
    Step 3   Download Cisco EPN Manager 2.0 MP1 (HA Deployment)
    Step 4   Install Cisco EPN Manager 2.0 MP1 on Primary and Secondary Servers (HA Deployment)

    Download and Install the Point Patch (HA Deployment)

    Installing PP2 (Cisco EPN Manager 2.0 (0.2.0)) is mandatory for MP1 installation and PP2 includes the contents of PP1 (Cisco EPN Manager 2.0 (0.1.0)) as well. Therefore, if you have not yet installed PP1, you can directly proceed to PP2 installation.

    Follow these steps to install a point patch on top of Cisco EPN Manager 2.0 in a deployment that is already configured for high availability, where the secondary server is registered to a primary server. The point patch must be installed on both the primary and secondary servers.


    Note

    You must start the patch install with the primary server in the Primary Active state and the secondary server in Secondary Syncing state. See the installation steps below for details.

    Patching of primary and secondary HA servers takes approximately one hour. During that period, both servers will be down.

      Step 1   Check the HA status on the primary server:
      1. Log into the primary server as a user with Administrator privileges.
      2. From the left sidebar, choose Administration > Settings > High Availability.
      3. In the HA Status page, confirm that the primary server’s state is Primary Active.
      4. Click HA Configuration and confirm that the Configuration Mode is HA Enabled.
      Step 2   Check the HA status on the secondary server:
      1. Log into the secondary server’s HM web page by entering the following URL in your browser:

        https://serverIP:8082

        Where, serverIP is the IP address or host name of the secondary server.

      2. Enter the authentication key and click Login.
      3. Verify that the Current State Mode is Secondary Syncing.
      Step 3   On the secondary server, download and install the patch:
      1. Login to the secondary server’s HM web page by entering the following URL in your browser:

        https://serverIP:8082

        Where, serverIP is the IP address or host name of the secondary server.

      2. Enter the authentication key and click Login.
      3. Click Software Download at the top right of the Health Monitor window to open the Secondary Server Software Update window.
      4. Enter the authentication key and click Login.
      5. Click the Upload link under the window title, browse to the patch ubf file, and click OK.

        After the successful download or upload of the patch, the patch name will appear under Critical Fixes on the Software Update page, for example, EPN Manager Point Patch.

      6. Install the patch on the secondary server clicking its associated Install button. The secondary server will auto-restart and will not be accessible for a few minutes. After successful installation, the status will change to “Installed”.
      7. On the secondary server, run the ncs status command to ensure all services are up and running. Log into the secondary server's HM page. The status of the secondary server must be Secondary Syncing.
      8. Verify that the patch is listed as "Installed" in the Software Update page of the secondary server.
      Step 4   On the primary server, download and install the patch. Follow Steps 1 to 5 in Download and Install the Point Patch (No HA).
      Step 5   The primary server restarts automatically and the GUI will not be accessible for sometime.
      Step 6   On the primary server, run the following commands in a CLI session:

      1. Run ncs status command to verify if all the services are up and running.

      2. Run ncs ha status command to check the status of the primary server. The status of the primary server must be Primary Active.

      Step 7   Verify that the patch is listed as "Installed" in the Software Update page of the primary server.
      Step 8   Check if the version of the Point Patch is listed correctly in the Login, About and Software Update pages in the Cisco EPN Manager GUI.

      Download and Run the EpnmMP1_prereq_sys_stats Script (HA Deployment)

      IMPORTANT : The following procedure is only required if you are installing Cisco EPN Manager 2.0 MP1 after upgrading from Cisco EPN Manager 1.2 MP7.

      If you are upgrading from Cisco EPN Manager 1.2 MP7, you must run a mandatory script that performs some required configurations to the optimizer. The following procedure explains how to download the script and signature files, validate the script image, and run the script.


      Note
