Re-Imaging Commvault HyperScale Appliance

When there are hardware failures in a HyperScale node, the Hyperscale appliance can be re-imaged. An option to preserve the drives (or reinitialize the drives) will be provided during the re-imaging process.

Procedure

  1. Copy the OVA files to an USB drive as follows:
    1. Using a Windows computer, format the device and add a label as follows:
      • Attach the USB drive and allow it to be detected.

        Once the device is detected, an Autoplay dialog box will be displayed.

      • From Windows Explorer, navigate to My Computer.
      • Right-click the USB drive and then click Format.
      • Select xFAT from the File System drop-down list.
      • Under Volume label, type CVLT_OVA.
      • Click Start.

      The USB drive will be formatted.

    2. Once the formatting is completed, create an OVA directory.
    3. Download the following files from the Media Kits area of the Commvault Store.
      • HyperScale Appliance Hosted Engine OVA

        This file will be displayed as HyperScale Appliance <SP_number> Hosted Engine OVA.

        For example, HyperScale Appliance SP9 Hosted Engine OVA.

      • HyperScale Appliance Commserve OVA

        This file will be displayed as HyperScale Appliance <SP_number> Commserve OVA.

        For example, HyperScale Appliance SP9 Commserve OVA.

    4. Rename the files as follows:

      HyperScale_Appliance_<SP_number>_CSOVA.ova to cvhcics.ova

      HyperScale_Appliance_<SP number>_HEOVA.ova.to rhvm-appliance-4.1.20180125.0-1.el7.ova

    5. Copy the files to the OVA directory in the USB drive.
    6. Attach the USB drive to the node.
  2. Create a bootable ISO as follows:
    1. Login to a remote workstation, that has access to the HyperScale nodes.
    2. Download the HyperScale Appliance ISO file from the Media Kits area of the Commvault Store.

      This file will be displayed as HyperScale Appliance <SP_number> ISO.

      For example, HyperScale Appliance SP14 ISO.

    3. Mount the ISO using iRMC as follows.
      1. Open a web browser from a remote workstation and enter the static IP of the iRMC.

        The login screen is displayed.

      2. Type in the credentials for the default administrator account as follows:

        Username: admin

        Password: admin

        Click Login.

        The iRMC Web Server interface is displayed.

    4. Launch the Advanced Video Redirection window as follows:
      1. Click the Advanced Video Redirection (AVR) button displayed on the top-right section of the iRMC Web Server interface, and then click Start Video Redirection.

        This will launch a Java Applet. (If you do not want to use Java Applet, you can use HTML5 viewer. Click Settings > Services > Advanced Video Redirection (AVR) > Favour HTML5 over Java Applet.)

      2. Click the Run button in the Do you want to run this application? prompt.

        The AVR window will be displayed.

      3. Login using the root credentials established during the initial setup.
    5. Mount the media
      1. From the menu, click Media > Virtual Media Wizard.

        The Virtual Media dialog box is displayed.

      2. Click Browse and navigate to the folder containing the downloaded .ISO file.
      3. Select the file and then click Open.
      4. Click Connect.
  3. Restart the node. From the menu, click Power > Power Cycle.
  4. When prompted, choose the Preserve drives option. This will preserve the storage pool disks with the backup data, in the state that it was before re-imaging. (The Reinitialize drives option is used for a fresh installation.)

    The node will boot from the ISO and the imaging will start automatically.

    This process may take some time (approximately 15 minutes) to complete.

    A 'completed successfully' message will be displayed when the imaging process is finished.

  5. Restart the node. (Launch the Advanced Video Redirection window and then click Power > Power Cycle from the menu.
