Re-Imaging HyperScale X Nodes

Commvault HyperScale X nodes can be re-imaged when there is no backup data available in the node. For example, after a failed or incorrect installation.

Before You Begin

  • Download the HyperScale Appliance ISO XX from the Commvault Store.

    Note

    x.x is the version number. For example, HyperScale ISO 2.2. Check the Release Date to make sure that it is the most recent version.

  • Copy the ISO to a virtual drive accessible to the node or create an USB Boot Media.

  • Disconnect any cables that are attached to FC HBA's before imaging.

Procedure

  1. Setup the virtual drive or the USB device as the boot media on the server.

    You can do this using either the hardware vendor's remote console interface such as iLO, iRMC, or iDRAC, or using a KVM device, Local Crash Kart, etc. UEFI boot mode is recommended. Disable UEFI secure boot if it is enabled. Refer to the documentation associated with your server for more information.

  2. Restart the node using the ISO media.

    Note

    It may take several minutes for the ISO to boot, and a blank screen may be displayed for some time, approximately up to 5 minutes.

    The main menu will be displayed.

  3. Select the Next button to proceed to the selection menu.

  4. When prompted, choose the Reinitialize drives option.

    The imaging will start automatically and this process may take some time, approximately 45 minutes, to complete.

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

  5. If necessary unmount the ISO from the node.

  6. Restart the node.

  7. After the restart, verify the Commvault File System (CVFS) RPM version using the following command:

  8. Verify the minor version of the RPM using the following command:

    # rpm -qa | grep hedvig

    The resulting output will display the minor RPM version, as shown in the following sample output:

    hedvig-cluster-1.0.0_3564_2484803ffb-1.x86_64
    hedvig-common-1.0.0_3564_2484803ffb-1.x86_64

    In the above example, 3564 is the minor RPM version.

What to Do Next

  • Important: Verify and ensure that all nodes have the same time and timezone settings.

  • Setup the re-imaged node, choosing a deployment method based on your network topology. For more information, see Determining the Network Topology.
