HyperScale Reference Architecture - Adding Additional Disks for Vertical Scaling

You can add additional disks to the existing MediaAgent nodes to vertically scale the HyperScale Storage Pool block. If you already configured ransomware protection on the MediaAgent node, then the new disks are also secured from ransomware.

Before You Begin

  • Ensure that you have enough disks to equally scale up the MediaAgents nodes of the HyperScale Storage Pool block.

    For example: If you have 3 MediaAgent nodes in your set up and you wish to add disks. In this case, ensure that you add 2 disks per MediaAgent node. Thus, a total of 6 disks would be needed for scaling up vertically.

  • Install the latest Service Pack on the CommServe host.

  • Ensure that the new set of disks are physically added to each MediaAgent node.

    Note

    The same number of disks must be added to all the MediaAgent nodes.

Procedure

  1. Log in to the MediaAgent computer and navigate to the following directory:

    /opt/commvault/Base
    
  2. Run the following command:

    ./CVSDS -d
    

    The command will detect the unused and newly added disks, which is not already a part of the HyperScale Storage Pool block and will display the device information, something similar to the following. All the disks are selected by default.

    Detected unused disk devices which can be initialized to become part of StoragePool. All the existing data on the disk device will be destroyed during initialization. Please select which of the following disk device should be initialized.
    [X] /dev/sdd            50GB
    [X] /dev/sdh            50GB
    
  3. To exclude a disk device from initializing, press <Enter> to uncheck the corresponding check box.

  4. To configure the selected disks for vertical scaleout, press <Enter> on <OK>

  5. Repeat the steps in all the MediaAgent nodes.

Result

The new disk will be added within a few minutes. - up to a maximum of 30 minutes, depending on the Interval (Minutes) between disk space updates parameter. For more information on this parameter, see Media Management Configuration: Service Configuration.
