Configure the Distributed Storage As a Disk Library

Configure the Distributed Storage as a disk library so that it can be used as a backup target in the CommCell environment.


  1. Create Deduplication Database (DDB) partition and an Index Cache folder on the NVMe disk,on the MediaAgents/proxies as follows. This is recommended for better performance.

    # mkdir /ws
    # mkfs.xfs /dev/<nvme_vol_name>
    # mount /dev/<nvme_vol_name> /ws
    # mkdir –p /ws/ddb/<DDB_partition_name>
    # mkdir -p /ws/IndexCache
    # cd /opt/Commvault/Commvault/MediaAgent
    # ln -s /ws/IndexCache/IndexCache IndexCache
  2. From the navigation pane go to Storage > Disk.

    The Disk page appears.

  3. In the upper-right corner of the page, click Add to add a disk storage.

    The Add disk dialog box appears.

  4. In the Name box, type a name for the storage library, and then click Add.

    The Add storage dialog box appears.

  5. From the MediaAgent list, select the MediaAgent in which the virtual disk is mounted.

  6. In the Backup location box, enter the file path on the MediaAgent where the backup data is stored. This is the mount path location. For example, you can enter /ws/hedvig/CommvaultBackup

    where CommvaultBackup is the name of the vdisk.

  7. If you entered a Distributed Storage location, a Hedvig cluster list appears. From the list, select a Hedvig cluster.

  8. To enable deduplication on the storage, slide the Use deduplication toggle key to the right.

  9. To specify the DDB location on the MediaAgent, enter the DDB path created in the NVMe disk in the Deduplication DB location box.

    You can add additional DDB partitions associated with other MediaAgents/proxies in the configuration. For more information about configuring additional DDB partitions, see Configuring Additional Partitions for a Deduplication Database.

  10. Click Save.

  11. Configure the Index Cache to point to the Index Cache folder on the NVMe disk. For more information on adding the Index Cache folder in the MediaAgent, see Moving the Index Cache Directory.
