Creating a Disk Library

You can create disk libraries from the CommCell Console or by using the Command Line Interface. For more information on creating disk libraries using command line, see Create a Disk Library Using Command Line.

Before You Begin

Before creating a disk library, make sure to perform the following:


  1. From the CommCell Browser, expand to Storage Resources.

  2. Right-click Libraries, and the click Add | Disk Library.

    The Add Disk Library dialog box appears.

  3. In the Name box, type the name for a disk library.

  4. Select the appropriate MediaAgent from the MediaAgent list.

  5. If the device is a direct-attached library such as SAS/FC/iSCSI for Windows or NFS for UNIX/Linux MediaAgents, define the mount path as a local path.


    If the MediaAgent is a UNIX/Linux MediaAgent, then you must select the Local Path option. To access an Network File System (NFS) share, you must mount the share to your UNIX/Linux MediaAgent. Once the share is mounted, it appears as another local directory on the system. You can provide this directory location in the local path. Configure the NFS mount option local_lock to none. The Commvault software does not support local_lock option set to all, posix or flock, as these settings can cause data inconsistency. If you apply any of these configurations, the mount paths may not come online.

    Do not create mount paths using NFS shares on Windows MediaAgents, as it could cause potential data corruption.

    1. Select Local Path.

    2. In the Disk Device box, enter the mount path location.

  6. If the device is on a network, define the mount path as a network path.


    • The Network Path option is available only for Windows MediaAgents that use CIFs shares.

    • While creating a disk library and defining a network path that uses an SMB or an NFS for file shares, it is recommended that the MediaAgent is in the Local Area Network (LAN). This is because a MediaAgent in Wide Area Network (WAN) leads to increased latencies, thereby resulting in slower read and write performances from the configured mount paths.

    1. Select Network Path.

    2. From the Credential list, select an appropriate credential to access the mount path. To create a new credential, click the Create New button.

      For instructions about adding a credential, see Adding a Credential to Credential Manager.

    3. In the Folder box, enter the mount path location.

  7. Click OK.

    The new disk library appears in the CommCell Browser under Storage Resources | Libraries.
