      The Snapshot Repository field displays the details of the default VDs existing in the system, if there are any.
    • The Name column displays the name of the VD.
    • The Status column displays the status of the VD.
    • The Available Capacity column displays the available capacity on the VD.
    • The Total Capacity displays the total capacity of the VD.
    • If the default VDs do not exist in the system the Snapshot Repository field columns will be blank.
      The status of the VD can be optimal, or degraded, or partially degraded.
  2. In the Select Capacity field, use the drop-down selector to select the appropriate capacity to use for changes to the base virtual drive.
  3. The capacity is dependent on how write-intensive the application is that you are taking snapshots of. The available capacity is the largest free block of capacity on the snapshot repository virtual drive.

    Please refer to the tips provided for allocating capacity in Figure 71.

    If you designate all of the capacity for the Virtual Drive Repository, you cannot use the same virtual drive as a repository for other volumes.

  4. Click Next.
  5. The Enable MegaRAID Recovery wizard- Displaying the selected Virtual Drive appears. This wizard allows you to select the VD to be used as the snapshot repository.
