Adding Another CommCell

Use the following steps to share the MediaAgent (Library Server) with another CommCell:

  1. Log in to the CommCell where the MediaAgent (Library Server) is located.
  2. From the CommCell Console, navigate to Storage Resources | MediaAgents.
  3. Right-click the MediaAgent and select All Tasks | Configure Library Server.
  4. From the Library Server Configuration dialog box, click OK to add and register a new CommCell.
  5. Enter the CommCell details and access credentials.
  6. Click OK.

    After the MediaAgent verifies that the CommCell is available, a message will appear indicating that the MediaAgent is now shared with the registered CommCell.

  7. Once registered, follow the steps in the Share Library to configure library server from the registered CommCell.

Configuring an Existing Library to Be Shared Across CommCells

If you have a configured library and you want to use the existing library to share across CommCells, perform the following steps:

  1. From the source CommCell, export all media from the configured Library.

    See Export Media Using the Export Media Wizard for instructions.

  2. Note down the Storage Policies that are accessing the existing library.

    Use the following steps to view storage policies.

    1. From the CommCell Browser, navigate to Policies | Storage Resources | Libraries.
    2. Right-click the <Existing Library>, and then click Properties.
    3. Click the Association tab.

      All the Storage Policies and the Storage Policy Copies accessing the library are displayed.

      Note down Storage Policies and Storage Policy copies.

    4. Click OK.
  3. Deconfigure the existing Library.

    Use the following steps to deconfigure:

    1. From the CommCell Console ribbon, click the Storage tab, and then click Expert Storage Configuration.
    2. Select the <Existing MediaAgent> that has the configured library and click Add >> and then click OK.
    3. From the Expert Storage Configuration window, select and right-click the <Library> and then click Deconfigure.
    4. Click Yes on Confirm Deconfigure dialog box.
    5. Click Yes.

    The library is deconfigured in the Expert Storage Configuration window.

  5. Configure the existing library to share across the CommCell.

    See Configure Library for step by step instructions.

    Note: During configuration, in the Add Cell Shared Library dialog box, in the Barcode Range box, specify all the media that were used in the existing CommServe and still be required in that CommServe.

  6. Share the existing library in the target CommCell.

    See Share Library for step by step instructions.

  7. Import media from both CommServe.

    See Import Media for step by step instructions.

    Also, ensure that all media are imported as per the barcode range specified for each CommServe.

  8. In the source CommCell, add data paths for the newly configured Library Server library to the Storage Policies that was noted in step 2.

    Use the following steps to add data path:

    1. From the CommCell Browser, navigate to Policies | Storage Policies | <Storage_Policy>.
    2. Right-click the <Storage Policy Copy> and click Change Data Path.

    4. Click OK.

Modifying the Slot Range

Use the following steps to modify the slot range of the library server. Ensure the slot range is continuous e.g., 11-15.

  1. Log in to the CommCell where you want to update the assigned slots.
  2. From the ribbon in the CommCell Console, click Storage tab.
  3. Click Expert Storage Configuration.
  4. Under Available MediaAgents, select the MediaAgent attached to the library and click Add >>.
  5. Click OK.
  6. Right-click the library and select Properties.
  7. Specify the new Slot Range.

    The slots that are already assigned to other CommCells are visible in the Assigned Slots area.

  8. Click OK.

Configuring the New Slots/Drives in a Shared Tape Library

When a tape library shared across CommCells is upgraded with new slots and/or drives, perform the following steps in Library Server MediaAgent and other MediaAgents that share the library to configure the new slots and drives.

  1. Add the registry key nLSDetectNewSlotsAndDrives in the Additional Settings. Set the value to 1 to enable. See Add or Modify an Additional Setting for step-by-step instructions.
  2. Reset the library to detect and add the new slots and/or drives. See Reset Library for step-by-step instructions.
  3. You can modify the slot range to add the new slots in the library. See Modifying the Slot Range for step-by-step instructions.
  4. If new drives are added, reconfigure the library. See Library and Drive Sharing Across CommCells - Configure Library for step-by-step instructions.
  5. After successful configuration of new drives and slots, remove the registry key nLSDetectNewSlotsAndDrives added in Step 1 from the Additional Settings. See Delete an Additional Setting for step-by-step instructions.

Deconfiguring a Registered CommCell from the Library Server
