Symbolic Name


Detailed inventory failed.


This error can occur for the following conditions:

  • The state of the DPM library changes without the changes being communicated to the DPM server. This can happen if tapes are removed, inserted, or moved without running a fast inventory after the operation.

  • The specified tape is in a drive and being backed up.

  • Detailed inventories can raise an error for a failure on each slot. If you have a lot of slots, you might receive too many failure error alerts.

User Action

To resolve this error, do the following:

  • Perform a fast inventory after each tape operation.

  • Ensure that the tape specified for a detailed inventory is not in a drive and being backed up.

  • To reduce the number of detailed inventory failure alerts, create the following registry key. To open the Registry Editor, click Start, click Run, and then type regedit.

    Serious problems can occur if you modify the registry incorrectly. These problems could require you to reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. Always make sure that you back up the registry before you modify it, and that you know how to restore the registry if a problem occurs.

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\1.0\Alert
    Value Name: DetailedInventoryFailed
    Data Type: REG_DWORD
    Value Data 0
    After you have created the registry key, you can check whether detailed inventory jobs fail or succeed by using the Jobs tab in the Monitoring view.
