SYMPTOMS

When you try to perform a fast inventory with the Microsoft System Center Data Protection Manager 2007 (DPM), you receive the following error message:
Type: Fast inventory
Status: Failed
Description: DPM failed to inventory the Tape Library IBM 35XX Tape Library. This is possibly due to a hardware issue. (ID 25011 Details: Internal error code: 0x80990C1B)

End time: MM/DD/YYYYh:mm:ssAM_PM
Start time: MM/DD/YYYYh:mm:ssAM_PM
Library: IBM 35XX Tape Library

CAUSE

This issue occurs when you have tape cleaner media in an IBM 35XX series library, and you use DPM to try to run a fast inventory. When there is tape cleaner media in a slot or drive, and you try to run the fast inventory, this slot or drive returns an unhandled error message. In this scenario, the fast inventory fails.

Note A DPM fast inventory will work as expected when auto cleaning is enabled, and the tape cleaner media is loaded only in special cleaning slots. If the cleaner media is present in a regular slot, the status of the slot is reported as an exception. If the cleaner media is in drive, the status of the drive is also reported as an exception.

Note Similar errors may occur when you try to clean a tape drive by using the DPM GUI, and there is cleaning tape media in the library.

WORKAROUND

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To work around this issue, on the DPM server that contains the tape library, you can add RSMCompatMode as a DWORD Value to the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent
To do this, follow these steps.

Note You must be running Data Protection Manage Service Pack 1 (SP1) or later versions on the server before you follow these steps.

Note The RSMCompatMode registry value is used to specify multiple flags for DPM. The following are the flags that are set by this registry value:
  • 1 = RSM_COMPAT_INIT_ELEMENT_STATUS
  • 4 = RSM_COMPAT_IGNORE_TAPE_INVENTORY_RESULT
  • 8 = RSM_COMPAT_CLEANER_EXCEPTION
