Just a quick FYI on a new Knowledge Base article for DPM 2007 we recently published.  This article discusses an issue where when you try to perform a fast inventory with Microsoft System Center Data Protection Manager 2007 (DPM), you may 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 can occur 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.


For more details and the documented workaround see the following KB article:
