Fast inventory fails when you try to use an IBM 35XX Series mainframe with Data Protection Manager 2007
Article ID: 978901 - View products that this article applies to.
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
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
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.
