Filter double tapes after hardware fault of tape library

[HansMeiser]

Hello,

recently we had a hardware fault in our tape-library. problem was fixed and tapelibrary is online again. at first connect to veeam all tapes which were stored in the library at this point in time were doubled. the people did a rescan of library etc. and this problem is fixed in veeam GUI, no problem here. I can see 1 tapelibrary and only single tape numbers in stock like expected.

Requesting tapes with VBRTapeMedium looks different. All tapes which are now outside the library in a physical saferoom are doubled in result list. tapes which are located in the library show off only once.
The problem is that i cant differentiate between the doubled tapes. One must be the real tape and the other only a copy. identical is Name, Barcode and even LibraryId. The LibraryId of tapes which are removed from Library is "00000000-0000-0000-0000-000000000000". This is the same id the doubled tapes have. How can i make a difference between the tapes and filter out the double ones like Veeam GUI does? I tried most of Properties of VBRTapeMedium but nothing helps.

Thank you,
Hans
