DPM 2016 Table backup drive Disabe/Offline

Question

Hello, world!
I'm working with our Microsoft System Center 2016 Data Protection Manager server and my tape drive (Stand-alone Drive: Hewlett Packard Enterprise LTO Ultrium-8 drive) is unable to write on my protection group, my long-term is working fine to disk, but the long-term, that should be to my tape, is always waiting for tape. The Tape Backup drive is ok on the device manager,
the HP tool can load, format, test writing, and read, but the DPM console never sees the tape as free.

I tried to map with the DPMDriveMappingTool.exe on the DPM management shell, but I get :

Performing Device Inventory ...
No Tape Library Found.Drive Mapping Failed.
Error Code is: 0x80004004, Error Message is: Operation aborted

Any idea?
