Attach a physical tape drive (SAS) to Hyper-V 2012 Virtual Machine

I will have Backup Exec 2012 running on a Windows 2008 R2 virtual machine which is hosted on a Windows 2012 R2 Hyper-V server and want to know if it is possible to connect a physical LTO5 tape drive / library to the Hyper-V server and make it available to the Backup Exec VM.

I have previously been advised that it is possible by a Symantec engineer but since read that this is not the case, or if it is, it isn't supported.  Does anyone know how I can do this or get around the problem?  If there are any 3rd party products which can help, then that could also possibly be an option (depending on security accreditation).

Thanks.
