The Tape library shows in the guest's device manager as an IBM TotalStorage 3573 Tape Library. It has a warning sign, though and Backup Exec shows it Offline.
I am passing through the SCSI device for the library and the LTO5 tape drive into this guest only. There is another SCSI device in the list, however, called "Unknown IBM-ESXS".
Any clues to get the library to be recognized properly in the Windows guest?
