I have a Windows 2003 server running Backup Exec 12.5 with an Exabyte 2, VXA 3 10 tape robotic library. After spending a good deal of time configuring the media and libraries the backup was running fine. When I introduced some new tapes last week and started setting them up the device status has changed to in-use all the time. I cannot run any backup routines any more. I have installed the VXA diagnostic tool and it tests the tape drive out fine. I can load tapes, erase and write through the tool but Backup Exec won't budge. The controller running the tape drive is an Adaptec 2930ALP ultra wide SCSI controller with the latest drivers from Adaptec. Rebooting the server or tape drive doesn't help. I've used the Backup Exec tape drivers provided and not generic ones. The tape drive has the latest firmware and was just serviced recently. I'm at my wits end! Any ideas would be much appreciated!
