Hello Serverguy
Pause and unpause the server from the backup exec console.
Make sure your tape drive is using symantec drivers. Open BE console, go to the device tab, right click on your devcie and disable it.
Right on the device and delete it. Browse to X:\Program Files\Symantec\Backup Exex and execute Tapeinst.exe
Above exe will install the latest tape device drivers. Open the BE console and restart all the services
If possible perform a powercycle of your device and the tape drive. Shutdown server and device, 1st switch on device let it get
initialized then switch on the server.
