First, ensure that you have installed 'Enable Robotic Library' option while installing Backup Exec. To confirm, start setup program of Backup Exec and reinstall this component.
After confirming the above, please refer to the following guidelines to resolve this issue.
Reconfigure the tape device using following steps.
1. From Backup Exec | Devices Right Click the device/library | Properties | Uncheck "Enable device for backup Exec" Right click and delete the device.
2. From :\Program Files\VERITAS\Backup Exec\NT
3. Run tapeinst.exe
4. Install Veritas tape drivers.
Uninstall the existing device drivers and reinstall the latest Veritas drivers. Run tapeinst.exe to install Veritas driver.
"TAPEINST.EXE" is located in the directory x:\Program Files\VERITAS\Backup Exec\NT (TAPEINST.EXE" is an automated installation application for installing tape device drivers )

*Check that you are using the updated SCSI controller card firmware and the updated device firmware.
*The target IDs for an auto-loader and tape drive that are Multi-ID Based should be configured with the target ID for the changer (robotic arm) lower than the target ID for the tape drive, avoiding 0 or 1 as these are generally reserved for boot devices ( i.e. changer = 2, tape = 3). The target LUNs for an auto-loader and tape drive that are Multi-LUN Based should be configured so that the target LUN for the tape drive is lower than the target LUN for the changer ( i.e. tape = 0, changer= 1)
---power-cycle the library and server
---Verify that the autoloader is in "Random" or "SCSI" Mode, not "Sequential" or "Automatic" mode. This can cause library errors in Backup Exec
---Make sure the tape device isn't connected to a RAID controller or sharing a SCSI bus with a hard drive
After performing the above steps, run an inventory and a small job, and let us know the outcome.
To isolate hardware related issue we suggest you to perform a test backup using Windows backup utility "NTBackup"
---Stop and Disable the Backup Exec services (if they're running)
---Run TAPEINST from the Backup Exec installation directory and choose to remove all Veritas drivers, but do not reboot.
---Using Device Manager, uninstall all the tape devices and medium changers To do this, right-click on each device and choose "Uninstall."
---Reboot the server.
---The server should come back up and detect the tape devices and install Microsoft drivers for them. If it doesn't, install the manufacturer's drivers for the device.
---Test Windows Backup to make sure the devices are functioning properly before proceeding. Backup Exec's services should not be started at all, nor should it be involved during this phase
Do let us know the outcome of the above steps performed.
