Before installing Backup Exec, make sure that the robotic library hardware is configured properly as follows:
Make sure the robotic arm is set to "Random" mode. Refer to your robotic library documentation for more information.
If you have a multi-LUN robotic library, make sure that the controller card is set to support multiple LUNs (if supported).
If you have a multi-LUN robotic library, make sure that the target LUN for the tape drive is lower than the target LUN for the changer.
The SCSI ID of the robotic arm must precede the SCSI ID of the drives in the robotic library. You should not use 0 or 1 because these SCSI IDs are typically reserved for boot devices.
Make sure the inquiry strings match for the drive and the robotic library.
