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.
