LUN Assignments for DLT 8000 Tape Systems and Control Ports in the tape library
In the tape library, the logical unit number (LUN) for the Sequential Access device is always LUN 0 of the drive. The LUN for the Medium Changer device is always LUN 0 of each control port (all other LUNs are invalid addresses). These devices are compatible with the SCSI-2 or SCSI-3 standard. For information about the SCSI commands for the tape drive and the library, see the Quantum DLT 8000 Tape System Product Manual or this manual.
