[. . . ] When in LUN mode, the jukebox controller ID uses LUN 0 for itself and assigns the drives on Bus 1 to LUNs 1 to 4 or LUNs 1 to 6 (depending on whether you have four or six drives on Bus 1 in your model of the jukebox). The result is that there are two types of devices (controller and drives) at ID 6. Some host computer systems do not allow you to assign different device types to the same ID. If your host computer system does not support multiple types at the same ID and you want to use LUN mode, you must select different IDs for the jukebox controller (JKBX ID #) and the drives (DRV #). Tables in Appendix B show jukebox default settings and an example of setting the jukebox controller and drives to different IDs (one digit apart). If another device ID is placed between the jukebox controller and the drives, problems can result. For this reason, the jukebox will not accept IDs for the jukebox controller and drives that are more than one digit apart. Press NEXT or PREV until the new ID that you want displays and then press ENTER. If the jukebox is set to LUN MODE ON, go to Step 8. Only one ID can be changed and the ID automatically updates when you press ENTER. (If using basic SCSI addressing - LUN mode OFF) Press NEXT until UPDATE displays, and then press ENTER. UPDATE or WAIT FOR UPDATE and then ID'S SAVED displays briefly. · · If the new settings do not conflict with other SCSI IDs on the bus, SCSI ID'S displays. If the new settings conflict with other IDs on the SCSI bus, CONFLICT-ABORTED displays briefly and then VIEW ID'S displays. Any changes entered are lost, and you must repeat steps 3 through 6 to set a new ID. NOTE When in LUN mode: If the new ID you choose results in the IDs for the jukebox controller and the drives being more than one digit apart, the jukebox displays CONFLICT and rejects the ID. Press CANCEL until READY displays. 3-18 Chapter 3 Operating the Jukebox Setting the SCSI IDs CAUTION Turning off the jukebox in the next step could cause data loss if not done correctly. Do not turn off power to the jukebox until you are sure the SCSI bus is inactive. Removing power from a SCSI device when the bus is active can result in data loss and/or indeterminate bus states. Check your host system manuals for information about checking the SCSI bus status. If your computer is connected to a LAN, be sure to check with your system administrator before turning off power to the jukebox. Turn the jukebox OFF, then ON to save the IDs to the jukebox flash ROM.
