For example, a tape drive with a tape changer could have the tape drive as one LUN, and the changer as another LUN, but they both use the same SCSI device number. Another possibility is a LUN controller with multiple IDE CD/DVD ROM drives attached. Each drive would be a separate LUN on the same SCSI device number. Sometimes you will run into a CD changer CD drive with each disk having its own LUN. (I had a 5 disk changer that worked that way.) Without knowing you hardware, we can not tell you what device you are looking at. But there should be a group of lines in /proc/scsi/scsi with the first line listing the controller card, the channel, the SCSI ID, and the LUN. There should be a description of the device below that. All the listings that have the same controller, channel, and ID, but differing LUNs should be the same hardware device. Look at the descriptions.
