I've seen this happen with LSI SAS RAID controllers. Typically to get "JBOD" behavior you just don't configure any RAID volumes and the controller will present each drive as a separate device. However, if you replace a drive, the controller seems to know that the new drive is not the same physical device (maybe it remembers the serial number) and presents a new target number instead of re-using the old one. I haven't had time to figure out exactly why this happens, but it's annoying and I'd love to understand it better.
