Lets hope his docs are that complete. Joshua, I've got this faint echo running around in the back of my mind from something over a year ago, maybe even 2, where someone was having trouble with an HP that was responding to multiple LUNS. At the time I can't recall if the consensus was an HP bug, or a kernel bug. In this gents case I think I'd name /dev/nst0 as the drive, and /dev/sg3 as the changer so he is using the LUN=0 device for the drive, and the LUN=1 for the robotics. Only if there are weird results would I change it to /dev/sg2 for the robotics since that theoreticly would be the same as /dev/st0 at bus address 0,4,0. And that would make me nervous/apprehensive/worryalot etc. This one sort of caught me off-guard because here, /dev/nst0 at LUN 0 is the drive, and /dev/sg1, same bus address but LUN=1 is the robotics. Seagate 4586NP or CTL-96, it has lots of (re)badges on it. The cdr/w is of course /dev/sg0. -- Cheers, Gene AMD [EMAIL PROTECTED] 320M [EMAIL PROTECTED] 512M 99.26% setiathome rank, not too shabby for a WV hillbilly Yahoo.com attornies please note, additions to this message by Gene Heskett are: Copyright 2003 by Maurice Eugene Heskett, all rights reserved.
