<i>&gt; &gt; I have a Canon Canoscan 300 flatbed scanner, configured for LUN 03 and a</i><br>
<i>&gt; &gt; ncr810 SCSI host adapter.</i><br>
<i>&gt; &gt; My kernel is configured with generic SCSI support, and have found the</i><br>
<i>&gt; &gt; generic SCSI devices /dev/sga</i><br>
<i>&gt; &gt; through /dev/sgh. No, I'm not much of a SCSI expert, but assuming that</i><br>
<i>&gt; &gt; /dev/sgd correspondes with LUN 03,</i><br>
<i>&gt; </i><br>
<i>&gt; No. sga is the lowest-lun with a device in the system. </i><br>
<p>
Pardon me but are you guys referring to LUN's or SCSI ID's? They both<br>
matter but could cause a misunderstanding here.<br>
<p>
for those that don't know: LUN's is short for Logical Unit Number and is a<br>
subnumbering scheme for SCSI devices. For example my Panasonic PowerDrive<br>
is both CD player and PD station. It uses SCSI ID 3. But the PD uses LUN 0<br>
and the CD part does use LUN 1.<br>
<p>
SG devices are handed out per LUN so my SCSI bus has 6 generic devices in<br>
the kernel but only 5 physical devices on the bus (besides the card ;-).<br>
<p>
xcdroast can show this nicely to you (should you have it at hand).<br>
