immediately before your CDROM is mentioned.

Taking the first 3 numbers, calling them X, Y and Z (OP puts his
numbers in of course), do this:

echo "scsi add-single-device X Y Z 1" > /proc/scsi/scsi

I'm back - did a little more research offline (with the help of the above
good advice) - and so far have come up with partial success. Thanks very
much for the help, Tim.

Also, since I'm still quite new at newsgroups, please pardon any 'novice'
goofs that I may make... :) BTW, what is difference between my public and
private email? Is this where I've seen some people insert extra letters to
fool the spammers?

Anyway... here's what has happened:

After doing the above 'echo' steps the new proc file showed all 6 LUNs
then the 'hardware browser' showed all 6 as separate devices (scd0-scd5)
and pushed the IDE cdrom down from scd1 to scd6. (During this browse each
of the trays was loaded and unloaded - fairly time consuming process with
each disk getting spun up and read. I can live with that since it would
happen once at bootup.) No problem so far...

I then edited fstab to create the new mount instructions, with new
sub-directories in /mnt, for each of these devices and rebooted...

Alas, the entries in /proc/scsi/scsi don't 'stick' because I was left with
only two of the 7 mounts in fstab and /proc/scsi/scsi was back to the
original data - two devices. So... I'm guessing that the phrase 'probe all
LUNs' is a vital, missing link, yes?

I looked at the BIOS startup menus for the controller (BusLogic BT946C) but
nothing indicated any options for LUNs at that level. I learned elsewhere
that LILO/GRUB can be used to insert special commands and wondered about
'max_luns=x' - would this accomplish the same thing. I couldn't really
find out much more detail on this option.

I've also read about loadable modules... is there anything that I should
spend time in that area, or is this going to involve a rebuilding of the
kernal (something I've never done...yet)?

One other idea I had (I seem to know just enough to be dangerous to myself
<grin>) related to someone's comment about a script. If the previous echo
steps were put in a script, would they be accessed before fstab? I don't
have the foggiest idea of what I'm getting into in this direction, but it
sounded good in my mind! :)

And one final possiblity - I have a set of disks for Fedora Core 3 (will
have to change the IDE cdrom to a dvd drive and that's the main reason -
just lazy - that I haven't upgraded). But if I did, do I have the option
of getting the kernal configured during the installation?

OTOH, I could probably put this in a Win2000 machine (pardon my blasphemy)
but that seems like an unconditional surrender!! ;-)

Thanks, DrJim
