| Problem with multiple scsi adapters and
drive assignments |

2008-03-18 17:37:30 |
I've searched all over (not totally exhaustive, but close)
and can't find an
answer that I thought would have come up before. Basically,
I need to
change the order that the kernel assigns drive names on
bootup.
It all started out with an old Intel server board with
NCR/Symbios scsi
builton. I added a QLogic QLA2100 fibre controller and
everything was fine
except that it was a little slow and couldn't hold enough
ram. I took
another (newer) Intel server board and put it in the case.
This board has
an Adaptec AIC7896 builtin. My custom kernel didn't have
the aic driver so
I took the opportunity to upgrade to 7.0 and built a new
kernel. Everything
was fine until I turned on the external fibre chassis and
found that my da0
became da7. The board is in a rack-mount case so I cant put
the QLA into a
different slot and the bios doesn't have any way to change
irq settings on
the pci slots.
I my mind, the logical answer is to tell FBSD to scan ahc0
before isp0.
Through all my searching through docs and the mailing list
archives, I can't
find any mention of how to do this. I did find one mention
of turning off
the bios on the offending scsi card (it was a system with 2
Adaptecs). Been
there, tried that, didn't work. Feel free to slap my face
and call me
stupid as long as you point my to the proper info if I
somehow missed it.
Here are the relevant parts of dmesg if that helps (I didn't
include the
drives themselves since I can't get it boot with the
external chassis turned
on):

This is exactly what labeling your disks solves.
Please see info on 'tunefs' and 'glabel' which provide
labels to
devices. Basically, when you insert a device not only does
it get its
scan-order-based /dev/___, it also gets a named entry in
either
/dev/ufs/ or /dev/label (tunefs/geom).
You then use the label to mount the drive.

The solution is not to change the order in which things are
probed, but to
hard-wire which name is assigned to which disk.
See the SCSI(4) manpage for information on how to do this by
setting hints
in /boot/device.hints.

I love it when I get multiple answers that are great looking
answers. My
personal preferences told me to try this one first. My
system is now up and
running correctly. I will keep both of these answers in my
mail archives
and the next time I add some drives, will try Patrick's
answer.
Thank you for a quick response.
