SCSI on v6.0

Hello;
I have installed FreeBSD v6.0 and all is fine so far. I had
the 
intention to install two SCSI drives in this
system after initial install to get it together step by
step. I have 
several Books on FreeBSD including the
hard copy manuals that are obtained from FreeBSD Mall, I.E.
user and 
admin manuals. Reading up
on the use of SCSI on FreeBSD i am instructed by one of the
books, I 
don't remember which right now
that I have to add a kernel option and rebuild the kernel
with SCSI 
support. But tonight I went ahead
and installed the adapter card, and the two drives and
booted to see if 
the hardware setup had any
complaints. All seems to be well with it but I can't even
hear the SCSI 
drives. I would expect 15k drives
to make some whining noise, maybe not. I am using LSI Logic
adapter 
card (haven't checked for
specific FreeBSD support).
On boot there was a line to the effect 'waiting for SCSI
device to 
settle'. This leads me to believe that
there may already be SCSI support in v6.0.
Q: Is this in fact true (v6.0 has SCSI support by default)?
None of the books are really current
enough for v6.0 specific info as such.

On the same subject,
Q: What is the best way to proceed with formating and
partitioning the 
drives?
Redo installation process, or is there away to set them up
without 
reinstallation?
I will want to assign one of the SCSI drives to the /usr
file system 
and the other
to the /var file system when the one ATA drive that is being
used has 
it all now.
Anyhow, I'm being lazy with this query and I do intend to
RTFM.
Thank you in advance;
Jeff k

You can check to see if your drive was detected via dmesg.
It should 
appear as daN (N being a number).

You can run sysinstall and set up new disks at any time.

device          mpt             # LSI-Logic MPT-Fusion
so typing
dmesg -a | grep mpt
should give you an indication if these are probing
and probing correctly.

For as long as I've been using (sic) FreeBSD, at least some
common SCSI has been in the GENERIC kernel.

sysnstall is easier for a newbie, bsdlabel and newfs are
much more flexible and much simpler once you understand
the syntax.

I would label and newfs the partitions, then:
mount /dev/da0a /mnt/usr
mount /dev/da1a /mnt/var
(you can't just type these in and expect them to work as
shown)
pax -r -w -p e -X /usr/ /mnt/usr
(same thing for var)
ee /etc/fstab
(you might also want to boot into single user mode to clear
the
old /usr and /var mount points, since they'll be redundant)
shutdown -r now and pray a lot.

Notes:  man pax, man bsdlabel, man newfs.  All very
important.
