# Adaptec AIC-7902b SCSI controller

So it happens I've stumbled uppon this controller. If you want to use Host RAID
feature like I wanted to, don't bother. Since it's proprietary feature, it's
not supported by GNU/Linux [more like an end of quotation here]. I found out in
one Fedora forum, I think, after looking around and wondering why do I see six
drives instead of one or three (RAID1/RAID10 + two spares).

Instead of Host RAID (which I recommend to disable) create nice and easy
software RAID with % mdadm; For example RAID5 or RAID6 is just fine, but RAID10
will do too :) Whatever works for you.

--- SNIP ---
# so you don't have to partition each drive
sfdisk -d /dev/sda | sfdisk /dev/sdb
...
mdadm -C /dev/md0 -l 6 -n 6 /dev/sda1 /dev/sdb1 ...
mkfs.ext4 /dev/md0

Some info about controller - it's Ultra320 SCSI, it supports RAID0, RAID1 and
RAID10 from four (4) drives and the rest as spares. In my case, it's connected
via 64-bit 133MHz PCI-X bus.
