raid & label issues

[Max E. Kuznecov]

Hi,
I have a RAID1 created with atacontrol.
After installation I create a label, say: tunefs -L root /dev/ar0s1a
and put /def/ufs/root as rootfs into fstab.
So I expect the system will boot from raid (ar0s1a) device, but it
won't.

It occurs that tunefs create label not only on ar0 device itself but on
the raid components as well, in my case they are ad4 and ad6.

And after reboot I've got my system booted from ad4, i.e. the first
device with 'root' label on it. I've skimmed through the geom_label
sources and, indeed, it creates /dev/ufs/<label> entry for the first
device it tastes, and all the subsequent are ignored.

So the question is - is it possible to overcome this situtation and
force system to boot from right device?

My setup:

# uname -sr
FreeBSD 6.3-RELEASE

# pciconf -lv
atapci0 at pci0:31:1:	class=0x01018a card=0x24d08086 chip=0x24db8086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82801EB/ER (ICH5/ICH5R) EIDE Controller'
    class      = mass storage
    subclass   = ATA
atapci1 at pci0:31:2:	class=0x01018f card=0x24d18086 chip=0x24d18086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82801EB (ICH5) SATA Controller'
    class      = mass storage
    subclass   = ATA
