SCSI problem on a IBM xSeries x206

[Marco Pizzi]

Hello,

I've a problem with a IBM xSeries x206 server.
This server is equipped with an Adaptec AIC7901 Ultra320 SCSI RAID card, 
and the two SCSI disks are
configured as RAID1 in the bios card.
I've installed FreeBSD 5.3, but the system go on to see the two SCSI disks 
(sd0 and sd1); not the logical RAID1
unit.
If I launch the command "pciconf -lv" the output is the following:

ahd0 at pci3:4:0:  class=0x010400 card=0x005f9005 chip=0x808f9005 rev=0x10 
hdr=0x00
     vendor   = 'Adaptec Inc'
     device   = 'AIC-7901 Ultra320 HostRAID Controller'
     class    = mass storage
     subclass = RAID

And, from the dmesg:

ahd0: <Adaptec AIC7901 Ultra320 SCSI adapter> port 
0x3000-0x30ff,0x3400-0x34ff mem 0xd0200000-0xd0201fff irq 2
7 at device 4.0 on pci3

Thanks,
