SiI 3512 raid1 set is not recognized

[Istvan Gabor]

Hello list members:

I am new on this list, but I have been using dmraid succesfully with my MB's nvidia nvraid.

Very recently I acquired a SiI 3512 PCI SATA raid card.
I created a RAID1 array on the card's BIOS using two hard disks of the same type (and size). The RAID array is recognized by the card's BIOS at boot.

Unfortunately the raid array is not detected by my openSUSE 11.2 system:

linux:~ # dmraid -s
no raid disks
linux:~ # dmraid -r
no raid disks
linux:~ # dmraid --version
dmraid version: 1.0.0.rc16-3 (2010.01.12)
dmraid library version: 1.0.0.rc16-3 (2010.01.12)
device-mapper version: 4.15.0
linux:~ #

linux:~ # ls -l /dev/mapper
total 0
crw-rw---- 1 root root 10, 60 Apr 24 20:17 control
linux:~ #

These modules, including sata_sil modules are loaded (lsmod):

dm_mod                 84900  0
sata_sil               10088  0

My dmraid version is:
linux:~ # dmraid --version
dmraid version:         1.0.0.rc16-3 (2010.01.12)
dmraid library version: 1.0.0.rc16-3 (2010.01.12)
device-mapper version:  4.15.0
linux:~ #

And my kernel is:

linux:~ # uname -a
Linux linux 2.6.31.14-0.4-desktop #1 SMP PREEMPT 2010-10-25 08:45:30 +0200 i686 athlon i386 GNU/Linux


If I boot knoppix live CD 6.2.1 on the very same harwdware the raid array is recognized by the knoppix system:

In knoppix the sata_sil driver is built in the kernel and not loaded as a module, I think.


Please help me how I could make openSUSE recognize the sil raid array?

Thanks is advance,

Istvan
