Hi.
I had a working raid array in an Intel ICH9R controller with the two
volumes working ( ok in windows and mandriva 2008 livecd).

I booted the Opensuse 10.3RC2 live cd and did "dmraid -ay" and got the
following errors:

ERROR: isw device for volume "RAID0" broken on /dev/sda in RAID set
"isw_bbcfceegje_RAID0"
ERROR: isw: wrong # of devices in RAID set "isw_bbcfceegje_RAID0"
[1/2] on /dev/sda
ERROR: isw device for volume "RAID1" broken on /dev/sda in RAID set
"isw_bbcfceegje_RAID1"

ERROR: isw device for volume "RAID1" broken on /dev/sdb in RAID set

ERROR: no mapping possible for RAID set isw_bbcfceegje_RAID1
ERROR: no mapping possible for RAID set isw_chgffgbhfa_RAID1

Now in the intel bios it says the disks are offline.
The livecd must have a bug that destroys all raid arrays. I think the
problem is in device-mapper, because I did "dmraid --version" and the
device-mapper was "unknown". In mandriva it is 4.11.0. Dmraid is rc14
in both.
I don't have any logs from the live boot because the network was not working.

Is there any way to recover the raid volumes? I can provide you with
all the files needed, just ask.

Thanks
