Raid troubles on openSUSE 11.3

i have an opensuse 11.3 machine with six HDDs. two of it is a raid-0 for system partitions, four for data (that mashine must be a file-server).
Motherboard is Gigabyte GA-P55A-UD3. Raid configured via its hardware options.
Now, in system i see all six HDDs, in partitioning i see my RAID-0 and four other. For that moment others disks configured as RAID-5. Why i can’t see them in SuSe enviroment?
