A friend of mine tries to install Linux on a IBM rack server machine, which has two hard disks and a aic 7902 SCSI/RAID controller. He has configured both disks as a RAID1 mirror in the BIOS. However, when booting Linux (SuSE or Knoppix), the kernel recognizes the controller and loads the aic79xx driver, but does not recognize the RAID mirror. Instead it presents both disks as separate disks /dev/sda and /dev/sdb. I could not find any documentation except that which comes with the kernel (Documentation/scsi/aic79xx.txt), but it doesn't say anything about RAID. Where could I find any hint about how to use RAID disks with aic7902 cards? regards Hadmut Danisch
