problem sles p620 with Ultra3 scsi raid

Hi list I am installing SLES on my pseries 620 and it works fine with both version (sles9-sp2 and sles8-sp3a) but I cannot see my disk arrays, I think that I need the apropiate driver for my raid card: PCI 4-Channel Ultra3 SCSI RAID Adapter, I can not find information about this driver for linux ppc... someone had have any similar experience? Another question, can I install Linux LPAR on this machine? I am thinking on this solution too.. Any advice please... thanks in advance Here my HW information and some information files: Pseries 620 (7025-6f1) 2-Way - RS64 IV 600 Mz 4MB L2 cache 02 internal disks scsi 01 PCI 4-Channel Ultra3 SCSI RAID Adapter with 5 scsi disks Tomas Carmen R.
