I have been attempting to install RHEL4 (update 3) on a dual-Opteron system with a 3WARE 9550SX RAID controller and 4 disks. I have configured it with one exportable unit as RAID5. I have forced a verify on this, yet the OS install disk will not recognise that any disks exist in the system that can be used for the install. According to 3WARE's website, I should not need a driver disk as long as I am using a release greater than U2 (which I am). In fact 3WARE does not provide a driver disk for RHEL4 U3. I have tried both 32 bit and 64-bit installs, with no success. During the install process, it prompts me to load additional drivers and I select the 3w-9xxxx driver. The system rescue live CD can find the exported RAID unit -- I was able to partition it when I booted from the System Rescue CD. Does anyone have any suggestions?
