The 3ware 9000 driver from kernel 2.6.7-rc3-mm1 just creates one scsi device (is this case sdf) for my 4 disk RAID5 setup while the 3ware 2.6 driver from the install CD (tested with 2.6.5) creates sdf through sdm. Each drive corresponds to the same logical drive. Is this a driver bug or just a different approach? The in-kernel driver looks cleaner.
from 2.6.5 with 3ware driver from install CD:
