Hardware RAID controllers such as amr(4) or twe(4) (I've seen LSI MegaRAID SCSI 320-1 and 3Ware Escalade 8006-2 LP, the latter is a 2-port SATA controller and can't do RAID5 for lack of ports) stuff usually presents a whole logical unit as a single SCSI drive (/dev/da0 for the first disk array, /dev/da1 for the second and so on), so you shouldn't need vinum, geom or anything like that - just the driver would suffice. If you need vinum or geom to implement a RAID then chances are your so-called "hardware RAID" is actually fake (fakeraid) and really software RAID. Adaptec "HostRAID" and the RAID in intel's ICH x-R chipsets falls into this fakeraid category. The vendors don't like to present it as software RAID, so that particular bit is extremely hard to find :-( What is the brand and model of your so-called hardware RAID? -- Matthias Andree
