Your using Promise not vt8xxx. Which show up the sata's as normal ide devices i.e /dev/hdx). Like I mentioned some sata controllers do show the devices as scsi, (for whatever reasons). The Promise is true hardware raid so this is probably why. Whereas the vt8xxx is just an sata controller and thus is more like your standard atapi contoller chip. The SATA drives regardless are pretty much more like atapi ide drives than true scsi array discs. On Thu, 2004-06-17 at 11:47, Joe Landman wrote:

Nope not gong to happen. The drives SHOULD show up as hda/hdc(b)(Note that the second drive appears as hdc not b in my rig, probably somthing to do with the crazzy via bios...). They are just ide drives... not scsi. SATA is just a jacked up interface to ide devices. Some raid sata solutions implement scsi ontop for various reasons, this one doesn't..
All my SATA drives show up as scsi. I run a RAID0 nicely across a pair of raptors. As an FYI:
