Date: Thu, 30 Nov 2000 10:40:04 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: text/plain Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG The AAA-131 is merely a SCSI controller chip and a DMA controller/parity engine. It expects all RAID operations to be performed in a driver (or the on-board BIOS if running in DOS mode). That said, the array that you created from the BIOS utility has no meaning to FreeBSD, and only appears as the component disks. You can use vinum to perform software RAID on the disks (and not be limited to only the disks attached to the card), but you will not get any benefit from the DMA controller for RAID 1 and 5. There has been some thought given to writing a driver for the AAA/ARO cards using RAIDFrame, but I would not expect anything in the near future.
