Well, the controller itself is supported, obviously (as an ATA controller), but I don't see that it is supported as a RAID controller. And, if this is the case -- ie: 1) the controller is indeed 6300ESB; and 2) it is supported as an ATA controller; but 3) it is not supported as a RAID controller -- then that would explain the situation described in the original message. That is: the system happily sees two individual ATA drives, but cannot see any array. This is all guesswork, but it makes sense. -- greg byshenk - [EMAIL PROTECTED] - Leiden, NL ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

The Intel 6300ESB (aka Hance Rapids I/O Controller Hub) serves as a controller for USB 2.0, UDMA100 and SATA150 devices. Separately of that, there's the Adaptec embedded SATA with Hostraid controller driver which comes into play if you activate RAID in the BIOS. Since they refer to it as Adaptec's Hostraid controller, it looks like ataraid(4) should support it. And No, I didn't have ataraid defined in my kernel. It was, but for some reason it isn't now. I'll uh, have to add and rebuild. Thanks for pointing out my error. Now, when the ar0s1a-f devices do show up, does the boot device actually get changed from ad4* to ar0* or do I need to boot single user while it's talking to ad4* and change the mount points and reboot? I've never played much with changing boot devices. --Bill ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

I've never played much with changing boot devices. loader(8) will parse the /etc/fstab of the partition it's on to find the root filesystem and use whatever device specification it finds there to pass to the kernel. To boot off the RAID, you'll need to change the fstab to the proper device.

I guess you'd have to look in the loader(8) manual and chapter 12 of the Handbook.
