Well, if your disks were indeed used by the BIOS in IDE mode,
the SATA driver is not used, and you'd likely see the pci-ide
driver names like "cmdk" in your other disk names.

AFAIK the disks should be recognized automagically upon boot,
and if not - try running "devfsadm -Cv" to detect devices
and add/remove the links in /dev dir.

This usually means that your root/boot disk was also changed
from IDE to AHCI, and this does interrupt the boot procedure.
The lowlevel issue is that the driver and device names for
disks change, rendering invalid those names used in the rpool
config carried over to the miniroot image (boot_archive).

There are workarounds, likely posted in archives of zfs-discuss
list and many other sources. If I google anything good up, I'll
post a link here :)
