That's the expected behaviour :-/ The physical device path
for the root disk has changed by switching the S-ATA
controller between P-ATA emulation and AHCI mode, and
for that reason the root disk now uses a different device name
(e.g. /dev/dsk/c2t0d0s0 instead of /dev/dsk/c0d0s0).
The old device name that can be found in /etc/vfstab isn't
valid any more.
If you have no separate /usr filesystem, this can be fixed
with something like this:
- start boot from the hdd, this fails when trying to remount the
root filesystem in read/write mode, and offers a single user login
- login with the root password
- remount the root filesystem read/write, using the physical
device path for the disk from the /devices/... filesystem.
The "mount" command should show you the physical device
path that was used to mount the "/" filesystem read only.
Example for the remount command:
# mount -o remount,rw /devices/[EMAIL PROTECTED],0/pci1043,[EMAIL
PROTECTED]/[EMAIL PROTECTED],0:a /
- Run "devfsadm -v" to create new /dev links for the disks (on
the ahci controller)
- run "format"; the "AVAILABLE DISK SELECTIONS" menu should show
you the new device name for the disk
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c2t0d0 <DEFAULT cyl 48638 alt 2 hd 255 sec 63>
/[EMAIL PROTECTED],0/pci1043,[EMAIL PROTECTED]/[EMAIL PROTECTED],0
- now that we know the new disk device name, edit /etc/vfstab
and update all entries that reference the old name with the new
name
- reboot
