1. Go to ok prompt.
# init 0
2. At ok prompt, boot the CD-ROM into single user mode.
ok boot cdrom -s
3. After booting, mount the root slice:
# mount /dev/dsk/c1t1d0s0 /a
4. Edit /a/etc/system file to delete everything between:
Begin MDD root info (Do not edit this line.) End MDD root info (Do not edit this line.)
5. Edit /a/etc/vfstab file to replace all the /dev/md/dsk entries to /dev/dsk.

6. Finally, boot the disk.
Note:
1. Careful when editing the /etc/vfstab, if you forgot the device to mount, check either below file:
/kernel/drv/md.conf /etc/lvm/mddb.cf /etc/lvm/md.cf
2. Please BACKUP /etc/system, /etc/vfstab, /etc/lvm/md.cf, /etc/lvm/mddb.cf, /kernel/drv/md.conf before edit.
