I have just followed the sun guide to remove mirrored disks on a Solaris
2.8 V120 and now the box doesn't boot up!

The guide is as follows...
------------------------------------------------
How to Unmirror a File System That Cannot Be Unmounted (Command Line)
Use this task to unmirror file systems that cannot be unmounted during
normal system operation, including root (/), /usr, /opt, and swap.
The high-level steps for this procedure are:
* Running the metastat(1M) command to verify that at least one submirror
is in the "Okay" state
* Running the metadetach(1M) command on the mirror that contains root
(/), /usr, /opt, or swap to make a one-way mirror
* For /usr, /opt, and swap: changing the file system entry in the
/etc/vfstab file to use a non-DiskSuite device (slice)
* For root (/) only: running the metaroot(1M) command
* Rebooting the system
* Running the metaclear(1M) command to clear the mirror and submirrors
------------------------------------------------
I have two disks (c0t0d0 & c0t1d0) mirrored.
Disk 0 was corrupted and needed maintenance. I decided to break the
mirror using the method above, run metaroot to run from the second disk
i.e. metaroot c0t1d0s0.
I then modified vfstab so the other slices used the physical disk and
rebooted.
On reboot I now get ...
Could not install the ISA driver
Core dumps and then reboots
..and then reboots and reboots etc etc
Where do I go from here?
Any advice would be much appreciated
Thanks
