Thanks for the many responses re: problem cloning a V880 running 
Solaris 10 8/07 (update 4) with patches from about a month ago.

My problem was, although I had done "touch /reconfigure", apparently 
that was not noticed since mounting of the root filesystem failed.

So, I did "boot cdrom -s" at the OK, then

   fsck -y -F ufs /dev/rdsk/c1t0d0s0
   mount /dev/dsk/c1t0d0s0 /mnt
   devfsadm -C -r /mnt
   halt
   boot -r

and the system booted successfully. Probably the "boot -r" would have 
been sufficient.

Since the source and target disks are identical, "dd" is sufficient 
to clone. If they were not identical, ufsdump/ ufsrestore plus 
installboot would probably be necessary.
