Running the ludelete command gave me this error:
>>ludelete 10u6_disk2
System has findroot enabled GRUB
Checking if last BE on any disk...
ERROR: Last BE on disk
ERROR: This boot environment <10u6_disk2> is the last BE on the above disk.
ERROR: Deleting this BE may make it impossible to boot from this disk.
ERROR: However you may still boot solaris if you have BE(s) on other disks.
ERROR: You *may* have to change boot-device order in the BIOS to accomplish this.
ERROR: If you still want to delete this BE <10u6_disk2>, please use the force option (-f).
Unable to delete boot environment.
So I tried it with the -f option after I checked to make sure that /dev/dsk/c3t0d0 was in fact the correct disk ( booting off /dev/dsk/c3t4d0 ).
The next problem I ran in to was that it couldn't mount some zfs filesystems that it thought should be there but didn't exist anymore.

I manually edited /etc/lu/ICF.1 and cleared out all of the zfs mounts and re-ran ludelete which returned even though it was still upset about a few mounts.
