At some point, you may want to "capture" an existing installation of Solaris 10. One feature of Solaris that I found useful is the LiveUpdate functionality. This allows you to create a backup image of one or more partitions. It then keeps track of the locations should you need to boot that backup image state.
This is really useful for several reasons. First, you may want to capture the installed state of a given system. Should something go wrong, for example add a bad patch, you could just boot back to that given state.
In the case below, I am formatting a local disk to be my backup disk. I'm running the format utility to repartition the drive to have a single partition (also known as a "free hog") for the whole spindle.
# format -e
select disk 2
modify: set slice 6 to free hog.. the rest set to zero GB
Next.. I'm adding a UFS file system to that spindle. We will need this because the lucreate will need to run "cpio".
# newfs /dev/dsk/c1t1d0s6
newfs: construct a new file system /dev/rdsk/c1t1d0s6: (y/n)? y
Warning: 2496 sector(s) in last cylinder unallocated

143136800, 143235232, 143333664
The final step.. the LiveUpdate itself. In this case, I'm copying the whole "/" partition onto my newly created disk "
/dev/dsk/c1t1d0s6". This will do the copy on to the new disk. I'm also specifying that the target will support UFS. And the final "-n" will place a label for my boot parameter "newbootenv".
