But prtvtoc has all that information, yes?

Is all you need the number in prtvtoc converted from blocks to
gigabytes?

Here's a perl one liner... It could be modified to present other
information, or information in a different format.

# prtvtoc /dev/rdsk/c0t0d0s0 | perl -lane 'next if /^\*/; $gb = $F[4] / (1024 * 1024 * 2) ; printf ("%u %5.2f %s\n", $F[0], $gb, $F[6]); '

The information is "slice#, size(GB), mountpoint".
