You're right!

nas# gpt show wd3
       start        size  index  contents
           0           1         PMBR
           1  3907029134
  3907029135          32         Sec GPT table
  3907029167           1         Sec GPT header
nas# gpt destroy wd3
nas# gpt show wd3
       start        size  index  contents
           0           1         PMBR
           1  3907029167
nas# gpt create wd3
nas# gpt show wd3
       start        size  index  contents
           0           1         PMBR
           1           1         Pri GPT header
           2          32         Pri GPT table
          34  3907029101
  3907029135          32         Sec GPT table
  3907029167           1         Sec GPT header
nas# gpt add -s 10486224 -t swap -i 1 wd3
Partition added, use:
        dkctl rwd3d addwedge dk<N> 34 10486224 <type>
to create a wedge for it
nas#
