Zones in Solaris 10

We have a server loaded with Solaris 10 x86.

I am trying to create few zones on that. It was ok for the very first one.
Now it is a small confusion.

This is the out put.

# zoneadm list -vc
ID NAME STATUS PATH
0 global running /
- asterisk_zone configured /opt/home/srao/asterisk-zone
- mysql-zone configured /opt/home/srao/mysql-zone
- sql-zone configured /opt/home/srao/sql-zone
- psql-zone incomplete /opt/home/srao/psql-zone

Pl...Pl let me know any clues to delete the non-global zones. Believe me I am fed up with google.ca/docs.sun.com and various recommended steps like halt/uninstall/shutdown and delete.I have done whatever I can. Also I am not able to create fresh zones. I want to start once again after deleting these configured and incomplete zones. Every suggestion/related links for the deletion of the above mentioned zones and creation of new zones are welcome.Sun's docs are not useful to delete the above mentioned zones.

Your help is appreciated.

Thanks in advance
