I believe I had major problems in this implementation because I did the
Solstice disksuite installation first and then the Veritas install. This
hack probably is not compatible on metadisks but rather with plain
block/char devices like /dev/rdsk/c?t?d?s?

Cole pointed me to this website:

which seems to be the most respectable one from the lot.  

Other suggestions included upgrading to Veritas 4.0 which does not have
a rootdg dependency. According to my vendor it would not be a problem
since we're on Foundation Suite alternatively I believe it can be
arranged if you have a Sun disk array attached. 

On the issue of a null based rootdg ( zero cylinders in a slice) nobody
could confirm this. However I am still waiting for input from another
vendor who claimed this initially ( although this sounds like it might
have been a genuine miscommunication )

Thanks guys,
