Correct.  From the man page:

     resetconfig
             The resetconfig command completely obliterates the vinum configu-
             ration on a system.  Use this command only when you want to com-
             pletely delete the configuration. 

I'm completely baffled that people want to use this command so much.
The correct sequence is to remove the drive, replace it with something
else with a Vinum partition, and then start the defective objects.

It depends on the volume structures as to whether the data can still
be recovered.
