CDOT Namespace /vol

How do I get my original "vol" namespace back on a new CDOT Server.   I did not use the 7MTT tool to build the new Server (Ontap v8.3).

I want to mount my original volumes back under:  /vol     So if I can not mount up root any longer and then perform a "mkdir vol"..... then how do I get this top level namespace "vol" back, without creating a dummy volume....?    Thanks!
