Neither.  It is a logical "vary" operation.  I'm being vague because you 
didn't say whether they were for CP's use (EDEVICEs) or Linux.  If these 
are CP-managed EDEVICEs, then when you VARY ON the subchannel (or if 
covered by Online_At_IPL in SYSTEM CONFIG), the virtual WWPN will light 
up.  If they are Linux's use, then they come online when you do the Linux 
equivalent of a "vary".
