You do with what you have as long as you have a Get Out Of Jail Free card
in your pocket. That is, a management-approved exemption from any
security requirement that you cannot fulfill w/o an ESM.

The chpid isn't important, per se, except that it dictates the WWPN. (And
with NPIV, each *subchannel* on the chpid gets its own WWPN.) You need to
know, in advance, the WWPN that the hosts will use and authorize them in
the SAN fabric.
Thanx Alan. Looks like I need to do some reading on NPIV. By the
way, I'm pretty sure, thos you have me second guessing, that if you
have several chpds on a frame, they all have the same WWPN which
comes from the machine.
