With two OpenVMS boxes on one fibre channel switch and assuming there 
are no plans to toss other random additional gear onto the same switch 
and the same SAN, zoning is irrelevent.

If you have just VMS boxes and that EVA, then you're using your SAN 
like a CI.  As a private storage connection.

As for why fibre channel configurations are zoned, see 
<http://en.wikipedia.org/wiki/Fibre_Channel_zoning>, 
<www.enterprisenetworkingplanet.com/netsp/article.php/3695836> and 
other applicable resources available via your preferred web search 
engine.

In general, zoning gets way more interesting as you toss more and more 
and different and disparate gear onto the switch, and it helps keep 
different environments from seeing or stomping on each other.
