In deployments, very often customers zone their storage based only on a zone-name and WWPN members. Typically this causes a need for the Zone-Vote Algorithm to be used, but that’s an approximation that requires the user to be consistent in Zone names, consistent in zone membership (ie anywhere one FA or HBA is used for an entity, all the others need to be used at the same time).

There are some cases where the WWN is entirely predictable; in such cases, the option “-w” to vict.jar (such as vict.jar -w 50060482B82F9654) shows a suggested nickname or alias such as “Symm-182500953-05bA” (per http://www.emcstorageinfo.com/2007/08/how-to-decode-symmetrix-world-wide.html) which can be leveraged to provide for missing nicknames.
