Zones
A zone is a named group of ports or devices that can communicate with each
other. Devices within a zone can only communicate with other in the same zone. A
device may participate in more than one zone.
Membership in a zone can be defined by switch domain ID and port number,
device Fibre Channel address, or device World Wide Name (WWN).
WWN entries define zone membership by the World Wide Name of the
attached device. With this membership method, you can move WWN
member devices to different switch ports in different zones without having to
edit the member entry as you would with a domain ID/port number member.
Furthermore, unlike FCID members, WWN zone members are not affected
by changes in the fabric that could change the Fibre Channel address of an
attached device.
