• A zone name cannot contain spaces. • Valid characters are all letters, all numbers, and the special characters A zone name can have a maximum of 64 characters. Using WWNs To identify a zone member by WWN, use the 16-digit WWN of the device. For example: 10:00:08:00:88:40:C0:D4 In the HP EFC Manager, Fabric Manager and Product Manager, the WWN is preceded with the switch or director manufacturer's name. The WWN is assigned to the Fibre Channel interface or HBA installed in devices such as servers or storage devices. Although the device may also have a node WWN, this WWN is not used for zoning identification. If you have assigned a nickname to the WWN through the Configure Nicknames dialog box, that nickname appears when you point to the WWN. In this case, you will assign the nickname as the zone member. The advantage of identifying a zone member as the WWN of the attached device is that the identification will not change if fiber cable connections to ports are rearranged. This is especially important if you are using spare ports. You can simply move the fiber cable to a spare port from a failed port and still maintain the zoning configuration. The disadvantage of identifying a zone member by the WWN is that removal and replacement of a device HBA or Fibre Channel interface (thereby changing the device WWN) disrupts zone operation and may incorrectly include or exclude a device from a zone. Using Port Numbers To identify a zone member by port number, use the domain identification number of the managed product and the port number on that managed product. For example: Domain 1, Port 1 Port numbers can be 0-n, with n representing the number of ports on the managed product, minus one. When you define a zone member by a port number, then any device attached 60 Zoning Concepts
