2 wwn wwn Displays or sets the World Wide Name (WWN) of the switch. Synopsis wwn [name] Description Use this command to display the WWN of a switch. All switches have a numeric address that is the unique Fibre Channel address used for communicating with the switch. The WWN displays in the output of the switchShow command. WWNs must have eight colon-separated fields, each consisting of one or two hexadecimal digits between 0 and ff, with no spaces. After changing the WWN, this command prompts you to reboot the system (or switch on dual-domain systems), because the change does not take effect until the switch restarts. This reboot can be deferred, in which case you are expected to eventually use switchReboot or reboot to propagate the change to all switch components. However, the restart of the switch must happen before any firmwareDownload or (for bladed systems) CP failover occurs; otherwise, the behavior of the switch could be unexpected. This command cannot change the WWN of a switch in secure mode. When secure mode is enabled, this command can be issued only from the primary FCS switch. Operands none Examples To display the switch WWN and then change it: switch:admin> wwn 10:00:00:60:69:00:54:e9 switch:root> wwn 10:00:ff:ff:ff:80:02:3c The switch must be rebooted for the new WWN to take effect. Reboot now? (yes, y, no, n): [yes] y Rebooting switch 0 ... [system reboots] switch:root> wwn 10:00:ff:ff:ff:80:02:3c See Also switchShow 728 Fabric OS Command Reference Manual 53-1000436-01
