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.
Operands none
