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.

ote

When secure mode is enabled, this command can be issued only from the primary FCS switch.

Operands none
