• Attached WWN: Click the radio button and, if a device is logged into the port, the
device’s WWN will display in the field. The device with this WWN or nickname will have
exclusive communication privileges to the port if WWN Binding is enabled.
If you click this radio button to bind the port to a logged-in device and there are no
devices logged in, the port is essentially bound to a WWN of “0.” This prevents any
device from logging in until this button is re-enabled to bind the WWN of a logged-in
device or until you explicitly bind the WWN of a device by clicking the WWN radio
button and entering a WWN or nickname (see the following). Changes only take effect
when you click the Activate button.
• WWN: Click the radio button and enter a world wide name (WWN) in the proper format
(xx.xx.xx.xx.xx.xx.xx.xx) or a nickname configured through the Product or Fabric
Manager applications. The device with this WWN or nickname will have exclusive
communication privileges through the port if WWN Binding is enabled.
Note the following:
– If you do not enter valid WWN or nickname in this field, but the WWN Binding check
box is checked (enabled), then no devices can communicate over the port.
– If you enter a WWN or nickname in this field and do not place a check in the WWN
Binding checkbox, the WWN or nickname will be stored, and all devices can
communicate over the port.
• Activate: Click to activate settings in this dialog box.
WWN Binding warning and error message display:
• If one or more of the nodes logged into a port does not match the WWN or nickname
configured in the field by the WWN radio button, a warning dialog box displays after you
activate the configuration. This warning box displays a list of all nodes that will be
logged off if you continue. If you Continue, these nodes will be logged off and the port
will only attach to the device with the device with the WWN or nickname configured in
the WWN field.
• An error message displays after you activate the configuration if the format for the
WWN entered in the WWN field is not valid (not in xx.xx.xx.xx.xx.xx.xx.xx format) or
if you have entered a nickname that was not configured through the Product or Fabric
Manager.
