• Attached WWN—Click the option button for this option and, if a device is logged into the
port, the device's WWN displays in the field. The device with this WWN or nickname will
have exclusive communication privileges to the port if Port Binding is enabled.
If you click this option 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 option button and entering a
WWN or nickname (see the following). Changes only take effect when you click Activate.
• Detached WWN—Click the option 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 HAFM. The
device with this WWN or nickname will have exclusive communication privileges through
the port if Port Binding is enabled. Note the following:
• If you do not enter valid WWN or nickname in this field, but the Port 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 Port
Binding check box, the WWN or nickname will be stored, and all devices can
communicate over the port.
• Activate—Click to activate settings in this dialog box.
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 option 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 Element Manager.
• Clear Threshold Alert(s)—Click the Clear Link Threshold Alert(s) option on the port’s right-click
menu on the Port Card view and the Port List view to display the Clear Threshold Alert(s) dialog
box as shown in Figure 25 . Click the appropriate option to clear alerts for the selected port
only or all ports on the director. This clears all attention indicators that notify users of threshold
alerts in dialog boxes and views. This action also restarts the notification interval and the
cumulative minutes for utilization% interval.
