Monitoring and Managing the Director • Port Binding-Click this check box to place check mark in the box and enable WWN binding for the port. When enabled, only a specific device can communicate through the port. This device is specified by the WWN or nickname entered into the Bound WWN field (either the Attached WWN or Detached WWN options). With the check box cleared, any device can communicate through the port, even if a WWN or nickname is specified in the Bound WWN field. • Attached WWN-Click this option 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 Port Binding is enabled. NOTE: 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 reenabled to bind the WWN of a logged-in device or until you explicitly bind the WWN of a device wgeb you click the Detached WWN option and by enter a WWN or nickname (see the WWN next). Changes only take effect when you click the Activate button. • Detached WWN-Click this option 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 Manager application. 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 this button to activate settings in this dialog box. 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 option, 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 click Continue on the warning box, 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. 2-24 director product manager user guide
