Use the Port Binding dialog box to set the following options:
• Port Binding—Click to place a check mark in the box and enable Port 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 the option button for this option and, if a device is logged into the
port, the device's WWN is displayed 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 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 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 a 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 in to a port does not match the WWN or nickname
configured in the field by the WWN option button, a warning dialog box is displayed 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, 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 is displayed 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 ( Figure 24 on page 70.) 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.
