Configuring the Director
device can attachh to the port.) If Port Binding is disabled (the box
is not checked), any device can attach to the port, even if a WWN
or Nickname is specified in the WWN field.
◆
Attached WWN — This is the device currently logged in to the
director port. If this item is selected and Port Binding is enabled,
this device has exclusive use of the port.
If no device is logged in, no WWN appears on the Attached
WWN
line. If the user then enables port binding, the port will be
bound to a WWN of 0, essentially preventing any device from
logging in until binding is disabled,or the bound WWN is
updated to a new WWN setting.
◆
WWN — This entry allows you to enter a WWN (in the format
xx.xx.xx.xx.xx.xx.xx.xx ) or Nickname of a device that will be
bound to the port. If Port Binding is enabled, this device has
exclusive use of the port, even if another device is logged in. (If
binding is not enabled, this WWN/Nickname will be stored.)
If Port Binding is enabled and no attached node matches the
WWN/Nickname in the WWN field, a warning (Figure 5-8 on
page 5-20) appears. If you click Continue at that warning, any
node that is logged in will be logged out. If the device identified
in the WWN field logs in, it will become bound to the port and
will be able to communicate.
