Swapping ports
Channel wrap on for port n dialog box
6. Click OK to enable channel wrapping for the port.
Use the port swap procedure to swap a device connection and logical
port address from a failed Fibre Channel port to an operational port.
Because both ports are blocked during the procedure, switch
communication with the attached device is momentarily disrupted.
To perform the port swap procedure for a pair of switch ports
(FICON management style only):
1. Notify the customer a port swap procedure will be performed
and a fiber-optic cable or cables will be disconnected. Ensure the
customer's system administrator quiesces Fibre Channel frame
traffic through the ports and sets attached devices offline.
2. At the EFC Server, open the EFC Manager application. The
Product View displays.
3. Select the icon representing the switch for which the loopback test
will be performed. The Hardware View for the selected switch
displays.
4. At the navigation control panel, select Swap Ports from the
Maintenance menu. The Swap Ports dialog box displays
