Planning Considerations for Fibre Channel Topologies 3 7. Verify FICON devices are still logged in - Maximize the Element Manager application. Inspect the Node List View and verify FICON devices (channels and control units inspected in step 5) are still logged in to each director or switch. 8. Change switch binding enforcement if required - If the SAN environment is volatile (characterized by a high volume of optical cable connects, disconnects, and movement), change switch binding enforcement to restrict E_Ports only. a. At the Element Manager application, click the Hardware tab. At the Hardware View, select Switch Binding, then Change State from the Configure menu. The Switch Binding - State Change dialog box displays. b. Ensure the Enable Switch Binding check box is checked (enabled). c. Select (click) the Restrict E_Ports radio button to restrict connections from specific fabric elements to E_Ports. WWNs can be added to the membership list to allow fabric element connection and removed from the list to prohibit fabric element connection. Devices are allowed to connect to any F_Port or FL_Port without restriction. d. Click Activate to close the dialog box and enforce the connection policy. 9. Update channel path and control unit definitions - A cascaded FICON environment requires channel entry switch and link address updates to the input/output configuration program (IOCP) as follows: a. In the IOCP, define an entry switch ID in the SWITCH keyword of the channel path identifier (CHPID) definition. NOTE: An entry switch is a fabric director or switch connected to the FICON channel of a zSeries processor and a second fabric director or switch. b. In the IOCP, define a 2-byte link address (consisting of a switch (or domain) address and port address) for the cascaded switch in the LINK keyword of the control unit (CNTLUNIT) definition.
