Planning Considerations for Fibre Channel Topologies 3 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. NOTE: An cascaded switch is a fabric director or switch connected to a destination control unit and an entry switch. c. Run the IOCP to create an input/output configuration data set (IOCDS). The switch ID (CHPID macroinstructions) and 2-byte link address (control unit macroinstructions) are updated in the IOCDS. Refer to the IBM FICON Native Implementation and Reference Guide (SG24-6266) for additional information. 10. Verify FICON devices log back in - Inspect the Node List View and verify FICON devices (channels and control units inspected in step 5) log back in to the fabric as expected.
