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.
