submode to add the CUP to the appropriate zone.
Table 16-6 Cannot Enable FICON Port

FICON port.
Port is blocked. Unblock the port. Choose FICON > VSANs in Device
Manager, highlight the VSAN, and click Port
Configuration. Then unset the Block column, and click
Apply.
Alternatively, use the portaddress CLI command in
FICON submode and use the no block command.
TE or E port is prohibited. Change the TE or E port to disable prohibit. Choose
FICON > VSANs in Device Manager, highlight the VSAN
and click Port Configuration. Then uncheck the port
number column and click Apply.
Alternatively, use the portaddress CLI command in
FICON submode and use the no prohibit command.
Another port in the same VSAN has the
same port number as this port.
Change the port number to resolve the conflict.
Choose FICON > Port Numbers in Device Manager.
Alternatively, use the ficon slot slot number assign
port-numbers CLI command to change the port number.
