FICON Port
Configurations
An Edge 3000 FICON port can be a connection directly to one of the
following:
• a FICON N_port (a MVS FICON Channel Interface or a FICON
Control Unit FICON port)
• an E_port from a FICON capable FC Switch
• an F_port from FICON capable FC Switch
NOTE: FICON support is available at this time only over GigE IP WANs.
FICON ISL Extension
(E_Port to E_Port)
In this configuration, the Edge FICON interfaces are extending a
FICON ISL between two like switches (CNT to CNT or McData to
McData). No other switches have been validated at this time. The
CNT FICON Emulation Features can be enabled on this path if and
only if the device IO paths are configured correctly through the
Switch Configuration. If there are multiple ISLs between the pair of
switches, then vendor specific features governing data flows over
ISLs must be defined so that CHPID I/Os flow bi-directionally over
the same ISL.
When configuring a FICON path to be a FICON ISL, you must enable
the E-port (Cascaded ISL) FICON port option in UCM. A cascaded
connection will not correctly initialize without this option enabled.
FICON F_Port to N_Port
(or N_port to F_port)
In this configuration, the Edge 3000 FICON port is directly connected
to either the Channel Interface or a Control Unit interface on one side
and the other side is connected to an F_port on a FICON capable
switch.
When configuring a FICON in this configuration, you must not
enable the E-port (Cascaded ISL) FICON port option in UCM. A
N_port to F_port connection will not correctly initialize with this
option enabled.
FICON N_Port to
N_Port
In this configuration, the Edge 3000 FICON port on one side is
directly connected to a Channel Interface and the remote side is
directly connected to a Control Unit interface. This configuration is
defined the same as the F_port to N_port configuration described in
the prior section.
