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)

FICON F_Port to N_Port (or N_port to F_port)

FICON N_Port to

N_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.

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.

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.
