Use this command to enable or disable FICON emulation in an FCIP tunnel and
modify associated parameters on an FCIP tunnel on a VE_Port. A feature key is
required to enable any of the FICON emulation processing. The tunnel must be
down or disabled to issue and process the FICON commands. The results of this
command are persistent. The syntax for portCfg ficon is as follows:
portCfg ficon [slot/]Ge_Port tunnel_Id config | delete [FeatArgs] [ParamArgs]
This command has the following operands:
tunnel_Id
Specifies the tunnel ID for the configuration change. The valid range is 0 to 7.
config
Creates or modifies a FICON configuration.
delete
Deletes an existing FICON configuration.
The following optional feature arguments are supported with the config and
delete options. These configurations are persistent.
-x 1|0
Enables (1) or disables (0) XRC emulation. FICON XRC Emulation allows
XRC (IBM eXtendedRemote Copy, also known as IBM z/OS Global Mirroring)
to operate effectively at extended distances.
-w 1|0
Enables (1) or disables (0) Tape Write Pipelining. This feature improves the
performance of certain applications when writing to tape over extended
