Configuring Xrc Acceleration; Moving A Ficon Vsan To An Offline State - Cisco MDS 9000 Series Configuration Manual

Configuring XRC Acceleration

Configuring XRC Acceleration
IBM z/OS Global Mirror eXtended Remote Copy (XRC) is supported on the MSM-18+4 modules. For XRC
to function, XRC acceleration must be enabled on the FCIP tunnel interfaces on both ends. XRC acceleration
is disabled by default.
To enable XRC acceleration, follow these steps:
Step 1 switch# config t
switch(config)#
Enters the configuration mode.
Step 2 switch(config)# interface fcip 2
switch(config)#
Specifies an FCIP tunnel interface and enters interface configuration submode.
Step 3
switch(config-if)# ficon-xrc-emulator
switch(config)#
Enables XRC acceleration over the FCIP interface.
Step 4 switch(config-if)# no ficon-xrc-emulator
switch(config)#
Disables (default) XRC acceleration over the FCIP tunnel interface.
Note XRC acceleration and FICON tape acceleration cannot be enabled on the same FCIP tunnel interface and cannot
exist in the same VSAN.

Moving a FICON VSAN to an Offline State

Issue the ficon vsan vsan-id offline command in EXEC mode to log out all ports in the VSAN that need to
be suspended.
Issue the EXEC-level ficon vsan vsan-id online command in EXEC mode to remove the offline condition
and to allow ports to log on again.
Note
This command can be issued by the host if the host is allowed to do so (see the
the Switch Offline, on page
Cisco MDS 9000 Series Fabric Configuration Guide, Release 8.x
288
265).
