440 Configuring and monitoring FCIP extension services
Where:
The following example shows FICON emulation on ge0 over tunnel id 1 with FICON XRC and tape write
pipelining enabled. The default values are assumed for wrtMaxPipe, wrtMaxDev, wrtTimer, and
wrtMaxChains.
portcfg ficon ge0 config -x 1 -w 1
slot The number of a slot in a 4/256 SAN Director or DC Director chassis that
contains an FR4-18i blade. This parameter does not apply to the stand-alone
400 Multi-protocol Router.
ge0|ge1 The Ethernet port used by the tunnel (ge0 or ge1).
tunnel_id The tunnel number (0 - 7).
config The config option creates a configuration.
-x 1|0 Enables or disables XRC emulation. 1 is enable, O is disable.
-w 1|0 Enables or disables tape write pipelining. 1 is enable, O is disable.
-r 1|0 Enables or disables tape read pipelining. 1 is enable, O is disable.
-t 1|0 Enables or disables TIN/TIR emulation. 1 is enable, O is disable.
-l 1|0 Enables or disables device level ACK emulation. 1 is enable, O is disable.
-b 1|0 Enables or disables FICON read block ID. 1 is enable, O is disable.
wrtMaxPipe value Defines a maximum number of channel commands that may be outstanding
at a given time during write pipelining. Too small of a value will result in poor
performance. The value should be chosen carefully based upon the typical
tape channel program that requires optimum performance. The default value
is 32. the range is 1-100.
rdMaxPipe value Defines a maximum number of channel commands that may be outstanding
at a given time during read pipelining. Too small of a value will result in poor
performance. The value should be chosen carefully based upon the typical
tape channel program that requires optimum performance. The default value
is 32. The range is 1-100.
wrtMaxDevs value Defines a maximum number of concurrent emulated tape write operations.
The default value is 16.The range is 1-32.
rdMaxDevs value Defines a maximum number of concurrent emulated tape read operations.
The default value is 16. The range is 1-32.
wrtTimer value Defines a time limit for pipelined write chains. This value is be specified in
milliseconds (ms). If a pipelined write chain takes longer than this value to
complete, the ending status for the next write chain will be withheld from the
channel. This limits processing to what the network and device can support.
Too small a value limits pipelining performance. Too large a value results in
too much data being accepted for one device on a path. The default value is
300 milliseconds (ms). The range is 100-1500.
wrtMaxChains value Defines the maximum amount of data that can be contained in a single
CCW chain. If this value is exceeded, emulation is suspended. The default is
3, which represents 3000000 bytes.
oxidBase value Defines the base value of an entry pool of 256 OXIDs supplied to emulation
generated exchanges. It should fall outside the range used by FICON
channels and devices to avoid conflicts. The default value is 0x1000. The
range is 0x0000 to 0xF000.
dbgFlags value Defines optional debug flags. The default is 0xF7C80000. This is primarily
for use by technical support personnel.
