Enables or disables TIN/TUR emulation. 1 is enable, O is disable.This option should be
enabled when one or all of the following features are enabled:
• XRC emulation.
• tape write pipelining.
• tape read pipelining.
Enables or disables device level ACK emulation. 1 is enable, O is disable. This option
should be enabled when one or all of the following features are enabled:
• XRC emulation.
• tape write pipelining.
• tape read pipelining.
Enables or disables FICON read block ID. 1 is enable, O is disable.
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.
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.
Defines a maximum number of concurrent emulated tape write operations. The default
value is 16.The range is 1-32.
Defines a maximum number of concurrent emulated tape read operations. The default
value is 16. The range is 1-32.
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.
this value is exceeded, emulation is suspended.
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.
Defines optional debug flags. This is primarily for use by technical support personnel.
The default is 0xF7C80000.
Enable or disable Transport Lrc Hdr Check. 1 is enable, 0 is disable.
