摘要： A method for facilitating input/output (I/O) communication for a processing operation is provided. An interrogate command is obtained by an I/O communications adapter. The interrogate command queries for status information of the processing operation to be provided in an interrogate response. A fixed number of resources and a time allocated to the interrogate command is throttled by pre-allocating the fixed number of resources needed for the interrogate command, and maintaining a timestamp for a interrogate message. The interrogate message is forwarded from the I/O communications adapter to a control unit. If the interrogate response is not received by the I/O communications adapter within a limited timeout period as measured by the timestamp, or if the interrogate message is received while the fixed number of pre-allocated resources are in use, the I/O communications adapter returns a busy response indicating the control unit is busy to prevent overrunning the control unit.
摘要翻译： 提供了一种用于促进用于处理操作的输入/输出（I / O）通信的方法。 询问命令由I / O通信适配器获得。 询问命令查询在询问响应中提供的处理操作的状态信息。 通过预分配询问命令所需的固定数量的资源以及维护询问消息的时间戳来限制分配给询问命令的固定数量的资源和时间。 询问消息从I / O通信适配器转发到控制单元。 如果I / O通信适配器在由时间戳测量的有限的超时时段内没有接收到询问响应，或者在固定数量的预分配资源正在使用时接收到询问消息，则I / O通信 适配器返回一个忙碌响应，指示控制单元正忙，以防止超控控制单元。

摘要： Provided are a method, system, and article of manufacture, wherein a primary storage control unit receives an information unit from a remote host over a fiber channel connection, wherein persistent information unit pacing is implemented over the fiber channel connection. Information is maintained on how many large writes have been received at the primary storage control unit over at least one logical path established over the fiber channel connection between the primary storage control unit and the remote host, wherein a large write is an input/output (I/O) operation for which a number of data information units that are processed exceeds a default value of an information unit pacing credit. The primary storage control unit adjusts an information unit pacing parameter included in a response sent from the primary storage control unit to the remote host, wherein the adjusting is based at least on the information maintained on how many large writes have been received at the primary storage control unit over the at least one logical path.

摘要： Method, system and computer program product embodiments for, in an input/output (I/O) link handling complex instruction chains, a messaging scheme incorporating a method of error recovery between an initiator processor and a receiver processor, are provided. An operation initiation message is been sent from the initiator processor to the receiver processor for the receiver processor to begin work on an operation. If determined to be necessary, a terminate operation message is sent from the initiator processor to the receiver processor. The initiator processor withholds sending additional messages for the operation until a terminate operation response message is received. Once the terminate operation message is received, outstanding messages in process are flushed from the receiver processor. The receiver processor withholds sending additional messages to the initiator processor as the outstanding messages are completed. The terminate operation response message is sent from the receiver processor to the initiator processor.
