摘要： A method for dynamically enabling and disabling use of XFR_RDY is disclosed herein. In one embodiment of the invention, such a method includes receiving a write command at a target and determining whether XFR_RDY is enabled or disabled for the write command. In the event XFR_RDY is disabled, the method determines whether one or more buffers are available at the target. If at least one buffer is available, the method processes the write command by writing data associated with the write command to the one or more buffers. The method then returns information indicating the number of buffers that are still available at the target after completing the write command. A corresponding apparatus and computer program product are also disclosed and claimed herein.
摘要翻译：本文公开了一种用于动态地启用和禁用XFR_RDY的方法。在本发明的一个实施例中，这种方法包括在目标处接收写入命令，并确定写入命令是否启用或禁用XFR_RDY。在XFR_RDY被禁用的情况下，该方法确定目标是否有一个或多个缓冲区可用。如果至少有一个缓冲区可用，该方法通过将与写入命令相关联的数据写入一个或多个缓冲器来处理写入命令。该方法然后在完成写命令之后返回指示目标上仍然可用的缓冲器的数量的信息。本文还公开并要求对应的装置和计算机程序产品。

摘要： Various embodiments provide systems and methods for migrating data. One system includes a small computer system interface logical unit number (SCSI LUN) configured to store protected data, a processor, and memory configured to store a peer-to-peer remote copy (PPRC) application. The processor is configured to execute the PPRC application to modify the protection in transmitted data and received data. One method includes receiving unprotected data, utilizing a PPRC application to add protection to the data to generate protected data, and storing the protected data in a protected SCSI LUN. Another method includes receiving, at a protected SCSI LUN, a request to transmit protected data, utilizing a PPRC application to strip the protection from the protected data to generate unprotected data, and transmitting the unprotected data to an unprotected SCSI LUN.

摘要： A method to maintain write operation atomicity where a write operation crosses a data storage medium track boundary. The method supplies a storage controller comprising a host adapter, a processor, and a NVS. The host adapter receives from a host computer a write request and data. The method determines if the write request will cross a data storage medium track boundary. If the write request will cross a data storage medium track boundary, the method indicates to the host adapter that the write request comprises a two-track transfer, and writes the data to the NVS as the data is received. If the host computer fails prior to providing all the data to the storage controller, the method discards the data written to the NVS to ensure write operation atomicity.

摘要： A method, system, and computer program product to preserve data integrity in a mirror and copy environment is disclosed herein. In one embodiment, a method may include receiving a write command and data from a host device. The method may further include writing the data to a primary storage device and attaching a primary sequence number associated with the primary storage device to the write command, thereby providing a numbered write command with a command sequence number. The numbered write command may then be transmitted to a secondary storage device. The method may further include comparing the command sequence number to a secondary sequence number associated with the secondary storage device. If the command sequence number matches the secondary sequence number, then the command may be executed. Otherwise, it may be ignored.

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： A first unit and a second unit are provided in a multi-layer computing system, wherein the first unit is at a higher layer than the second unit in the multi-layer computing system, and wherein the first unit is a higher level unit and the second unit is a lower level unit. The higher level unit sends to the lower level unit, information to adjust a threshold for failure of components coupled to the lower level unit, wherein the higher level unit has more information on a degree of redundancy in the multi-layer computing system than the lower level unit. The lower level unit adjusts the threshold for the failure of the components, by using the information sent from the higher level unit.
