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： 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.

摘要： A method for combining partial records into a single direct memory access (DMA) operation for a count key data (CKD) protocol in a computer environment is provided. In an initiator processor of the computer environment, a number of the partial records to be prefetched is determined by gathering a plurality of descriptor information for a command according to a predetermined algorithm having a plurality of assumptions for the command. The number of partial records is prefetched. At least one of record headers and record keys of the number of partial records are concatenated into the single DMA operation. The DMA operation is forwarded to a receiver process to be completed.

摘要： A method is provided to protect against ill-behaved microcode by balancing between an actual occurrence of a hardware problem and a microcode bug setting a flag appearing as a hardware problem. In this method, the error recovery is performed only on a single piece of hardware and no further error recovery action is taken on other pieces of similar hardware. The approach addresses the problem by treating a hit on one card as a hardware problem, but as a bug on subsequent cards. The invention keeps track of whether or not the same event has occurred on the same type of hardware so not to take action on more than one instance of the hardware. Subsequent hits on another instance of the hardware will not trigger the hardware related recovery on additional hardware.
摘要翻译：提供了一种通过平衡实际发生的硬件问题和设置出现为硬件问题的标志的微代码错误来防止不良行为微代码的方法。在该方法中，仅在单个硬件上执行错误恢复，并且不对其他类似硬件进行进一步的错误恢复操作。该方法通过将一张卡上的打击视为硬件问题来解决问题，但是作为后续卡上的错误。本发明跟踪相同类型的硬件上是否发生了相同的事件，所以不对多个硬件实例采取行动。在另一个硬件实例上的后续命中不会触发额外硬件上的硬件相关恢复。

摘要： A method of packaging a plurality of repeating commands for device command word (DCW) processing in a computer environment having an I/O link handling complex instruction chains for a processing operation is provided. Locate record information is packaged into DCW prefix parameter data. The locate record information includes an intent count argument. The plurality of repeating commands are embedded as a truncated concatenation to the first locate record information. The plurality of repeating commands are identified by redefining the intent count argument for the plurality of repeating commands as a repeat count argument using a flag argument incorporated into the locate record information. The repeat count argument indicates a number of times for a control unit in the computer environment to execute the plurality of repeating commands.

摘要： A method of packaging locate record commands for device command word (DCW) processing is provided. A first locate record command is packaged into DCW prefix parameter data. The first locate record command includes first search and first seek arguments, a first intent count argument, a first transfer length factor argument, and a plurality of remaining arguments. A plurality of truncated locate record commands is embedded in the DCW prefix parameter data as concatenations to the first locate record command. Each of the plurality of truncated locate record commands include a unique search argument, intent count argument, and transfer length factor argument. Seek argument parameters for each of the plurality of truncated locate record commands are calculated by taking an offset from the first seek argument and the first search argument, applying the offset to each of the plurality of truncated locate record commands. The plurality of remaining arguments is shared.

摘要： A method for identifying the cause of degraded I/O performance between a host system and a storage controller includes initially monitoring I/O performance between the host system and the storage controller. The method further detects degraded I/O performance between the host system and the storage controller using any suitable technique. Once degraded I/O performance is detected, the method determines the cause of the degraded I/O performance by analyzing historical configuration records in the storage controller. These historical configuration records enable the storage controller to correlate the degraded I/O performance with configuration changes in the storage controller and/or the connected host systems. The method then notifies one or more host systems of the cause of the degraded I/O performance. A corresponding apparatus and computer program product are also disclosed herein.

摘要： An apparatus, system, and method are disclosed for detecting mismatches in a mirror volume. A receive module receives a start indicator from a primary storage system. The start indicator includes a starting location of a first block to be modified on a track in a secondary storage system. The first block corresponds to an identically located first block of a modified record in the primary storage system. The tracks the first blocks on the primary and secondary storage systems each comprise irregular count key data (“CKD”) tracks. A compare module compares the first block location indicated by the start indicator with block locations listed in track metadata. The track metadata describes user records on the irregular CKD tracks of the secondary storage system. An alert module generates an alert in response to the first block not aligning with a beginning block of a record on the secondary storage system.
