摘要： Provided are a computer program product, system, and method for supporting non-delivery notification between a switch and device in a network. A login with a switch is initiated including a test service parameter requesting a non-delivery notification service to cause the switch to return a non-delivery notification in response to a test path request indicating a destination node that is unavailable. Indication is made that the test service is available for the login in response to receiving a reply from the switch that the switch accepts the login with the non-delivery notification service. The test path request is sent to the switch to determine whether the destination node is available in response to determining that the non-delivery notification service is available for the switch login. The non-delivery notification is received from the switch in response to the switch determining that the destination node to which the test path request is directed is unavailable.

摘要： Provided are a method, system, and article of manufacture for credit depletion notification for transmitting frames between a port pair. Credits indicate a number of outstanding frames a first device may transmit to a second device. The credits are decremented in response to transmitting a frame to the second device. The credits are incremented in response to receiving a ready code from the second device indicating that the second device processed the transmitted frame. A determination is made as to whether additional credits are needed for communicating frames from the first device to the second device. A credit depletion notification is sent to the second device in response to determining that the additional credits are needed for communication with the second device.

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： 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 fibre channel connection, wherein persistent information unit pacing is implemented over the fibre 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 fibre 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： An apparatus, system, and method are provided for facilitating port testing of a multi-port host adapter. The present invention includes a scheduler that schedules execution of a plurality of threads to test a first port and a plurality of threads to test a second port of a multi-port adapter. The port test routine is divided into threads such that execution time and switching overhead is minimized. A multithreading module provides multithreaded execution of the plurality of threads such that the port test of the first port and the port test of the second port are performed in parallel. The apparatus further includes a communication module that takes the first port and the second port off-line. A third port remains on-line for Input/Output (I/O) communications that are multithreaded with the plurality of threads involving the first port and the second port.

摘要： A Transfer Progress Alert Module and a method for optimizing processing of a data transfer load, in a data communication system is provided. The data transfer load is divided in individual data blocks. The device and method simultaneously perform pipelined operations on different individual data blocks, thus optimizing the overlap of pipelined operations. The method includes initializing the transfer by selecting a pre-defined individual data block size and determining a key for selecting and monitoring transfers with transfer addresses within a pre-determined address region. The method then continuously repeats following steps until all monitored individual data blocks from the data transfer load are processed. First, the incoming individual data blocks are transferred on a bus between a peripheral device and a memory, and the Transfer Progress Alert module is used for monitoring the individual data blocks having transfer addresses determined to belong in the pre-determined address region. The TPA module is used to determine when each monitored transferred individual data block is ready for a post-processing operation, at least one post-processing operation is performed on the data, and the processed data is transferred to a peripheral device. The method and device may also be adapted for performing an error detection operation on the monitored individual data blocks transferred on the bus, for ascertaining the integrity of the transferred data.

摘要： A system and method for recovering from logical path failures is set forth. More specifically, when a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. Additionally, the system and method facilitates recovery of the failed logical paths by using a plurality of logical path masks. A first mask is referred to as an intermediate failure logical path mask and a second mask is referred to as a permanent failure logical path mask.
