摘要： A storage control unit detects a change in a configuration of a plurality of logical subsystems included in the storage control unit. The storage control unit sends a notification, wherein the notification indicates the change in the configuration of the plurality of logical subsystems. The storage control unit receives data transfer requests directed at available logical subsystems in the storage control unit, wherein the available logical subsystems are determined based on the configuration of the plurality of logical subsystems.

摘要： Provided are a method, system, and article of manufacture, in which a logical path is established between a control unit and a channel over a fibre channel connection. Code for persistent information unit pacing is loaded into the control unit and the channel. An indicator is set in node descriptors of the control unit and the channel to indicate concurrent enablement of persistent pacing while retaining the established logical path between the control unit and the channel.

摘要： A method for recovering from an error in a multi-core storage-system component is disclosed. In one embodiment, such a method includes detecting an error in a first core of a multi-core component. The method determines whether the error was one of (1) detected by the first core; and (2) detected by a core other than the first core. In the event the error was detected by the first core and the error is recoverable, the first core recovers from the error without substantially impacting operation of other cores in the multi-core component. In the event the error was detected by a core other than the first core and the error is recoverable, a core other than the first core recovers from the error without substantially impacting operation of other cores in the multi-core component. A corresponding apparatus and computer program product are also disclosed.

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： Provided are a system and article of manufacture for establishing and requesting status on a computational resource. An operation is performed to establish a computational resource, wherein the computational resource is not available until the establish operation is completed. A determination is made as to whether a status request to determine status of the computational resource is pending before the establish operation has completed. Indication is made to resubmit the status request if there is a status request for the computational resource pending before the establish operation has completed.

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.
