    摘要： A computer Input/Output system having a fabric, a control unit (CU) and a host computes including a channel, the channel having a channel port connected by a first link to a channel neighbor port of the fabric, and the control unit having a CU port connected by a second link to a CU neighbor port on the fabric. When an error is detected in the link or protocol between the channel and the control unit, after a retry of the failing operation is performed, error data are reported to the channel by the channel, the channel port, the channel neighbor port, the control unit, the Cu port and the CU neighbor port and sent to the channel. The error data are provided to the host computer for analysis.

    摘要： An apparatus, system, and method are disclosed for switching a volume address association in a point-in-time copy relationship. A copy module creates a point-in-time copy structure of a source volume at a target volume. A migration module copies data from the source volume to the target volume. A detection module detects data corruption in the source volume. A switch module switches a logical volume address from a source volume address of the source volume to a target volume address of the target volume in response to detecting the data corruption, redirecting data reads and writes to the target volume. In one embodiment, a tracking module tracks a current target volume copy of source volume data and redirects an access for source volume data without the current target volume copy to the source volume.

    摘要： Provided are a method, system, and article of manufacture for assigning alias addresses to base addresses. An assignment is provided of base addresses to the devices, wherein the base addresses are used to access the devices assigned to the base addresses. An assignment is provided of a plurality of alias addresses to an alias address pool. The alias addresses in the alias address pool are capable of being dynamically assigned to the devices to service I/O requests to the devices. An Input/Output (I/O) request to access one target device comprising one of the devices is processed. A determination is made as to whether the base address assigned to the target device is available. One alias address is assigned to the target device in response to determining that the base address is not available. The I/O request is issued to the assigned alias address to transmit the request to the target device.

    摘要： An apparatus, system, and method are disclosed for accessing a preferred path through a storage controller. A request module receives a request from a host to identify a preferred path from the host to a control unit image. A response module reports the preferred path to the host. A connection module connects the host through the preferred path to the control unit image. In one embodiment, a detection module detects a failure of a first interconnection module comprising the preferred path. The connection module may re-connect the host to the control unit image through a non-preferred path comprising a second interconnection module in response to the failure of the first interconnection module.

    摘要： A communication-path management system includes a path-detection component for identifying all communications paths between a host computer, through a controller, to a data storage device. Once identified, the communication paths are incorporated into a logical-path mask. The path-detection component recognizes each path as either preferred or non-preferred based on latency, bandwidth, availability, or other user-defined criteria and divides the logical-path mask into a preferred path subset and a non-preferred path subset. If a valid path exists in the preferred path subset, all communications from the host computer to the data storage device transit paths belonging to this subset. Otherwise, active control is given to the non-preferred path subset. A channel subsystem manages actual communication based on resource allocation and contention using the currently active subset.

    摘要： Provided are a method, system, and program for reassigning storage volumes from a failed processing system to a surviving processing system. A first processing system detects a failure of a second processing system. The first processing system determines device groups of storage devices managed by the failed second processing system and determines for each determined device group, hosts that connect to storage devices in the device group. The first processing system sends, for each device group, a unit check to each determined host indicating failure of each device group through one storage device in the device group to which the determined host connects. The determined hosts execute instructions to terminate any I/O operations in progress on the storage devices in the device group in response to the unit check indicating failure of one storage device in the device group and issue, a command to one storage device for the device group to end the busy condition.
