摘要： Methods, system and computer program product are provided to configure a path between nodes through a fabric in a fibre channel storage area network (SAN). A node name is provided for a target node on the SAN and a port name is provided for each port in the target node. A relationship is established in a data structure between each port name and a slot in which each port is physically located in the target node. Prior to configuring a path between a source node and a port in the target node, the ports which are physically connected and logged in to the fabric are identified by port address. The port names corresponding to the port addresses are then identified. The port names are used to generate interface_ids of the ports corresponding to the physical slots in which the ports are located. A data structure is created to maintain the relationship between interface_ids and port names. To establish a path connection between a port in the source node and a selected port in the target node, the node name of the target node and the interface_id of the selected port are input to the data structure and the port name of the selected port is output. The port name is then used to obtain the address of the selected port and an I/O session path opened between the source and target nodes.

摘要： A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.

摘要： An apparatus, system and method for synchronizing an asynchronous mirror volume using a synchronous mirror volume by tracking change information when data is written to a primary volume and not yet written to an asynchronous mirror, and storing the change information on both the primary storage system and the synchronous mirror system. In the event the primary storage system becomes unavailable, the asynchronous mirror is synchronized by copying data identified by the change information stored in the synchronous mirror system and using the synchronous mirror as the copy data source.

摘要： Tracks of data or other data units are copied from a primary storage system to a secondary storage system. For multiple-track or multiple-data unit transfers, a group of tracks or data units which are sequentially related are transferred. A respective task is defined at the primary storage system for monitoring a progress of the transfer of each of the respective data units in a group. A state is maintained for monitoring a progress of the transfer of the group responsive to the progress of each of the tasks. A normal state is selected when there are no failed tasks. A recovery state is selected when there is a failure, and the status of the remaining tasks is being ascertained. A retry state is selected following the recovery state to retry the failed tasks. A failed state indicates an unrecoverable failure.

摘要： A method of recovery from a data storage system failure in a data storage system having a host computer writing data to a first storage unit with a first storage controller synchronously mirroring the data to a second storage unit, and with a second storage controller asynchronously mirroring the data to a third storage unit. The method begins with the detection of a failure associated with the first storage unit. Upon detection of the error or failure associated with the first storage unit, the synchronous data mirroring relationship between the first storage unit and the second storage unit is terminated and the host is directed to write data updates directly to the second storage unit. Upon correction of the failure associated with the first storage unit, the asynchronous mirroring of data updates from the second storage unit to the third storage unit is suspended and synchronous mirroring of the data updates in a reverse direction, from the second storage unit to the first storage unit, is commenced. When a full duplex state is reached between the first storage unit and the second storage unit, the synchronous PPRC relationship with the first storage volume mirroring data to the second storage volume may be reestablished and host I/O writes to the first storage unit may be resumed.

摘要： Provided are a method, system, and program for managing resources in which a local processor sends remote operation requests to be executed by a remote processor having multiple resources. In the illustrated embodiment, the local processor and the remote processor each have a resource manager, each of which maintains a control set for each resource of the remote processor. Each control set of the remote processor resource manager includes a queue for queuing remote operation requests awaiting execution in connection with the resource associated with the control set. Each control set of the local processor resource manager includes a credit counter which keeps track of permissible outstanding remote operation requests. Each local processor control set credit counter is decremented for each remote operation request for the associated resource sent to the remote processor and is incremented for each acknowledgment received from the remote processor. For each remote processor control set, the remote processor resource manager sends an acknowledgment for each remote operation request initiated in connection with the associated resource. For each local processor control set, the local processor resource manager queues remote operation requests if the control set credit counter falls below a threshold after being initialized in accordance with the capacity of the associated remote processor control set queue.

摘要： Techniques are provided for performing a copy operation. An instant virtual copy operation is issued from a first portion of data to a primary mirroring portion of data, wherein the primary mirroring portion of data corresponds to a secondary mirroring portion of data, and wherein the primary mirroring portion of data and the secondary mirroring portion of data are in a mirroring relationship. The mirroring relationship is transitioned to a duplex pending state in response to determining that the mirroring relationship is in a full duplex state. When the mirroring relationship is in a duplex pending state, each block of data involved in the instant virtual copy operation is transferred from the primary mirroring portion of data to the secondary mirroring portion of data.
