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.
摘要翻译：提供了方法，系统和计算机程序产品，以通过光纤通道存储区域网络（SAN）中的结构来配置节点之间的路径。为SAN上的目标节点提供节点名称，并为目标节点中的每个端口提供端口名称。在每个端口名称和每个端口物理上位于目标节点的时隙之间的数据结构中建立关系。在目标节点中的源节点和端口之间配置路径之前，物理连接并登录到结构的端口由端口地址标识。然后识别与端口地址对应的端口名称。端口名称用于生成与端口所在物理槽相对应的端口的接口ID。创建数据结构以维护interface_ids和端口名称之间的关系。要在源节点中的端口和目标节点的选定端口之间建立路径连接，将目标节点的节点名称和所选端口的interface_id输入到数据结构，所选端口的端口名称为输出。然后使用端口名称来获取所选端口的地址以及在源节点和目标节点之间打开的I / O会话路径。

摘要： Provided are a method, system, and program for copying tracks between a primary controller and secondary controller. A track is received from the primary controller that is part of a copy job comprising a sequence of tracks to copy along with a sequence number of the received track and a context number identifying computational resources in the primary controller used to transmit the track, sequence number, and context number. The context number and sequence number transmitted with the track are used to determine if a track preceding the received track was written to storage. The secondary-controller writes the received track to storage if the track preceding the received track was written to storage.

摘要： Methods, system and computer program product are provided to improve the efficiency of data transfers in a PPRC environment. Any or all of three features may be implemented, each of which reduces the number of round trips required for the exchange of handshaking, data and control information. A first feature includes disabling the “transfer ready” acknowledgment which normally occurs between a primary storage controller and a secondary storage controller. A second feature includes pre-allocating payload and data buffers in the secondary storage controller. A third feature includes packaging write control information with a write command in an extended command descriptor block (CDB). Such a step eliminated the need for a separate transmission of the write control information. The CDB is transmitted along with a data block from the primary storage controller to the secondary storage controller and placed in the respective, pre-allocated buffers. Data may also be pipelined to the secondary. By decreasing the response time for data transfers, the distance separating the primary and secondary storage controllers may be increased.
摘要翻译：提供了方法，系统和计算机程序产品，以提高PPRC环境中数据传输的效率。可以实现三个特征中的任何一个或全部，每个特征减少交换握手，数据和控制信息所需的往返次数。第一个功能包括禁用通常在主存储控制器和辅助存储控制器之间发生的“传送就绪”确认。第二特征包括在副存储控制器中预分配有效载荷和数据缓冲器。第三个特征包括在扩展命令描述符块（CDB）中用写入命令封装写入控制信息。这样的步骤消除了对写入控制信息的单独发送的需要。 CDB与来自主存储控制器的数据块一起传送到辅助存储控制器并且被放置在相应的预先分配的缓冲器中。数据也可以流水线到次级。通过减少数据传输的响应时间，可以增加分离主存储控制器和辅助存储控制器的距离。

摘要： A method to provide information from a first information storage and retrieval system to a second information storage and retrieval system, where the first information storage and retrieval system comprises (N) PPRC adapters and information. The method generates and saves an Established Path Bitmap which recites the (N) PPRC adapters, and generates an Available Path Bitmap. If a PPRC adapter is in communication with the secondary storage system, then the method adds that adapter to the Available Path Bitmap. The primary information storage and retrieval system generates a PPRC task comprising a flag set to “off”. The method copies the Available Path Bitmap as a Working Bitmap, and generates a PPRC request comprising a flag set to “on”, selects one of the adapters recited in the Working Bitmap, and provides the PPRC request to that selected adapter. The method then once attempts to provide information to the second information storage and retrieval system using the selected adapter.
