摘要： Provided are a method, system, and article of manufacture, wherein in certain embodiments a first device determines a possibility of an invalidation of a second device, wherein the first device is coupled to the second device via a fabric. A query is sent from the first device to validate the second device, in response to determining the possibility of the invalidation of the second device. A determination is made, at the first device, whether to continue I/O operations from the first device to the second device based on receiving a response to the query within a time period.

摘要： Computer networks are provided with a resource efficient ability to generate link performance statistics. To calculate the average link utilization per I/O operation, a first counter accumulates the number of I/O operations processed by a link and a second counter accumulates the time required by the link to complete each I/O operation. The second value is then divided by the first value. The number of operations per second for a link may be computed by dividing the first number by a predetermined period of time and the average number of operations using the link may be computed by dividing the second number by the predetermined period of time. A third counter may be employed to accumulate the number of bytes transferred by a link during each I/O operation. Then, average size of an I/O operation may be computed by dividing the third number by the first number and the average bandwidth per link operation may be computed by dividing the third number by the predetermined period of time. Separate sets of counters are preferably associated with each of several link types associated with a single port, thereby allowing separate statistics to be generated for each link type. The generated statistics are useful for such activities as problem resolution, load balancing and capacity planning.
摘要翻译：计算机网络具有生成链路性能统计资源的资源有效能力。为了计算每个I / O操作的平均链路利用率，第一计数器累加由链路处理的I / O操作的数量，并且第二计数器累加链接完成每个I / O操作所需的时间。然后将第二个值除以第一个值。可以通过将第一个数除以预定时间段来计算每秒链接的操作次数，并且可以通过将第二个数除以预定时间段来计算使用该链接的平均操作次数。可以使用第三计数器来累积每个I / O操作期间由链路传送的字节数。然后，可以通过将第三个数除以第一个数字来计算I / O操作的平均大小，并且可以通过将第三个数除以预定时间段来计算每个链接操作的平均带宽。单独的计数器组优选地与与单个端口相关联的几个链路类型中的每一个相关联，从而允许针对每个链路类型生成单独的统计信息。生成的统计信息对于解决问题，负载平衡和容量规划等活动非常有用。

摘要： Provided are a method, system and article of manufacture, wherein in certain embodiments an I/O command from a host is received at a first storage unit. An identifier is generated that identifies a destination to which the I/O command is to be transmitted from the first storage unit. The I/O command is augmented with the generated identifier at the first storage unit. The augmented I/O command is transmitted. In certain other embodiments, an I/O command is received at a storage unit, wherein the storage unit is associated with a storage unit identifier. A determination is made at the storage unit, whether the I/O command is associated with an identifier that identifies a destination for which the I/O command is intended. A further determination is made, at the storage unit, whether the identifier is the same as the storage unit identifier, in response to determining that the identifier associated with the I/O command identifies the destination for which the I/O command is intended.

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 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。
