摘要： Provided are a method for selecting a path comprising ports on primary and secondary clusters to use to transmit data at a primary volume to a secondary volume. A request is received to copy data from a primary storage location to a secondary storage location. A determination is made from a plurality of primary clusters of an owner primary cluster for the primary storage location, wherein the primary clusters are configured to access the primary storage location. A determination is made as to whether there is at least one port on the owner primary cluster providing an available path to the secondary storage location. One port on the owner primary cluster is selected to use to copy the data to the secondary storage location in response to determining that there is at least one port on the owner primary cluster available to transmit to the secondary storage location.

摘要： Disclosed is a technique for fault isolation. A first error check is performed on a block of data in storage to determine whether the block of data was corrupted after the block of data was transferred from memory to the storage. When the first error check indicates that the block of data was corrupted, a second error check is performed using the block of data in the memory to determine whether the block of data was corrupted before being transferred from the memory. When the second error check indicates that the block of data was corrupted before being transferred from the memory, it is determined that the block of data was corrupted before being stored in the memory. When the second error check indicates that the block of data was corrupted after being transferred from the memory, it is determined that the block of data was corrupted by at least one of the memory or a formatter that performed the transfer.Additionally disclosed is a technique in which a block of data is transferred from a memory at a first control unit to a memory at a second control unit. At the first control unit, when a second error check at the second control unit indicates that the block of data was corrupted before being transferred from the memory, a third error check is performed on the block of data in memory at the first control unit. When the third error check indicates that the block of data was corrupted, it is determined that the block of data was corrupted at the first control unit. When the third error check indicates that the block of data was not corrupted, it is determined that the block of data was corrupted during transfer from the first control unit to the second control unit.
摘要翻译：公开了一种用于故障隔离的技术。对存储器中的数据块执行第一个错误检查，以确定在数据块从存储器传输到存储器之后数据块是否已损坏。当第一个错误检查指示数据块被破坏时，使用存储器中的数据块执行第二个错误检查，以确定在从存储器传送之前数据块是否已损坏。当第二个错误检查指示在从存储器传送之前数据块被破坏时，确定数据块在存储在存储器中之前被破坏。当第二个错误检查指示在从存储器传送之后数据块被破坏时，确定数据块被执行传送的存储器或格式器中的至少一个损坏。另外公开了一种技术，其中数据块从第一控制单元的存储器传送到第二控制单元处的存储器。在第一控制单元处，当第二控制单元的第二错误检查指示在从存储器传送之前数据块被破坏时，对第一控制单元的存储器中的数据块执行第三错误检查。当第三个错误检查指示数据块被破坏时，确定数据块在第一个控制单元被破坏。当第三错误检查指示数据块未被破坏时，确定在从第一控制单元传送到第二控制单元期间数据块被破坏。

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.
