摘要： Before starting asynchronous remote copy in the multihop method (asynchronous remote copy from the first to the second storage apparatus to the third storage apparatus), a first and a second initial copy are performed. The first initial copy is a copy for making the contents of the first data volume in the first storage apparatus and the contents of the second data volume in the second storage apparatus consistent and the second initial copy is a copy for making the contents of the second data volume and the contents of the third data volume in the third storage apparatus consistent. In the second initial copy, the second storage apparatus creates a journal including the update number and the data in the second data volume, and the journal is transferred from the second storage apparatus to the third storage apparatus. The created update number is acquired from the first storage apparatus.

摘要： An object of the invention is to maintain conformability of data stored in a secondary storage system although a time stamp is not granted to write data received by a primary storage system. At least one of one or more computers includes a storage managing unit. The storage managing unit issues an ID next to an immediately previously issued ID to one or more primary storage systems (PDKCs) at regular or irregular intervals. Upon receiving a write command from one of the one or more computers, each PDKC prepares a journal (JNL) including a replica (journal data) of write data and the newest ID from the storage managing unit, and transmits the journal to a secondary storage system (SDKC). The SDKC stores a received JNL and reflects up to a particular JNL of non-reflected JNLs in a secondary volume. The particular JNL has an ID older by one than the oldest ID of the newest arrival completion IDs in one or more SDKCs.

摘要： The present invention provides a technique for, in the case in which a failure has occurred in a shared memory, controlling a period of a pseudo through operation to reduce a period in which performance of a disk array device falls. Control information is divided into management information, which is required to be duplexed, and directory information, which is only required to simplexed, and the management information and the directory information are stored in separate shared memories. In the case in which a failure has occurred in the shared memory of an expanded memory unit (Option) storing the directory information, the directory information is reestablished in the shared memory of a basic memory unit (Basic). The pseudo through operation is cancelled at the point when the directory information is reestablished. After a package of the expanded memory unit is replaced with a normal product, the directory information is reestablished again. Management information managed in the other cluster is copied to the shared memory of the basis memory unit to complete maintenance and recovery work.
