    • 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.
    • 本发明提供了一种在共享存储器中发生故障的情况下,控制伪通过操作的周期以减少磁盘阵列设备的性能下降的周期的技术。 将控制信息划分为需要双工的管理信息和仅需要进行单工的目录信息,并将管理信息和目录信息存储在单独的共享存储器中。 在存储目录信息的扩展存储器单元(Option)的共享存储器中发生故障的情况下,在基本存储器单元(Basic)的共享存储器中重新设置目录信息。 在重新建立目录信息时,伪通过操作被取消。 在扩展的存储器单元的包装被正常产品替换之后,目录信息被重新建立。 在另一个集群中管理的管理信息被复制到基础存储器单元的共享存储器中,以完成维护和恢复工作。
