    • An apparatus includes a cache memory for storing user data and control information of the apparatus, a nonvolatile memory and a processor for executing a process including when the power failure occurs, saving the user data and the control information stored in the cache memory into the nonvolatile memory, when the power failure recovers, restoring the data stored in the nonvolatile memory into the cache memory, and erasing the data stored in the nonvolatile memory after restoring the data into the cache memory and when another power failure occurs during erasing the data stored in the nonvolatile memory, erasing the control information stored in the nonvolatile memory if the control information is remained in the nonvolatile memory and saving, into the nonvolatile memory, the updated control information stored in the cache memory and the user data which has been erased from the nonvolatile memory.

    • In a storage system, a first reboot controller in a first control apparatus causes a second control apparatus to reboot, when it is detected that a second control apparatus has stopped access operations. The first reboot controller also places a boot event record in a non-volatile storage device of the second control apparatus to indicate that the rebooting of the second control apparatus has been caused by the first control apparatus. After that, a second reboot controller in the second control apparatus causes at least the first control apparatus to reboot while keeping intact the cache data stored in a cache memory of the first control apparatus, when the access controller of the first control apparatus is stopped while the second control apparatus is rebooted, and when a boot event record is found in the non-volatile storage device of the second control apparatus.
    • 在存储系统中,当检测到第二控制装置已经停止访问操作时,第一控制装置中的第一重启控制器使第二控制装置重启。 第一重新启动控制器还将引导事件记录放置在第二控制装置的非易失性存储装置中,以指示第二控制装置的重新启动是由第一控制装置引起的。 之后,当第一控制装置的访问控制器停止时,第二控制装置中的第二重启控制器至少使第一控制装置重新启动,同时保持存储在第一控制装置的高速缓冲存储器中的高速缓存数据, 重新启动第二控制装置,并且当在第二控制装置的非易失性存储装置中发现引导事件记录时。
