Abstract: In an exemplary storage system, a processor assigns an unused process to a read request designating an area of a logical volume. The processor determines whether the data designated by the read request is in a cache memory, based on a first identifier for identifying the area designated by the read request. When the designated data is not in the cache memory and a part of physical volumes providing the logical volume is a first kind of physical volume, the processor stores the first identifier associated with an identifier for identifying an area allocated in the cache memory. When the designated data is not in the cache memory and a part of the physical volumes is a second kind of physical volume, the processor stores a second identifier for identifying the process assigned to the read request associated with an identifier for identifying an area allocated in the cache memory.

Abstract: A migration-destination primary storage apparatus (MD-PDKC) comprises a second PVOL and a second journal storage area storing a journal corresponding to write data for the second PVOL, and executes a data copy to the second PVOL from a first PVOL, which is in a migration-source primary storage apparatus (MS-PDKC) and forms a copy pair with an SVOL in a secondary storage apparatus (SDKC). After the data copy has been completed, the MD-PDKC acquires the latest write sequence information from the MS-PDKC, and upon receiving a write request for the second PVOL, writes the write-request write data to the second PVOL, creates a journal by using journal data corresponding to the write data and also by using update information showing write sequence information based on the acquired latest write sequence information, and writes the journal to the second journal storage area.

Abstract: A primary storage controller determines that a quarantined area of the primary storage controller cannot be repaired, wherein the quarantined area is infected with a virus. A query is sent to a secondary storage controller to determine whether the secondary storage controller has data that is free of virus in an area of the secondary storage controller corresponding to the quarantined area of the primary storage controller. In response to receiving a notification that the secondary storage controller has data that is free of virus, the primary storage controller is repaired to remove the virus.

Abstract: A backup copy from a first data volume to a second data volume is executed according to either a synchronous mode, in which write data is copied from the first data volume to the second data volume in synchronous with a write request, or an asynchronous mode, in which journal data of a first storage apparatus is reflected on the second data volume in asynchronous with the write request. A second storage apparatus acquires secondary load information representing its own load status, and transmits the information to the first storage apparatus. The first storage apparatus acquires primary load information representing its own load status, determines switching between the modes based on the secondary load information, the primary load information and mode information, and transmits determination information representing determination results to the second storage apparatus. When the determination information represents the switching from the asynchronous mode to the synchronous mode, the second storage apparatus acquires the journal data from the first storage apparatus and reflects the journal data on the second data volume.
