    Abstract: PROBLEM TO BE SOLVED: To provide a method, a system, and a product for receiving a request from one of a plurality of hosts and process it by a controller.
    SOLUTION: The controller determines whether a primary storage control unit connected to the controller is operable or not. In response to the determination of the operability of a primary storage control unit, access is made to the primary storage control unit, and a response is generated. The response is generated when access is made to a secondary storage controller in response to the determination of the inoperability of the primary storage control unit, and data are synchronously duplicated from the primary storage control unit to a secondary unit control unit.

    Abstract: PROBLEM TO BE SOLVED: To provide a device, a system and a method for switching volume address association in point-in-time copy relationship. SOLUTION: A migration module 320 copies data from a source volume 205 to a target volume 210. A detection module 310 detects data corruption of the source volume 205. A switching module 315 switches a logical volume address from a source volume address of the source volume 205 to a target volume address of the target volume 210 in response to detecting the data corruption to redirect reading/writing of the data to the target volume 210. In one embodiment, a tracking module 325 tracks the current target volume copy of source volume data to redirect access for the source volume data without the current target volume copy to the source volume.

    Abstract: PROBLEM TO BE SOLVED: To provide a method, system, and program for write process management in which a list of destination location IDs during write operations is maintained in an array having an array pointer which identifies the next available entry of the array.
    SOLUTION: The method includes the steps of acquiring a location ID of a destination of a write operation, preserving the location ID in an available entry of the array, wherein the entry is identified by an array pointer having a first value, and changing the first value of the array pointer into a second value in order to identify other available array entries. Allowing a stack of variable sizes and adding a destination location ID of a pending write operation increases the size of the stack. Removing a destination location ID of a completed write operation reduces the size of the stack. A stack index may be incremented according as destination location IDs are added and may be decremented according as destination location IDs are removed.
