    摘要: A disk subsystem assures the sequence and the coherence of data updating with two or more disk subsystems is provided with an asynchronous remote copy function. A main center 9 includes a computer system having the configuration of slave subsystems 3-2 to 3-n connected with a master disk subsystem 3-1. It secures the coherence between data at the main center 9 and the remote center 10 at the temporary suspension by repeating temporary suspension and release of the temporary suspension of the remote copy by the master subsystem 3-1 at predetermined opportunities. It also repeats temporary suspension and release of the temporary suspension of the remote copy by slave subsystems 3-2 to 3-n connected to it.

    摘要: A data storage system comprises a magnetic disk, an optical disk, optical disk drive units, and optical disk transport devices for transporting the optical disk to the optical disk drive units as required. The data storage system further comprises a host system for receiving and transmitting a command and data in the format of the magnetic disk and a converter for converting the command and the data between the format of the magnetic disk and that of the optical disk. The optical disk, the optical disk drive unit and the optical disk transport device are controlled by a command and data in the format of the magnetic disk of the host system.

    摘要: A buffer memory capable of storing contents of a plurality of tracks of a disk volume is provided in a disk controller or a disk drive, and in dump processing requested by a higher rank unit (CPU) to the disk controller, the data is immediately transferred from the buffer memory if the data to be dumped is present in the buffer memory, and if the data to be dumped is not present in the buffer memory, dump prefetching into the buffer memory is started and the execution of the dump processing is interrupted so that an on-line input/output operation other than the dump processing is accepted. When the dump prefetching into the buffer memory is over, the interrupted dump processing is resumed.

    摘要: In a data processing system having a first external memory, a second external memory, and a control memory for storing information on data renewals in the first external memory, a system and a method provide for back-up operations in parallel with ordinary data processing, including dump processing in which renewed data parts in the first external memory are copied as backup data into the second external memory with reference to the contents of the control memory. The method provides the step of storing into the control memory first identifier information for identifying areas of the first external memory where data items were renewed; the step of storing into the control memory second identifier information for identifying areas of the first external memory where data items were renewed during the dump processing; and the step of erasing at completion of the dump processing the first identifier information items except those which identify the same areas as identified by the second identifier information items. Thus, ordinary job processing and the renewals of the data items of the first external memory can be performed even in the course of the data dumping processing.
