Abstract

PURPOSE:To attain the data saving action of all data storing parts under the control of plural data storing control parts simultaneously by constituting one pair of one magnetic disk device for saving data for one original and copy data storing part. CONSTITUTION:A data storing control part 1 saves data in an original data storing part 3 to a magnetic disk device 6 through a magnetic disk control part 8 with use of signal lines 5 and (b). Then a data storing control part 2 saves data in a copy data storing part 4 to a magnetic disk device 7 through the magnetic disk control part 8 with use of the signals 5 and (b).

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ファイルサブシステムに関する。[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to a file subsystem.

〔従来の技術〕[Conventional technology]

従来ファイルサブシステムは、データ内容の違う正デー
タ記憶部と副データ記憶部を同一の磁気ディスク装置に

タ記憶部のデータ内容を磁気ディスク装置にデータ退避

装置は使用出来ない為、副データ記憶部のデータ退避は
正データ退避が終了するのを待って行っていた。Conventional file subsystems allocate the primary data storage section and the secondary data storage section with different data contents to the same magnetic disk device, so one data storage control section transfers the data contents of the primary data storage section to the magnetic disk device. Since another data storage control unit cannot use the magnetic disk device while data is being saved in the secondary data storage unit, data in the secondary data storage unit is waited until the primary data saving is completed.

。The conventional file subsystem data evacuation method described above cannot perform data evacuation operations simultaneously on the primary or secondary data storage sections allocated to the same magnetic disk. There is a disadvantage that the data evacuation operation time becomes long and that while data is being evacuation from one data storage section, data cannot be evacuation even though the other data storage section is in a state where data evacuation is possible.

ある。The present invention provides a primary and secondary data storage section that is constituted by a plurality of IC memories that are volatile storage elements and has the same data content, a control section that controls the primary and secondary data storage section, and a data storage section that saves the data contents of the primary and secondary data storage section. In a file subsystem consisting of a magnetic disk device for data backup and a magnetic disk control unit that controls the magnetic disk device, one magnetic disk device for data backup is provided for each of the data storage unit and the sub data storage unit. By allocating one unit at a time, the data saving operations of all data storage units under a plurality of data storage control units can be performed simultaneously and in parallel.
