摘要：
A data sharing method and system between information processing systems which enable an information processing system to share data in an internal disk unit possessed by another information processing system. A disk control unit within the other information processing system having an external disk unit or an external disk unit includes a disk data sharing mechanism for creating a read/write request to the internal or external disk unit from a command equivalent to a read/write request to a data in a conventional disk subsystem. This mechanism emulates a CCW command to access data in the disk unit.
