摘要： A first server including a local disk and a second server are logically partitioned by virtualization units. The first and second servers each have a storage controller LPAR with a local disk sharing function running thereon. The storage controller LPARs running on the first and second servers communicate with each other. When a disk I/O command issued by the second LPAR running on the second server is transferred to the local disk of the first server, the second LPAR reads data stored in the local disk or writes data thereto. In this way, the local disk is shared.
