Patent number: 7117314Abstract: In a computer system including a disk subsystem having channel interface compatible to a count-key-data format and a SCSI interface compatible to a fixed length data format, the disk subsystem is connected to a CPU controlled by an open system operating system through the SCSI interface, and connected to an other CPU controlled by a main frame operating system through the channel interface. The CPU is provided with a CKD record access library and a VSAM access library which accesses in a FBA format the VSAM record stored by the other CPU in a CKD format in the disk subsystem and allows the access by an application program of the CPU as a VSAM record based on VSAM control information.Type: GrantFiled: April 13, 2004Date of Patent: October 3, 2006Assignee: Hitachi, Ltd.Inventors: Motohiro Kanda, Akira Yamamoto, Toshio Nakano, Minoru Yoshida

Patent number: 6735676Abstract: A first computer having a first interface connected to a backup storage device, and a second computer having a second interface differing in format from the first interface share a common storage device which can be connected to either the first interface or the second interface. The first and second computers are connected to the shared storage device via a storage device controller. In response to a data access command issued to the shared storage device by either the first computer or the second computer, the storage device controller converts a data address specified by the data access command to a data address used within the shared storage device. By using the data address obtained by the conversion, the shared storage device is accessed. The first computer creates, in the backup storage device, a backup of data stored in the shared storage device via the storage device controller.Type: GrantFiled: July 21, 2000Date of Patent: May 11, 2004Assignee: Hitachi, Ltd.Inventors: Motohiro Kanda, Akira Yamamoto, Akinobu Shimada
