Patent number: 7483928Abstract: A managing computer (manager) manages replication of data areas inside a storage or among storages. A storage volume management module of the manager manages policy of the volume and its properties. When replication of a volume is set, a volume of a replication destination appropriate for a volume of a replication source is generated using the policy and the properties to form a replication pair. A route management module of the manager and its volume management module bring the policy and the properties of the volumes, and the policies and conditions of lines into conformity with one another. When any fault occurs in a line route used for data transfer during replication of the volume, a separate line route is utilized, and a fault countermeasure is taken for replication of the volumes in accordance with the policy and properties of the volumes.Type: GrantFiled: January 3, 2007Date of Patent: January 27, 2009Assignee: Hitachi, Ltd.Inventors: Masayasu Asano, Kenichi Shimooka, Daisuke Shinohara

Patent number: 7206823Abstract: In a computer system having two or more kinds of storage networks, effective information is set by use of network identifiers. An identifier acquisition unit, and a router information acquisition unit, of a management computer acquire a network identifier of a port, and information about the port connection relationship, from a computer and a protocol-conversion-type router. An identifier analyzing unit creates an identifier path from each computer to a storage device. A setting judgment unit judges whether this identifier path is independent of, or shared by, identifier paths of the other computers. According to the judgment, instead of using a network identifier of the computer, a setting execution unit uses, for information settings, an identifier of a port on the low-order side of the protocol-conversion-type router or a logical identifier that is generated.Type: GrantFiled: June 30, 2004Date of Patent: April 17, 2007Assignee: Hitachi, Ltd.Inventors: Hiroshi Furukawa, Kenichi Shimooka
