Patent ID: 7865772

Claim:
A computer system management method in a computer system, the computer system comprising a server; a virtualization switch, which is connected to the server via a first path; a storage device, which is connected to the virtualization switch via a second path; and a management server, which is connected to the server, virtualization switch, and storage device via a network, wherein the management server comprises a configuration history information table, the method comprising; acquiring, by the management server, and recording in the configuration history information table, a history of the setting information of the computer system when the setting of the computer system is changed; when there is a recovery command for a prescribed time from the computer system, comparing, by the management server, from among the history information recorded in the configuration history information table, a first configuration information corresponding to the specified recovery time, and a second configuration information corresponding to the current time, and when the two do not coincide, sending, by the management server, the first configuration information to the device, from among the server, virtualization switch, and storage device, in which a setting change is required; changing, by the device, from among the server, virtualization switch, and storage device, which received the first configuration information, a setting based on this first configuration information, wherein the management server selects a recovery method of any of recovery methods, which physically and logically restore, or logically restore, or logically and partially restore a system configuration specified by the first configuration information, and wherein the management server compares the first configuration information and second configuration information, and when the setting of the first path and the second path coincide at the current time and at the recovery time, and path competition is generated, changes the setting of the second path at the current time, and thereafter, changes the setting of the first path at the current time.
