Abstract:
1. A management system that manages a storage system which provides a plurality of logical volumes and which is configured from one or more apparatuses, and the storage system provides a plurality of host computers, the management system comprising: a port coupling to the plurality of host computers; a memory storing cluster information; a processor detecting a failover that has occurred in the plurality of host computers and for updating the cluster information; and an input/output device receiving a backup setting request including a virtual host identifier for input use, an application instance identifier for input use, and a backup schedule input value, wherein the processor: (A) by referencing the cluster information, specifies an active-state host computer corresponding to the virtual host identifier for input use, and an inactive-state host computer corresponding to the active-state host computer included in the plurality of host computers; (B) specifies a first storage subsystem included in the storage system, and a first logical volume provided by the first storage subsystem, which the active-state host computer accesses by executing an application program identified by the application instance identifier for input use; (C) determines whether the inactive-state host computer is able to access the first storage subsystem and the first logical volume; (D) in a case where the inactive-state host computer is not able to access the first logical volume, selects a second storage subsystem included in the storage system that is accessible from the inactive-state host computer, and sends to the first storage subsystem a replication establishment instruction for disaster recovery use, with the first logical volume being made a copy source, and a second logical volume provided by the second storage subsystem being made a copy destination; and (E) by sending to the active-state host computer, via the port, a backup schedule registration instruction including backup schedule instruction information created on the basis of the backup schedule input value, causes the active-state host computer to control a replication process, for backup use, with the first logical volume in accordance with the backup schedule input value being made the copy source, and with one or more third logical volumes included in the first storage subsystem being made copy destinations.
