Patent ID: 8341455

Claim:
A management method of managing a storage system, the storage system providing a plurality of logical volumes and being configured from one or more apparatuses, the storage system providing a plurality of host computers which are coupled to a port, the method comprising: storing cluster information in a memory; detecting, via a processor, a failover that has occurred in the plurality of host computers and updating the cluster information; receiving, via an input/output device, 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; (A) specifying, via the processor, by referencing the cluster information, 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) specifying, via the processor, 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 and application program identified by the application instance identifier for input use; (C) determining, via the processor, whether the inactive-state host computer is able to access the first storage subsystem and the first logical volume; (D) selecting, via the processor, in a case where the inactive-state host computer is not able to access the first logical volume, a second storage subsystem included in the storage system that is accessible from the inactive-state host computer, and sending 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, via the processor, 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, causing 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.
