摘要： In a storage system, one or more storage apparatuses provide a management computer with a first volume for storing data from the management computer, provide a host computer with a second volume for storing data from the host computer, and manage a volume address for the one or more storage apparatuses to manage the first volume and the second volume in the one or more storage apparatuses. The management computer issues a command specifying an arbitrary volume address to the one or more storage apparatuses, and designates, when receiving a normal response from the arbitrary volume address, a volume with the arbitrary volume address as the second volume.

摘要： A controller sets a specified time which is a time that specifies a time in the future relative to the current time for all of one or more secondary storage systems. The respective secondary storage systems have a logical volume for backup (BVOL), and set a backup preparation end state when a journal up to a specified time has been established, and report information showing a preparation end state to the controller. The controller issues a backup command to all of the one or more secondary storage systems when information showing a preparation end state is reported from all of the one or more secondary storage systems.

摘要： A computer system including a first storage system connected to a first host computer, a second storage system connected to a second host computer and a third storage system connected to the first and second storage systems. The second storage system sets transfer setting before an occurrence of a failure, the transfer setting being provided with a dedicated storage area to be used for transferring data to the third storage system by asynchronous copy in response to a failure at the first host computer. Before the start of data transfer between the second storage system and third storage system to be executed after an occurrence of the failure, the second storage system checks the dedicated storage area, data transfer line and transfer setting information, and if an abnormal state is detected, this abnormal state is reported to the host computer as information attached to the transfer setting.
