Storage system group including scale-out storage system and management method therefor

摘要

A management system is coupled to a storage system group including a scale-out storage system (a virtual storage system). The management system has storage management information, which includes information denoting, for each storage system, whether or not a storage system is a component of a virtual storage system. The management system, based on the storage management information, determines whether or not a first storage system is a component of a virtual storage system, and in a case where the result of this determination is affirmative, identifies, based on the storage management information, a second storage system, which is a storage system other than the virtual storage system that includes the first storage system, and allows a user to perform a specific operation only with respect to this second storage system.

主权项

1. A management system coupled to a plurality of storage systems including a plurality of logical volumes, comprising:
a processor; and a memory storing instructions, which are executable by the processor, and management information which includes an identifier of a consistency group, an identifier of the storage systems and an identifier of the logical volumes, wherein the consistency group is a group of the logical volumes which maintain compatibility of data with each other, and wherein the processor is configured to:
receive a request for a remote copy including an identifier of a logical volume of a source of the remote copy and an identifier of a logical volume of a destination of the remote copy;identify the consistency group corresponding to the logical volume of the source of the remote copy and the consistency group corresponding to the logical volume of the destination of the remote copy by referring to the management information; andcopy data from the logical volume of the source of the remote copy to the logical volume of the destination of the remote copy and set a remote copy pair between the logical volume of the source of the remote copy and the logical volume of the destination of the remote copy, if the consistency group of the logical volume of the source of the remote copy is not equal to the consistency group of the logical volume of the destination of the remote copy.
