STORAGE SYSTEM AND MANAGEMENT COMPUTER

摘要

A storage system according to the present invention includes multiple real storage subsystems, and defines a virtual storage subsystem composed of resources included in one or multiple real storage subsystems. Upon defining a virtual storage subsystem, a virtual logical partition corresponding to a real storage subsystem is provided in the virtual storage subsystem, and a logical partition correlation information which is attribute (limitation) information showing whether various resource management operations extending over virtual logical partitions can be executed or not to each pair within the multiple virtual logical partitions is created and managed. When a management operation instruction regarding the virtual storage subsystem is received, if the resources being the operation target based on the management operation instruction belong to multiple virtual logical partitions, whether resource operation can be executed or not is determined based on the logical partition correlation information, and management operation is limited thereby.

主权项

1. A storage system comprising multiple storage subsystems receiving access from a host computer, and a management computer managing the multiple storage subsystems; wherein
each of the multiple storage subsystems has one or more resources; the storage system is configured to define a virtual storage subsystem including at least a portion of the resource of a first storage subsystem within the multiple storage subsystems and at least a portion of the resource of a second storage subsystem within the multiple storage subsystems, and receive a management operation request designating the virtual storage subsystem or a resource belonging to the virtual storage subsystem; upon receiving the management operation request designating multiple resources belonging to the virtual storage subsystem and a resource operation content, if the multiple resources are included in the same storage subsystem, the management computer transmits the management operation request to the said same storage subsystem; and if the multiple resources are included in different storage subsystems, the management computer determines whether the designated operation content can be executed or not, and if the designated resource operation content cannot be executed, notifies an operator that the designated resource operation content cannot be executed.
