Abstract
A storage control apparatus, in communication with a cluster of storage devices in a storage network having plural administrator systems, comprises a cluster lock requester component, a cluster lock receiver component and a configuration component, wherein, responsive to receipt of a cluster lock by said cluster lock receiver component, the configuration component is operable to configure a logical resource object within said cluster. The apparatus may also include a cluster lock granter component operable to grant a cluster lock to the cluster lock receiver component responsive to said cluster lock requester component. A method of operating a storage control apparatus includes method steps corresponding to functional components of an apparatus and may be embodied in computer program codes.
