Abstract
The invention provides a method and system for arbitrating for ownership of a logical quorum resource, such as a logical quorum volume, comprising one or more physical quorum resources so as to form a storage network having a plurality of storage devices. Arbitration and volume management responsibilities are cleanly divided between cluster management software and volume management software. The cluster management software handles the arbitration process without knowing the details of how the logical quorum resource is formed. The volume management software handles the formation and management of the logical quorum volume without having details of the arbitration process.
