Summary: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. L'invention concerne un procédé et un système d'arbitrage de la propriété d'une ressource quorum logique, telle qu'un volume de quorum logique, comprenant une ou plusieurs ressources quorum physiques, de sorte qu'un réseau de stockage présentant plusieurs dispositifs de stockage soit formé. Les responsabilités de gestion d'arbitrage et de volume sont nettement réparties entre un logiciel de gestion de grappes et un logiciel de gestion de volume. Le logiciel de gestion de grappes gère le processus d'arbitrage sans connaître les détails relatifs à la manière dont la ressource quorum logique est formée. Le logiciel de gestion de volume gère la formation et la gestion du volume du quorum logique sans avoir de détails sur le processus d'arbitrage.
