Automatic switching method of a right of management/control for shared-storage unit |
摘要 |
An automatic method for switching a right of management/control for a shared-storage unit between a plurality of service processors in a cluster-coupled system having a shared-storage unit with a service processor selecting register and a plurality of clusters connected to the shared-storage unit, each clusters having a service processor, includes the steps of: registering a physical number of the service processor which acquires the right of management/control in the service processor selecting register; and providing a communication line connecting all service processor; wherein when a first cluster detects power-off or hang-up message from the cluster which includes the service processor registered in the service processor selecting register through the communication line, the first cluster determines a new physical number of the service processor which acquires the right of management/control based on a predetermined decision theory, and registers the determined physical number in the service processor selecting register.
