Patent ID: 7843811

Claim:
A method for a shut down process in a cluster system comprising a first node and at least one second node, said nodes connected to a communication network and an administrative network, and each node having an assigned name and an assigned host weight, the method being implemented in at least one of the first node and the at least one second node, the method comprising the steps of: a) inspecting a communication link via the communication network between the first and the at least one second node; b) determining, by the first node, which of the at least one second node is to be shut down after a failure of the communication link via the communication network between the first and the at least one second node; c) creating a demand report, by the first node, for the at least one second node determined to be shut down; d) sending the demand report to at least one node of the cluster system comprising the first and the at least one second node; e) calculating a delay time depending at least on the weight of the first node; and f) sending a shut down command, by the first node, over the administrative network to the at least one second node to be shut down after the expiry of the calculated delay time.
