A method for use in a distributed processing system having a plurality of nodes wherein selected nodes are fenced or unfenced from selected ones of peripheral device server nodes in a fence/unfence operation. A common memory is provided for storing a fence map listing nodes fenced from server nodes. In the fence/unfence operation, a request processing node proposes changes to the fence map, and if no node fails during the fence/unfence operation, the proposed changes are changed into committed changes. If a node fails during the fence/unfence operation, the proposed changes are erased, the previous committed changes are restored, and the fence/unfence request is removed from the process queue for processing by the request processing node.
