ABSTRACT:
Access of a malfunctioning server to a data storage facility is blocked. Characteristics such as IAmAlive signals from a server are monitored and when out of profile a malfunction is indicated and data access of that server is inhibited. Characteristics continue to be monitored for a return from the malfunction. The system can be used in a resilient cluster of servers to shut out a malfunctioning server and enable its recovery to be indicated so as to enable readmittance to the cluster.
