Abstract: A logically partitioned data processing system has a policy defining responsive actions to be undertaken by a process in one partition because of a monitored failure of an operating system in another partition. When such a failure occurs, the monitoring partition, if authorized, automatically communicates with a hypervisor to initiate the responsive actions on the failing partitions to reset and/or reconfigure that failing partition. Communication of action request between the partition and the hypervisor is accomplished without operator intervention, through a Service Call Logical Processor interface.
