Abstract: A disclosed method for managing a multi-node, HCI cluster provisions a central manager of the HCI cluster with an event listening service. The service is then registered with an agent in each HCI node. The service, when triggered by a management network configuration event, causes the agent to modify a management network configuration of the node in accordance with the event. Disclosed methods may respond to successfully applying a management network configuration change by sending a success notification to the central manager and awaiting a confirmation from the central manager. If confirmation is not received within a timeout interval, a timeout occurs and the management network configuration is rolled back to a last known good configuration. If the configuration change cannot be successfully applied, a failure notification is sent to the central manager and the configuration of the node is rolled back to a last known good configuration.
