Automated cluster node configuration

Embodiments of the present invention address deficiencies of the art in respect to cluster node configuration and provide a novel and non-obvious method, system and computer program product for automated cluster node configuration. In one embodiment of the invention, an automated cluster node configuration method can be provided. The method can include assigning an initial IP address to a newly added cluster node in a cluster, identifying a hardware address for the newly added cluster node, locating an association with the hardware address in a switch in the cluster, re-configuring the assignment of the IP address based upon the located association in the switch, and requesting a reboot of the newly added cluster node with the re-configured assignment of the IP address.
