Abstract
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.
Claims15
An automated cluster node configuration method comprising:
- assigning an initial Internet protocol (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.
A cluster computing data processing system comprising:
- a plurality of cluster nodes in a cluster;
- a dynamic host configuration protocol (DHCP) server communicatively linked to the cluster and configured to dynamically assign Internet protocol (IP) addresses to requesting ones of the cluster nodes;
- a management server communicatively linked to the cluster;
- and,
- a node bringup service coupled to the management server, the node bringup service comprising program code enabled identifying a hardware address for a newly added one of the cluster nodes, to locate an association with the hardware address in a switch in the cluster, to re-configured the DHCP server in assigning an IP address to the newly added one of the cluster nodes based upon the located association in the switch, and to request a reboot of the newly added one of the cluster nodes with a re-configured assignment of the IP address.
A computer program product comprising a computer readable usable storage device embodying computer usable program code for automated cluster node configuration, the computer program product comprising:
- computer usable program code for assigning an initial Internet protocol (IP) address to a newly added cluster node in a cluster;
- computer usable program code for identifying a hardware address for the newly added cluster node;
- computer usable program code for locating an association with the hardware address in a switch in the cluster;
- computer usable program code for re-configuring the assignment of the IP address based upon the located association in the switch;
- and,
- computer usable program code for requesting a reboot of the newly added cluster node with the re-configured assignment of the IP address.
