Abstract

An information handling system includes a management switch and a plurality of management controllers coupled to the management switch to form a management network. A first management controller of the plurality of management controllers receives from the management switch a first list of active ports, wherein each particular active port includes an associated second management controller of the plurality of management controllers that is coupled to the particular active port. The first management controller further receives from the management switch, a plurality of second lists, one for each particular active port in the first list, each second list including an identification for the associated second management controller, and determines a map of the management network based upon the first list and the plurality of second lists.

Claims

1. An information handling system comprising:

a management switch device; and

a plurality of management controller device coupled to the management switch devices to form a management network;

wherein a first management controller device of the plurality of management controller devices;

receives from the management switch device a first list of active ports, wherein each particular active port is coupled to an associated second management controller device of the plurality of management controller devices;

receives from the management switch device a plurality of second lists, one for each particular active port in the first list, each second list including an identification for the associated second management controller device;

determines a map of the management network based upon the first list and the plurality of second lists; and

controls operation of the plurality of management controller device based upon the map and wherein a second management controller device of the plurality of management controller devices;

determines that the first management controller devices has failed; and

controls operation of the plurality of management controller device based upon the map in response to determining that the first management controller device has failed.

2. The information handling system of claim 1, wherein further the first management controller device:

mirrors first information for the first management controller device to third management controller device of the plurality of management controller devices based upon the map of the management network.

3. The information handling system of claim 2, wherein the first information

comprises a configuration setting for a processing system associated with the first management controller device.

4. The information handling system of claim 3, wherein the configuration setting comprises at least one of a sensor address for the processing system, a control address for the processing system, and a control threshold for the processing system.

5. The information handling system of claim 2, wherein the first information

comprises a back-up of operating code associated with the first management controller device.

6. The information handling system of claim 2, wherein the first information comprises sensor data history for the processing system.

7. The information handling system of claim 2, wherein further the first management controller device:

receives mirrored second information from each of the third management controller devices based upon the map of the management network; and

stores the mirrored second information.

8. The information handling system or claim 1, wherein further the first management controller device:

includes a rank among the plurality of management controller device;

receives a signal to power on a processing system associated with the first management controller device; and

powers on the processing system after a delay in response to receiving the signal, the delay being based upon the rank.

9. A method comprising:

receiving, at a first management controller of a plurality of management controllers, a first list of active ports from a management switch that is coupled to the first management controller, wherein each particular active port includes is coupled to an associated second management controller of the plurality of management controllers, wherein each management controller is included in one of a plurality of devices that are managed by the management network;

receiving, from the management switch, a plurality of second lists, one for each particular active port in the first list, each second list including an identification for the associated second management controller;

determining, at the first management controller, a map of the management network based upon the first list and the plurality of second lists;

determining, by the first management controller, that a particular one of the second management controllers has failed;

retrieving the mirrored second data associated with the particular second management controller; and

restoring the particular second management controller with the associated mirrored second data.

10. The method of claim 9, further comprising:

mirroring, at the first management controller, first information for the first management controller to the second management controllers based upon the map of the management network.

11. The method of claim 10, wherein the first information comprises a configuration setting for a processing system associated with the first management controller.

12. The method of claim 11, wherein the configuration setting comprises at least one of a sensor address for the processing system, a control address for the processing system, and a control threshold for the processing system.

13. The method of claim 10, wherein the first information comprises a back-up of operating code associated with the first management controller.

14. The method of claim 10, wherein the first information comprises sensor data history for the processing system.

15. The method of claim 10, further comprising:

receiving, at the first management controller, mirrored second information from each of the second management controllers based upon the map of the management network; and

storing, at the first management controller, the mirrored second information.

16. The method or claim 9, wherein:

the first management controller includes a rank among the plurality of management controllers; and

the method further comprises;

receiving a signal to power on a processing system associated with the first management controller; and

powering on the processing system after a delay in response to receiving the signal, the delay being based upon the rank.

17. A non-transitory computer-readable medium including code for performing a method, the method comprising:

receiving, at a first management controller of a plurality of management controllers, a first list of active ports from a management switch that is coupled to the first management controller, wherein each particular active port is coupled to an associated second management controller of the plurality of management controllers, wherein each management controller is included in one of a plurality of devices that are managed by the management network;

receiving, from the management switch, a plurality of second lists, one for each particular active port in the first list, each second list including an identification for the associated second management controller;

determining, at the first management controller, a map of the management network based upon the first list and the plurality of second lists;

determining, by the first management controller, that a particular one of the second management controllers has failed;

retrieving the mirrored second data associated with the particular second management controller; and

restoring the particular second management controller with the associated mirrored second data.

18. The computer-readable medium of claim 17, the method further comprising:

mirroring, at the first management controller, first information for the first management controller to the second management controllers based upon the map of the management network.
