computer readable program code for causing the KVM switch to automatically generate a graphical user interface including the identity of the identified compute node for display on a display device that is connected to the KVM switch.
2. The computer program product of claim 1 , wherein the one or more predetermined problems is selected from an inability to communicate over the network, an operating system error, and a service processor error.
3. The computer program product of claim 1 , further comprising:
computer readable program code causing the keyboard, video and mouse switch to automatically switch to connect the display device to the identified compute node.
4. The computer program product of claim 3 , further comprising:
computer readable program code for requiring users to log into a user account before gaining access to use the keyboard, video and mouse switch; and
computer readable program code for causing the keyboard, video and mouse switch to automatically switch to connect the display device to the identified compute node is only available to a user account that has been assigned automatic switching privileges.
5. The computer program product of claim 1 , wherein the keyboard, video and mouse switch uses intelligent platform management interface (IPMI) commands to communicate with the service processors of the plurality of compute nodes.
6. The computer program product of claim 1 , further comprising:
computer readable program code for distinguishing the manner in which the identified compute node is displayed on the graphical user interface, wherein the identified compute node is displayed along with the plurality of the compute nodes.
7. The computer program product of claim 6 , wherein distinguishing the manner in which the identified compute node is displayed on the graphical user interface is a visual effect selected from highlighting background, outlining, font change, color change, blinking, shaking, scrolling and combinations thereof.
8. The computer program product of claim 1 , further comprising:
computer readable program code for filtering a list of the plurality of compute nodes to display only those compute nodes from among the plurality of compute nodes that are experiencing one or more of the predetermined problems.
9. The computer program product of claim 1 , further comprising:
computer readable program code for reordering a list of the plurality of compute nodes to display those compute nodes from among the plurality of compute nodes that are experiencing one or more of the predetermined problems at the top of the list.
10. The computer program product of claim 1 , further comprising:
computer readable program code for displaying the error message along with the identity of the identified compute node on the graphical user interface.
11. A computer program product including computer readable program code embodied on a non-transitory computer readable storage medium, the computer program product including:
computer readable program code for causing a keyboard, video and mouse (KVM) switch to communicate over a network with service processors of a plurality of compute nodes, wherein the keyboard video and mouse switch polls the service processor of each of the plurality of compute nodes;
computer readable program code for causing the KVM switch to identify a compute node from among the plurality of compute nodes that is unreachable over the network; and
computer readable program code for causing the keyboard, video and mouse switch to receive a signal from the identified compute node through a keyboard, video, or mouse input/output port of the identified compute node connected to the keyboard, video and mouse switch, wherein the signal identifies one or more predetermined problems experienced by the identified compute node; and
computer readable program code for causing the KVM switch to automatically generate a graphical user interface including the identity of the identified compute node for display on a display device that is connected to the KVM switch.
12. The computer program product of claim 11 , wherein the signal is a predetermined sequence or combination of keyboard, mouse or video signals.
13. The computer program product of claim 11 , further comprising:
computer readable program code for distinguishing the manner in which the identified compute node is displayed on the graphical user interface, wherein the identified compute node is displayed along with the plurality of the compute nodes.
14. The computer program product of claim 13 , wherein distinguishing the manner in which the identified compute node is displayed on the graphical user interface is a visual effect selected from highlighting background, outlining, font change, color change, blinking, shaking, scrolling and combinations thereof.
15. The computer program product of claim 11 , further comprising:
computer readable program code for filtering a list of the plurality of compute nodes to display only those compute nodes from among the plurality of compute nodes that are experiencing one or more of the predetermined problems.
16. The computer program product of claim 11 , further comprising:
computer readable program code for reordering a list of the plurality of compute nodes to display those compute nodes from among the plurality of compute nodes that are experiencing one or more of the predetermined problems at the top of the list.
17. The computer program product of claim 11 , further comprising:
computer readable program code for displaying the error message along with the identity of the identified compute node on the graphical user interface.
