Agentless and/or pre-boot support, and field replaceable unit (FRU) isolation
Systems and methods for providing agentless and/or pre-boot technical support, and Field Replaceable Unit (FRU) isolation. In some embodiments, an Information Handling System (IHS) includes an embedded controller (EC) distinct from any processor or Basic I/O System (BIOS), the EC having program instructions stored thereon that, upon execution, cause the IHS to: implement a network stack independently of an operational status of the processor or BIOS, perform one or more diagnostic operations upon the IHS, and communicate a result of the one or more diagnostic operations to a remote server using the network stack.
1. An Information Handling System (IHS), comprising:
an embedded controller (EC) distinct from any processor or Basic I/O System (BIOS), the EC having program instructions stored thereon that, upon execution, cause the IHS to:
implement a network stack independently of an operational status of the processor or BIOS;
perform one or more diagnostic operations upon the IHS; and
communicate a result of the one or more diagnostic operations to a remote server using the network stack, wherein the one or more diagnostic operations are configured to identify, prior to booting any Operating System (OS), a Field Replaceable Unit (FRU) to be replaced prior to a failure of the FRU.
2. The IHS of claim 1 , wherein program instructions are configured to be executed in the absence of any OS environment.
3. The IHS of claim 1 , wherein program instructions are configured to be executed in the absence of any graphical interface.
4. The IHS of claim 1 , wherein program instructions are configured to be executed in the absence of any user instruction.
5. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to host a web service via the EC using the network stack, and wherein the web service is configured to provide the result of the one or more diagnostic operations in response to a request.
6. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to send an alert to a pre-registered Internet Protocol (IP) address via the EC using the network stack, and wherein the alert includes an indication of the result of the one or more diagnostic operations.
7. The IHS of claim 1 , wherein the one or more diagnostic operations are configured to identify a processor failure or a BIOS failure.
8. The IHS of claim 1 , wherein the one or more diagnostic operations are configured to identify a power failure, a clock failure, or a code fetching failure.
9. The IHS of claim 1 , wherein to perform the one or more diagnostic operations, the program instructions, upon execution, further cause the IHS to:
inspect a voltage value for each of a plurality of platform-specific nodes;
compare a currently inspected voltage value with a previously inspected voltage value for each of the plurality of nodes; and
identify the FRU based upon the comparison.
10. A computer-implemented method, comprising:
implementing a network stack by an embedded controller (EC) independently of an operational status of a processor or Basic I/O System (BIOS);
performing, by the EC, one or more diagnostic operations upon the IHS; and
communicating a result of the one or more diagnostic operations, by the EC, to a remote server using the network stack, wherein the one or more diagnostic operations are configured to identify a Field Replaceable Unit (FRU) in a pre-boot environment and prior to a failure of the FRU.
11. The computer-implemented method of claim 10 , wherein the method is executed in the absence of any user interface.
12. The computer-implemented method of claim 10 , further comprising automatically sending an alert to a pre-registered Internet Protocol (IP) address by the EC using the network stack.
13. The computer-implemented method of claim 10 , wherein the one or more diagnostic operations are configured to identify a clock failure.
14. The computer-implemented method of claim 10 , wherein the one or more diagnostic operations are configured perform the identification of the FRU, at least in part, by inspecting a voltage value for each of a plurality of platform-specific nodes, and comparing a current voltage value with a previous value for each node.
15. A non-transitory, hardware storage device having program instructions stored thereon that, upon execution by an Information Handling System (IHS), cause the IHS to:
implement a network stack by an embedded controller (EC) independently of an operational status of a processor or Basic I/O System (BIOS);
perform, by the EC, one or more diagnostic operations upon the IHS; and
communicate a result of the one or more diagnostic operations, by the EC, to a remote server using the network stack, wherein the one or more diagnostic operations are configured to identify a Field Replaceable Unit (FRU) in a pre-boot environment and prior to a failure of the FRU.
16. The non-transitory hardware storage device of claim 15 , wherein program instructions are configured to be executed in the absence of any user interface.
17. The non-transitory hardware storage device of claim 15 , wherein program instructions are configured to cause the IHS to automatically send an alert to a pre-registered Internet Protocol (IP) address by the EC using the network stack.
18. The non-transitory hardware storage device of claim 15 , wherein the one or more diagnostic operations are configured to identify a power failure, a clock failure, or a code fetching failure.
19. The non-transitory hardware storage device of claim 15 , wherein the one or more diagnostic operations are configured perform the identification of the FRU, at least in part, by inspecting a voltage value for each of a plurality of platform-specific nodes, and comparing a current voltage value with a previous value for each node.
