   if.fe-cpu-cpu

Severity

Major

Description

Fault due to a fatal error on the interface between CPU chips.

Automated Response

The single PPAR using the CPU chip is reset.

Impact

The CPU chip is deconfigured. For M10-1, this means the platform will be unbootable.

Indicted Hardware

For M10-1 systems, the MBU is marked for replacement.

For M10-4/4S systems, the CMUU or CMUL where this CPU chip is mounted is marked for replacement. When the fault is detected between a CPU chip on CMUL and a CPU chip on CMUU, there is a chance that a connector between CMUL and CMUU has a problem.

For M10-4/4S system with 4 CPU chip in a box, configuration of PCIe fabric will be changed triggered by CPU chip deconfiguration. This takes place when ioreconfigure is set to true by setpparmode command.

Configuration of PCIe fabric is changed as follows:

- When CPU#0 on CMUL is deconfigured:
  Configuration of PCIe switch 0 is changed to allow access from CPU#0 on CMUU to the built-in SAS chip, USB chip and GbE i/f #0 and #1.
  Configuration of PCIe switch 1 is changed to allow access from CPU#0 on CMUU to the first PCIe slot.

- When CPU#1 on CMUL is deconfigured:
  Configuration of PCIe switch 2 is changed to allow access from CPU#1 on CMUU to the fourth and fifth PCIe slots.
  Configuration of PCIe switch 3 is changed to allow access from CPU#1 on CMUU to the eighth and ninth PCIe slot.

- When CPU#0 on CMUU is deconfigured:
  Configuration of PCIe switch 0 is changed to allow access from CPU#0 on CMUL to the built-in GbE i/f #2 and #3.
  Configuration of PCIe switch 1 is changed to allow access from CPU#0 on CMUL to the second and third PCIe slots.

- When CPU#1 on CMUU is deconfigured:
  Configuration of PCIe switch 2 is changed to allow access from CPU#1 on CMUL to the sixth and seventh PCIe slots.
  Configuration of PCIe switch 3 is changed to allow access from CPU#1 on CMUL to the tenth and eleventh PCIe slot.

Suggested Action for System Administrator

The recommended service action for this event is to schedule replacement of the affected component(s) at the earliest possible convenience. Although the hardware may be functioning, it is not intended nor recommended that the faulted component(s) remain in the system for a prolonged period of time.

Refer to the following document for the latest procedures for displaying event content in preparation for submitting a service request and applying any post-repair actions that may be required.
