Type

Hardware Fault

   ioc.fe

Severity

Critical

Description

Fault due to a fatal error within an IOC, detected by the IOC itself. The fault affects the entire IOC.

Automated Response

For M12-2S systems, the physical partition using the IOC (both IO Channels) is reset. For M12-1 and M12-2 systems, the entire platform is reset.

Impact

The IOC (root complex in a CPU chip) is deconfigured.

Indicted Hardware

For M12-1 systems, the MBU is marked for replacement.

For M12-2/M12-2S systems, the CMUU or CMUL, where a CPU chip contains affected IOC, is marked for replacement.

For M12-2/M12-2S system with 2 CPU chip in a box, configuration of PCIe fabric will be changed triggered by IOC deconfiguration. This takes place when ioreconfigure is set to true with the setpparmode command.

Configuration of PCIe fabric is changed to maintain access to all the onboard devices and PCIe slots when either CMUU or CMUL is deconfigured.

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.
