Details

Type

Hardware Fault

   ioc.ch.fe

Severity

Major

Description

Fault due to a fatal error within an IOC, which is related to an IO Channel.

Automated Response

The domain using the IO Channel (IOC) 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.

If the fault was detected while running POST, such event is listed in the following categories:

-fe-reg-cmp-err 02002400, 02002421, 02002423, 02002424, 02002425, 02002432 The expected result is not obtained by reading an IO channel register;
-fe-dma-test-err 02002426, 02002427, 02002438 DMA test faced uncorrectable error.
-fe-msi-test-err 02002428, 02002429, 0200242a, 0200242b MSI test face unrecoverable error.

If it’s fe-dma-test-err or fe-msi-test-err, error is caused by data read by IOC. In such case, XSCF analyzes origin of wrong data and shows it as suspect.

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

Configuration of PCIe fabric is changed to maintain access to all the onboard devices and PCIe slots even 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.
