Details

Type

: Hardware Fault; memory.block.mirror.ue

Severity

: Critical

Description

: Fault due to a data compare error when memory is in mirror mode, detected by the CPU chip hardware.

Automated Response

: No immediate action is taken by XSCF. It is expected that the domain will take appropriate action.

Impact

: The DIMMs forming the mirroring pair where the compare error is detected are deconfigured (8 DIMMs total) after the domain using the affected memory reboots. The domain will get a memory uncorrectable error (UE) trap.

Indicted Hardware

: For M10-4/4S systems, the CMUU or CMUL is marked for replacement. For M10-1 systems, the MBU is marked for replacement.

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.
