Details

Type

Hardware Fault

   cpu.core.ce

Severity

Minor

Description

Fault due to constant correctable errors detected by a SPARC64 XII CPU chip within one of its own cores. The fault is serious enough that the domain is asked to offline the core.

Automated Response

No immediate action is taken. The domain subscribes to this fault and the domain software will attempt to offline the core. The platform administrator should make some sort of arrangement to make sure the domain does not use the CPU chip for an extended period of time.

Impact

The core of the CPU chip is deconfigured the next time the domain reboots.

Indicted Hardware

For M12-1 systems, the Motherboard is marked for replacement. For M12-2 and M12-2S systems, the related Motherboard (CMUU or CMUL) is marked for replacement. If this is a UE in the (shared) L3$, then each of the cores is separately indicted (this is because the domain subscribes to this fault, and all cores must be offlined).

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.
