Clearing Faults

Component Type	Fault Status
Customer-replaceable units (CRUs) that are hot-swappable and are monitored by the SP	Faults are cleared automatically when the failed component is replaced and the updated status is reported as deasserted.
CRUs and field-replaceable units (FRUs) that have a FRUID container with identity information	Faults are cleared automatically when the failed component is replaced.
CRUs and FRUs that are not hot-swappable or lack a FRUID container with identity information	Faults are not cleared automatically.

You can use the Oracle ILOM web interface or the command-line interface (CLI) to manually clear faults. For information about how to use the Oracle ILOM web interface or the CLI to clear server faults, see the Oracle ILOM 3.0 Documentation Collection.

The following types of faults are diagnosed by the SP.

Table 10 Types of Component Faults

Fault Type	Component or Component Status
Environmental events	Fan modules, power supplies, ambient temperature, and AC power loss
Memory Reference Code (MRC) errors and warnings	Memory initialization and population
I/O Hub (IOH) uncorrectable error events	Motherboard
Memory ECC uncorrectable and correctable events	Memory DIMMs
CPU uncorrectable error events	Processor
Boot progress events	Power-on, power-off, IPMI, MRC, QPI, BIOS, setup, and boot retries
Service Processor error events	Oracle ILOM

This table lists the server component faults that persist after a system cold boot and the action to clear the fault.

Table 11 Clearing Faults for Components

Component	Action to Clear
DDR3 Memory DIMMs	Automatically cleared when replaced
CPU module	Clear fault manually after component replacement
PCIe cards	Clear fault manually after component replacement
Fan module	Automatically cleared when the sensor status is OK
Power supply	Automatically cleared when the sensor status is OK
Disk drive	Automatically cleared when the sensor status is OK
