FIGURE 5-1
Auto Diagnosis and Recovery Process
The following summary describes the process shown in
FIGURE 5-1
:
1. The SC detects hardware error and pauses the operating system.
2. The AD engine analyzes the hardware error and determines which field-
replaceable units (FRUs) are associated with the hardware error.
3. The AD engine provides one of the following diagnosis results, depending on the
hardware error and the components involved:
■
Identifies a single FRU that is responsible for the error.
■
Identifies multiple FRUs that are responsible for the error. Be aware that not all
components listed may be faulty. The hardware error could be related to a
smaller subset of the components identified.
■
Indicates that the FRUs responsible for the error cannot be determined. This
condition is considered to be “unresolved” and requires further analysis by
your service provider.
4. The AD engine records the diagnosis information for the affected components
and maintains this information as part of the component health status (CHS).
5. The AD reports diagnosis information through console event messages.
