3-4 SPARC Enterprise M4000/M5000 Servers Overview Guide • December 2010

Because operation failures and unauthorized accesses during system operation are

logged, the system administrator can immediately use the logs to investigate the

causes of unauthorized accesses.

3.2.3 System Status Management

System status management functions of the XSCF firmware include:

■ Managing any faults in resources such as CPUs, memory, and I/O systems while

the operating system is running

■ Managing errors and faults in fans and power supply units

System configuration information, which is used by the XSCF firmware, does the

following:

■ Reports errors and failures

■ Predicts midrange server problems

■ Provides users with prompt and accurate information whenever a problem occurs

Information on system operation and errors is stored as log data on the XSCF

firmware. It is used to analyze system problems. The system administrator, domain

administrator, and maintenance engineer can access the log data.

The XSCF firmware promptly collects hardware error and fault information and

stores it in XSCF. For information on the error messages displayed and their

explanations, refer to the SPARC Enterprise M3000/M4000/M5000/M8000/M9000

Servers XSCF User’s Guide.

3.2.3.1 Error Detection and Management

The XSCF firmware monitors the status of the main unit continuously to help the

system operate in a stable manner. The XSCF error detection and management

function does the following:

■ Promptly collects a hardware log when any system fault is detected

■ Analyzes the error

■ Determines the error location

According to the fault conditions, the XSCF firmware implements part of domain

degradation or resets the system when necessary. Easy-to-understand and accurate

information on hardware errors and fault locations is provided, which enables the

administrator to take prompt action.
