Sun Fire 6800/4810/4800/3800 Auto Diagnosis and Recovery Features
Version 5.15.0 of the system controller (SC) firmware introduces several new features to improve the availability, serviceability, diagnosability, and repair characteristics of Sun Fire 6800/4810/4800/3800 systems. The new features are:
Auto diagnosisAutomated diagnosis of run time hardware faults
Component health statusPersistent record of the information stored in the component
Auto restorationAutomatic restoration of the domain with the fault isolated
Domain hang recoveryDetect and recover from a domain hang
Repeated domain panic recoveryRun power on-self test (POST) at increasing diagnosis levels to identify and isolate the faulty hardware (if any)
Additionally, some enhancements have been made in the Solaris Operating Environment (Solaris OE) to improve the availability of the domain. These enhancements are:
Virtual memory page retirementRetire memory pages that have an increased probability of experiencing fatal errors
CPU offliningOff-line a CPU when an L2_SRAM module has an increased probability of experiencing fatal errors
This article describes the Sun Fire 6800/4810/4800/3800 system availability enhancements provided in the system controller (SC) firmware version 5.15.0 release and Solaris 8 Operating Environment (Solaris OE) kernel updates. Basic knowledge of the Sun Fire 6800/4810/4800/3800 system is required.
