About Fault Management

The fault management software of the Sun Blade 8000 Series monitors hardware health and diagnoses and reports hardware failures on system components. Fault management also monitors environmental conditions and reports when the system's environment is outside acceptable parameters. Various sensors on the system chassis, the power supplies (PSUs), Server Modules (blades), and fans are continuously monitored and, when a sensor registers a problem, the fault management software – which runs on the Chassis Monitoring Module (CMM) – is notified.

Fault management then diagnoses the problem. If it determines that a hardware or environmental failure has occurred, fault management lights the Service Action Required LED on the affected component. The ILOM management interfaces will also be updated to reflect the failure (the fault), and the failure is recorded as a fault in the event log.

Note

The Sun Blade 8000 Series's fault management software is entirely unrelated to Solaris's Fault Management Architecture (FMA). Fault management is part of the system's management software and does not interact with the blade hosts or their operating systems.
