x86: Sun Fire X4500 SATA Disk FMA

A new Fault Management Architecture-based diagnosis engine (DE) is provided on the Sun Fire X4500. This DE monitors the disk drives for predictive failures by using the SMART technology in the disk drive's own firmware. When a disk failure is imminent, the LED next to the disk is illuminated and a Fault Management Architecture fault is generated. This fault alerts the administrator to take specific action to ensure system availability and full performance.
