This system administration feature is new in the Solaris 10 6/06 release.
Starting with this release, the Solaris OS includes a set of predictive self-healing features to automatically capture, diagnose, and respond to hardware errors detected on your system.
The Solaris Fault Manager now provides support for CPU and Memory errors detected on x64 systems, including:
AMD Athlon 64 and OpteronTM CPU errors
Northbridge and Hypertransport links errors
DRAM correctable, uncorrectable, and ChipKill errors
The Solaris Fault Manager automatically diagnoses failures in x64 hardware. The Solaris Fault Manager also attempts to automatically offline or isolate a faulty CPU, cache, or DRAM memory region. Diagnostic messages are reported by the fmd daemon.
