108 Sun Fire X4500/ X4540 Servers Administration Guide • October 2008
After processing sufficient telemetry to reach a conclusion, a diagnosis engine
produces another event called a fault event that is broadcast to any agents deployed
on the system that know how to respond. A software component known as the
Solaris Fault Manager,
fmd
(1M), manages the diagnosis engines and agents,
provides a simplified programming model for these clients as well as common
facilities such as event logging, and manages the multiplexing of events between
producers and consumers.
The Sun Fire X4540 Server has a Fault Management Application (FMA) that provides
fault monitoring and hotplug processing. The FMA provides passive fault
monitoring by analyzing each disk once per hour to determine if a disk fault is
imminent. If a disk fault is imminent, an FMA fault is generated and the amber Fault
LED for that disk is activated.
Sun Fire X4540 Fault Management
Utilities
The Sun Fire X4540 server FMA obtains diagnostic information from the fault
management utilities in Solaris. The fault management utilities described are:
■
“
fmd
Command” on page 109
■
“
fmdump
Command” on page 110
■
“
fmadm
Command” on page 112
■
“Displaying Fault Statistics Using the
fmstat
Command” on page 113
You can also refer to the man pages for
fmd
(1M),
fmadm
(1M),
fmdump
(1M), and
fmstat
(1M) for more information about the individual fault management utilities.
