1.6 Using the Solaris Predictive Self-Healing Feature
The Solaris Predictive Self-Healing (PSH) technology enables the server to diagnose problems
while the Solaris OS is running, and mitigate many problems before they negatively affect
operations.
The Solaris OS uses the fault manager daemon,
fmd(1M)
, which starts at boot time and runs in
the background to monitor the system. If a component generates an error, the daemon handles
the error by correlating the error with data from previous errors and other related information
to diagnose the problem. Once diagnosed, the fault manager daemon assigns the problem a
Universal Unique Identifier (UUID) that distinguishes the problem across any set of systems.
When possible, the fault manager daemon initiates steps to self-heal the failed component and
take the component offline. The daemon also logs the fault to the
syslogd
daemon and provides
a fault notification with a message ID (MSGID). You can use the message ID to get additional
information about the problem from Sun's knowledge article database.
The Predictive Self-Healing technology covers the following server components:
