PSH Overview
The Oracle Solaris PSH technology enables the server module to diagnose problems
while the Oracle Solaris OS is running and to mitigate many problems before they
negatively affect operations.
The Oracle Solaris OS uses the fault manager daemon, fmd(1M), which starts at boot
time and runs in the background to monitor the server module. If a component
generates an error, the daemon correlates the error with data from previous errors
and other relevant information to diagnose the problem. Once diagnosed, the fault
manager daemon assigns a UUID to the error. This value distinguishes this error
across any set of server modules.
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 (sometimes
labeled MSG-ID). You can use the message ID to get additional information about the
problem from the knowledge article database.
The PSH technology covers the following server module components:
