Using a Configuration File for Sensor Information
On the Netra CP2500, you can enable or disable sensors, and configure sensor
threshold actions, such as shutdown and reboot, by editing the
/etc/picl/config/envmond.conf file.
Sample entries in the envmond.conf file are:
#entry format: name=value option
envmon-enable = true
sensor=CP2500-CPU-sensor threshold_shutdown_cmd="usr/sbin/shutdown -i5 -y -g15&"
/* presence of this line shows that the corresponding sensor is enabled */
Solaris Driver Interface
The PICL envmond plug-in opens a SMC driver stream and requests sensor events.
The SMC monitors the sensors and generates an event when it detects a change at a
particular sensor which meets one of the specified thresholds and generates an event
to local Solaris software. This event is captured by the SMC driver (as an IPMI
message) and is sent on an open STREAM that has requested sensor events. The
sensor events are received by the PICL plug-in. The PICL plug-in updates the State
property based on the information it extracts from the IPMI message and posts a
PICL event.
