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 /* Globally enables/disables PICL-based environmental monitoring */

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.
