Chapter 2 Environmental Monitoring 35
The environmental monitoring parameter values in the application program apply
when the system is running at the Solaris level and do not necessarily have to be the
same as the default settings programmed by the SMC and used by the OpenBoot
PROM. The OpenBoot PROM environmental monitoring only applies when the
system is running at the OpenBoot PROM level.
Reading Temperature Sensor States Using the
PICL API
Temperature sensor states may be read using the libpicl API. The following
properties are supported in a PICL temperature sensor class node:
The PICL plug-in receives these sensor events and updates the State property based
on the information extracted from the IPMI message. It then posts a PICL event.
Threshold levels of the PICL node class temperature sensor are:
■ Warning
■ Shutdown
■ Power Off
To obtain a reading of temperature sensor states, use the prtpicl -v command:
Sample PICL output of temperature sensors on a Netra CT system is as follows.
