Sun Microsystems CP2500 manual Reading Temperature Sensor States Using

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:

TABLE 2-4PICL Temperature Sensor Class Node Properties

Property	Type	Description
LowWarningThreshold	INT	Low threshold for warning
LowShutdownThreshold	INT	Low threshold for shutdown
LowPowerOffThreshold	INT	Low threshold for power off
HighWarningThreshold	INT	High threshold for warning
HighShutdownThreshold	INT	High threshold for shutdown
HighPowerOffThreshold	INT	High threshold for power off

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 -vcommand:

#prtpicl -c temperature-sensor -v

Sample PICL output of temperature sensors on a Netra CT system is as follows.

#prtpicl -c temperature-sensor -v
