You can run racadm help on each
attribute to show the available options.
For example:
/home/root# racadm help
system.thermalsettings.airexhau
sttemp
AirExhaustTemp—Specifies the Average
Air Exhaust Temperature
Usage: 0- 40; 1- 45; 2- 50; 3- 55; 4- 60; 5-
65; 255- 70; Default 255
Dependency -- Feature must be supported
to set the value.
To check existing setting on the system:
racadm get
system.thermalsettings.AirExhau
stTemp
It reports: AirExhaustTemp=70
This means that system is set to limit air
exhaust temperature to 70°C.
To set exhaust temperature limit to 60°C:
racadm set
system.thermalsettings.AirExhau
stTemp 4
The result is: “Object value modified
successfully,“ and a 60°C exhaust limit is
set.
If a certain AirExhaust Temperature limit
(such as 40°C) is not supported by the
platform, then running the command:
racadm set
system.thermalsettings.AirExhau
stTemp 0
results in error:
ERROR: RAC947: Invalid object value
specified.
Ensure that you specify the value
depending on the type of object.
For more information, see RACADM help.
To set the limit to default value:
racadm set
system.thermalsettings.AirExhau
stTemp 255
