Sensor Device Record (SDR) Threshold Management
The SBC update tool can be use to manage the SDR thresholds setting of all sensors.
The SDR threshold change feature is for customers that want to change the default
values of Intel defined SDR thresholds. The primary use of this is to change upper non-
critical temperature thresholds so that the blade temperature thresholds can be set for
different temperature environments. The types of thresholds that can be managed are
follows:
The following subsections describe step-by-step procedure to read, change and restore
the SDR thresholds setting.
Changes to voltage and current thresholds can lead to device corruption or failure.
Intel is not responsible for customer changes of thresholds that fall outside the Intel-
defined factory default settings.
Reading Thresholds Using KCS Interface
To read the threshold from a device via KCS, specify the threshold mode using
threshold
The syntax of the command is:
# sbcupdate -I kcs -M threshold [--get-thr-factory]
where:
The following is an example to read the threshold of a sensor threshold:
# sbcupdate -I kcs -M threshold --get-thr-factory --get-thr-active
--get-thr-sdr --get-thr -s 0x93
The output from this command should be similar to the following:
