How to get sensor threshold on BMC-based system with a specific sensor number

Applicable model list
All products with BMC functional
Description
This guide should also be helpful for user with sensor threshold problems to learn
how to get sensor threshold using IPMI.

# ipmitool raw 0x04 0x27 [sensor number]

Ex: sensor number = 0x19 => CPU-TMP

response : 18 00 00 00 5a 69 00  

Note: Byte1( Completion Code) does not show because the command success. Then, ignore Byte1.

Therefore, response value "18" represents Byte2 and "18" means 0001 1000 in Binary. That means "upper critical threshold" and " upper non-critical threshold" are set.

The response value "5a" and "69" correspond to Byte6 and  Byte7 respectively. The value "5a" of Byte6(upper non-critical threshold) is equal to 90 in decimal, which means the upper non-critical threshold of CPU-TMP is 90 degrees C. The value "69" of Byte7(upper critical threshold) is equal to 105 in decimal, which means the upper critical threshold of CPU-TMP is 105 degrees C.
