| 4 | Description: Sensor groups directory for POWER9 powernv servers |
| 5 | |
| 6 | Each folder in this directory contains a sensor group |
| 7 | which are classified based on type of the sensor |
| 8 | like power, temperature, frequency, current, etc. They |

| 18 | Writing 1 to this file will clear the minimum and |
| 19 | maximum values of all the sensors in the group. |
| 20 | In POWER9, the min-max of a sensor is the historical minimum |
