Setting the Temperature Thresholds of a Device

Setting the Temperature Thresholds of a Device

Function

This command is used to set the temperature thresholds of an SSD or controller.

Format

hioadm temperature -d devicename [-i index] -o overtemperature_threshold -u undertemperature_threshold

Parameters

Parameter Description Value
devicename Name of a device. Example: nvme0
index Number of a temperature sensor.
  • 0: overall temperature
  • 1 to 8: controller sensor number
NOTE:
If this parameter is not specified, all sensors are configured. In this scenario, if only one threshold is specified, the other threshold uses the threshold of the overall temperature. The current device has only one sensor.
overthreshold Overtemperature threshold.
  • Unit: K
  • Value range:
    • Overall temperature: 273K to 351K (0°C to 78°C)
    • Controller temperature: 273K to 373K (0°C to 100°C)

If this parameter is not specified, this parameter value is not changed. Either the overtemperature or undertemperature threshold must be specified.

NOTE:
ES3000 V3 SDDs have two alarm severities. The second alarm severity restricts disk I/O speed. If an overtemperature alarm occurs, check server heat dissipation and ambient temperature.
underthreshold Undertemperature threshold.
  • Unit: K
  • Value range:
    • Overall temperature: 273K to 351K (0°C to 78°C)
    • Controller temperature: 273K to 373K (0°C to 100°C)

If this parameter is not specified, this parameter value is not changed. Either the overtemperature or undertemperature threshold must be specified.

Usage Guidelines

None

Example

# Set the overtemperature and undertemperature thresholds to 333K and 273K for the nvme0 SSD.

[root@localhost tool]# hioadm temperature -d nvme0 -i 0 -o 333 -u 273
set overtemperature threshold successed. 
set undertemperature threshold successed. 
[root@localhost tool]# hioadm temperature -d nvme0
composite highest temperature:                335 degree Kelvin (62 degree Celsius) 
composite overtemperature count: 0 
composite overtemperature time:  0 min 
controller highest temperature:     341 degree Kelvin (68 degree Celsius) 
controller overtemperature count:  0 
controller overtemperature time:   0 min 
 
sensors temperature information in degree Kelvin (degree Celsius):
               current     over threshold     under threshold 
composite    303(30)       333 (60)            273(0) 
controller1  303(30)       358(85)              273(0)
