Alarm Parameter Description

Alarm Parameter Description

When you change an alarm threshold value, the new value may be out of range due to correlations between thresholds (for example, a lower threshold value must be less than an upper threshold value). If this happens, adjust the positive and negative hysteresis values for the sensor. For details about how to query and set the positive and negative hysteresis values for a sensor, see "Querying and Setting Positive Hysteresis Values for a Sensor (positivehysteresis)" and "Querying and Setting Negative Hysteresis Values for a Sensor (negativehysteresis)" in the KunLun Mission Critical Server V100R001 CMC User Guide.

For example, the value of lowercritical must be greater than that of lowernonrecoverable and smaller than that of lowernoncritical.

Observe the following threshold setting rules:

  • Upper threshold rules
    • If a value (for example, the value of lowernoncritical) higher than the value of lowercritical has not been set for a sensor, the upper limit is 127 (signed value) or 255 (unsigned value).
    • If a value higher than the value of lowercritical has been set for a sensor, the upper limit is as follows: Minimum threshold value - Positive hysteresis value - Negative hysteresis value - 1
  • Lower threshold rules
    • If lowernonrecoverable has been set for a sensor, the lower limit is as follows: Value of lowernonrecoverable + Negative hysteresis value + 1
    • If lowernonrecoverable has not been set for a sensor, the lower limit is –128 (unsigned value) or 0 (signed value).
NOTE:
  • In theory, the values of lowernonrecoverable, lowercritical, lowernoncritical, uppernoncritical, uppercritical, and uppernonrecoverable are in ascending order.
  • To set the positive and negative hysteresis values for a sensor, run the following commands:

    smmset -l bladeN -t sensor -d positivehysteresis -v value

    smmset -l bladeN -t sensor -d negativehysteresis -v value
