To check sensor information, use the following command:
root@dellemc-diag-os:~# ipmitool sensor list
To change the sensor threshold, see the IPMI Specification v2.0 chapter 35.8 Set Sensor Thresholds Command.
● Request data byte 1—Sensor number, FFH=reserved
● Request data byte 2—
○ [7:6] - reserved. Write as 00b
○ [5] - 1b=set upper non-recoverable threshold
○ [4] - 1b=set upper critical threshold
○ [3] - 1b=set upper non-critical threshold
○ [2] - 1b=set lower non-recoverable threshold
○ [1] - 1b=set lower critical threshold
○ [0] - 1b=set lower non-critical threshold
● Request data byte 3—lower non-critical threshold. Ignored if bit 0 of byte 2 = 0
● Request data byte 4—lower critical threshold. Ignored if bit 1 of byte 2 = 0
● Request data byte 5—lower non-recoverable threshold. Ignored if bit 2 of byte 2 = 0
● Request data byte 6—upper non-critical threshold. Ignored if bit 3 of byte 2 = 0
● Request data byte 7—upper critical threshold value. Ignored if bit 4 of byte 2 = 0
● Request data byte 8—upper non-recoverable threshold value. Ignored if bit 5 of byte 2 = 0
● Response data byte 1—Completion code
