On an Exadata compute/database server, check temperature through the server’s ILOM service processor. CellCLI is for storage cells; it is not the compute server’s sensor interface. Oracle: Exadata ambient temperature monitoring

Ambient intake temperature on one node:

ipmitool sunoem cli "show /SYS/T_AMB"

Look for the value in °C and the sensor’s alarm_status.

List temperature sensors:

ipmitool sdr list | grep -iE 'ipmitool sdr list | grep degrees'

Example:

ipmitool sdr list | grep degrees

T_IN_ZONE0 | 40 degrees C | ok
T_IN_ZONE1 | 43 degrees C | ok
T_IN_ZONE2 | 37 degrees C | ok
T_IN_ZONE3 | 43 degrees C | ok
T_OUT_ZONE0 | 41 degrees C | ok
T_OUT_ZONE1 | 44 degrees C | ok
T_OUT_ZONE2 | 43 degrees C | ok
T_OUT_ZONE3 | 47 degrees C | ok
PS0/T_IN | 44 degrees C | ok
PS0/T_OUT | 47 degrees C | ok
PS1/T_IN | 42 degrees C | ok
PS1/T_OUT | 48 degrees C | ok
T_AMB | 31 degrees C | ok

For sensor readings and thresholds, Oracle ILOM also documents ipmitool sensor; available sensors depend on the server model. Oracle ILOM: Display sensor list · Oracle ILOM: IPMItool commands

Check ILOM health and open hardware problems from the ILOM CLI:

show /System health
show /System/Open_Problems
show /SYS/T_AMB

Oracle’s Exadata guidance gives a rack ambient operating range of 5–32 °C, with 21–23 °C as the optimal range. Those are ambient conditions; use each sensor’s reported status and thresholds for component sensors.
