The switch has a total of eight fans numbered zero to seven, with two fans in each of four fan modules. Fan modules are numbered zero to three, so fans zero and one would be in the first fan module (FM0), fans two and three would be in the second fan module (FM1), and so on.
-> show -d properties /SYS/FM_slot/PRSNT
where slot is the slot of the fan (0 to 3) for which you want to display information.
For example, to determine the presence of fan module 0, type:
-> show -d properties /SYS/FM0/PRSNT /SYS/FM0/PRSNT Properties: type = Entity Presence ipmi_name = FM0/PRSNT class = Discrete Sensor value = Present alarm_status = cleared ->
-> show /SYS/FM0/SERVICE
/SYS/FM0/SERVICE
Properties:
type = Indicator
ipmi_name = FM0/SERVICE
value = Off
->
-> show -d properties /SYS/FM0 /System/Cooling/Fans/Fan_0 Properties: type = Fan Module ipmi_name = FM0 fault_state = OK clear_fault_action = (none) ->
-> show -d properties /SYS/FM0/Fan_X
where X is the number of the fan (0 to 1 for FM0) for which you want to display information.
For example, to display information for fan 1:
-> show -d properties /SYS/FM0/FAN1 /SYS/FM0/FAN1 Properties: type = Fan Module ipmi_name = FM0/FAN1 fault_state = OK clear_fault_action = (none) ->
-> show -d properties /System/Cooling/Fans/Fan_X
where X is the number of the fan (0 through 7). Fan information displayed is for the chassis cooling subsystem, not for component cooling such as power-supply fans.
For example, type:
-> show -d properties /System/Cooling/Fans/Fan_1 /System/Cooling/Fans/Fan_1 Properties: health = OK health_details = - part_number = Unknown serial_number = Unknown location = FM0 (Fan Module 0) fan_percentage = 33% ->
-> show -d properties /SYS/FMY/FANX/TACH
where X is the number of the fan you want to display for a specific fan module Y.
-> show -d properties /SYS/FM0/FAN1/TACH /SYS/FM0/FAN1/TACH Properties: type = Fan ipmi_name = FM0/FAN1/TACH class = Threshold Sensor value = 10000.000 RPM upper_nonrecov_threshold = 25000.000 RPMN upper_critical_threshold = 25000.0000 RPM upper_noncritical_threshold = 24000.000 RPM lower_noncritical_threshold = 6300.000 RPM lower_critical_threshold = 6000.000 RPM lower_nonrecov_threshold = 0.000 RPM alarm_status = cleared ->
