How to check whether voltage sensor is enabled or disabled in T5220

Question

Hi,
I use command "prtdiag -v" to check current system status in two T5220 servers. However, I find a strange thing in sensors part as below, which Server one has status info for temperature and voltage sensors but Server two has no related info.
Does it mean the voltage and temperature senors are disabled? How do I check whether voltage sensor is enabled or disabled in T5220?
Note:
Server one has output by command 'prtpicl -c voltage-sensor -v', but Server two has nothing.

Server one has status info for temperature and voltage sensors but Server two has no related info.You are using the prtdiag command as root user whenever you are doing this?
The output when done as root will give full information, whereas if you are NOT the root user the output will almost always have less information.
However ...
Because you have stated that the prtpicl information also seems to follow the same more-versus-less symptoms, I suspect you have a patch level issue.
Server #2 is probably under-patched when compared to server #1 (both for system OBP level as well as OS level).
Determining if that is the root of your issue is too much for a forum thread.
Run Explorer on both systems then use your service contract credentials to log a SR so that Technical Support can analyze those Explorer files for you.
