[phosphor-host-ipmid] Question about IPMI SDR

[Chris Chen (TPI)]

Hi all,

We have added 3 temp sensors by using entity-manager, and looks like we can list them with temp value reading successfully as below.

However, there is a kind of error message "Get SDR 0003 command failed: Invalid data field in request" always been shown behind it. I take a look at it via journal log in OpenBMC what error it is. That is:

I have tried to figure out it but with limited capability, can someone help to provide some suggestions for me? I mean how to fix it, or I'm able to ignore it because the SDR has been listed?

Thank you.
