回覆: [phosphor-host-ipmid] Question about IPMI SDR

[Chris Chen (TPI)]

Hi all,

I think I figured out the error message is due to the phosphor-health-monitor package. The phosphor-health-monitor doesn't have the interface of org.freedesktop.DBus.ObjectManager and with the GetManagedObjects method call, so the getSensorMap() in the intel-ipmi-oem would be failed.

As I know, the phosphor-health-monitor is a part of the base phosphor package. But there are some questions in my mind still and would like to get help here.

  1.
is it only for monitoring CPU and memory sensor values?  it looks like there is no explanation of it is in the phosphor-health-monitor repo.
  2.
can I remove it? If yes, will I miss any features?

Thanks

Chris Chen

主旨: [phosphor-host-ipmid] Question about IPMI SDR

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.
