BMC UUID property/object not found

[CS20 CHMa0]

Hi Raj,
You can check the inventory service.
Ipmid return BMC UUID by get D-Bus property from inventory service.
And inventory service will read some configuration file while startup like
https://github.com/Nuvoton-Israel/openbmc/blob/runbmc/meta-quanta/meta-olympus-nuvoton/recipes-phosphor/configuration/olympus-nuvoton-yaml-config/olympus-nuvoton-ipmi-fru-bmc.yaml
If the FRU has no BMC UUID data or not configure BMC UUID in inventory service, the property would not exist.

Thanks,
Brian

Hi Raj,
The systemd get UUID function need Kernel API support.
Maybe you can check Kernel configuration first.

Hi,

I get below error message on "ipmitool mc guid" command,

Dec 24 05:09:33 obmc ipmid[1457]: Failed in reading BMC UUID property
Dec 24 05:09:42 obmc ipmid[1457]: No Object has implemented the interface
Dec 24 05:09:42 obmc ipmid[1457]: The operation failed internally.

Is this same as
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_openbmc_openbmc_issues_3532&d=DwMGaQ&c=ue8mO8zgC4VZ4q_aNVKt8G9MC01UFDmisvMR1k-EoDM&r=7g2D1XDc1ET3CnY1ySnaWQXPxPxfpLww1MiDbLW4v8Q&m=vHWR3IU3HAh0uFyTmxnEwOdlONHhW3FY4FTzZ01mjRU&s=tbhwa-ghqEmw4cfgUzsf61Iq4BcoU7fM0Biw94O50xQ&e=

Which app/service implements this interface?

Thanks

Raj
