Redfish HealthRollup/LED question

[Deepak Kodihalli]

Hi James/Gunnar,

On IBM platforms, a fault indicator LED associated with a FRU can 
indicate the "Health Rollup" status of the FRU. For eg a CPU can be 
healthy, but something contained within (eg a core) may be broken, so 
the LED will be turned on. I think the Redfish HealthRollup property is 
conceptually similar.

Question is - do you see a problem if we add code in bmcweb that sets 
the HealthRollup property for a FRU if an associated LED is turned on? I 
believe this is aligned with 
https://github.com/openbmc/docs/blob/master/designs/redfish-health-rolllup.md 
(no new D-Bus objects/interfaces being added, etc). On IBM platforms, a 
D-Bus association might exist between the FRU and the LED, and setting 
the HealthRollup property will be based on this. If the said association 
is missing on other platforms, the code will not do anything.

Thanks,
Deepak
