1. Any body know what those parameters of simple update action are used for? Please give some examples of parameter ImageURI and Target.
2. What the fw action flow when user give a POST to /redfish/v1/UpdateService/Action/SimpleUpdate
Thanks a lot
There are three parameters defined for the SimpleUpdate Action. Looking at the latest JSON Schemas, I'm not seeing them documented (they are in the CSDL XML, however), so that needs to be investigated and corrected. But they are defined as:
The network protocol used by the Update Service to retrieve the software image file located at the URI provided in ImageURI, if the URI does not contain a scheme.
The URI of the software image to be installed.
The array of URIs indicating where the update image is to be applied.
ImageURI is the critical parameter here. Many implementations will apply the image to the relevant device(s) without specifying (or even supporting) the "Targets" parameter.
The firmware flow upon receipt of a POST here will depend a lot on the implementation and what is being updated.
