Keeping odata IDs in redfish resources ?

[pyfontan]

Summary

I have a problem to identify network devices on HPe servers.
I would like to have a specific ID for each redfish resource.

Perhaps one should keep @odata.id in final resources.

Issue Type

Feature Idea

Component Name

redfish_info

Additional Information

With the following playbook:

    - name: Get Network card information
      community.general.redfish_info:
        category: Systems
        command: GetNicInventory
        baseuri: "{{ asset.manager.ip }}"
        username: "{{ asset.manager.user }}"
        password: "{{ asset.manager.password }}"
        timeout: "{{ redfish_timeout | default(omit) }}"
      register: rfnicinfo
      delegate_to: "{{manager_proxy_server}}"

We can have description of each Ethernet interface.

But as you can see, IDs are not unique... I've never seen that on DELL servers, but HPe did. :(

I would like to be able to specify an ID as a variable to my playbook. And in my use case, ID must be unique on a single server but can be the same on multiple servers of the same type. So MACAddress can't be used.

I thought that keeping the @odata.id in the resource would be a good idea ?

Yeah, I can see that coming up in other implementations too. Id is only guaranteed to be unique for a given resource collection (and not across the entire service). Having the full URI would be useful. I'd like to avoid calling it @odata.id in the output payload if possible.

[pyfontan]

@mraineri I started to write something for disks resources which is named RedfishURI (see #8937).
I'm thinking of implementing the same thing for network interfaces. Is it OK for you ?

[mraineri]

It's definitely in the right direction; I have one suggested addition in the PR to review, but I'm liking the changes so far!
