RH-OSP 12 Director with Redfish and Cisco IMC v3.0(4a)

Hi - I'm trying to get RH-OSP 12 Director / Ironic to manage a Cisco UCS C460M4 standalone server running 3.0(4a) firmware with Redfish enabled for system management. The servers are associated and enabled for management via Ironic, but when I try to do Introspection the servers will not reboot to load the Introspection image because the RH Ironic / Redfish combo is looking for the Action 'ComputerSystem.Reset' but the CIMC appears to implement instead just 'System.Reset'. The Redfish specification / site seems to show both implementations in various places.

Which is right? Is there a way to cause one or the other of the two sides to reference the same action?

Via the RH 'openstack baremetal node show <ID>' I see:

    The action #ComputerSystem.Reset is missing from the resource /redfish/v1/Systems/<ID>

By exploring the API tree on the CIMC I see:

    "Actions":{
        "#System.Reset":{
        "Target":"/redfish/v1/Systems/<ID>/Actions/System.Reset",
        "ResetType@Redfish.AllowableValues":["On","ForceOff","GracefulShutdown","ForceRestart","Nmi"]
        }
    }

This is a blocker. Can anyone suggest a troubleshooting or remediation step?  Apologies if this is the wrong room for this discussion.

Thanks.
