Change iLO hostname using RedFish API

[bradawk1]

I'm searching through iLO RedFish API , but have not found the answer yet.  We have about 600 new servers with iLO interface names as set at the factory.  We want to change them to our naming convention.  I know how to change it with hponcfg, but don't want to have to log in to every server to run that.  Does anyone know the correct RedFish API call to change the ilO hostname?

OK, I found :

curl --insecure --silent --header "X-auth-Token: ${iLOAuth}" --request GET ${iLOSSO}/redfish/v1?$expand=* | jq -r '.'

gives in part:

"Oem": {
        "Hpe": {
            "@odata.type": "#HpeiLOServiceExt.v2_0_0.HpeiLOServiceExt",
            "Links": {
                "ResourceDirectory": {
                    "@odata.id": "/redfish/v1/ResourceDirectory/"
                }
            },
            "Manager": [
                {
                    "DefaultLanguage": "en",
                    "FQDN": "edited",
                    "HostName": "ILO",

I'm just not sure how to get down to the Manager array under Oem/Hpe.  Does anyone have an idea?

I figured it out.  Can see the current iLO hostname with:

curl --insecure --silent --location --header "X-Auth-Token: ${iLOAuth}" --request GET ${iLOSSO}/redfish/v1/Managers/1/NetworkProtocol | jq -r '.'

Then to change, I ran:

SERVER=new-ilo-hostname
echo '{"HostName": "'${SERVER}'"}' > set-ilo
curl --insecure --silent --location --include --header "Content-Type: appliation/json" --header "X-Auth-Token: ${iLOAuth}" --data "@set-ilo" --request PATCH ${iLOSSO}/redfish/v1/Managers/1/NetworkProtocol

I got back:

HTTP/1.1 200 OK

When I ran the GET call again, the hostname has been changed!
