Hi,
Can someone please provide an example request to edit the power management options of a host?
Ie. the options contained in host['power_management']['agents']['agent'][0]['options']['option'] and host['power_management']['options']['option']
Currently I have:
"option": [ { "name": "power_wait", "value": "4" }, { "name": "lanplus", "value": "" } ]
I need to change the value of "lanplus" from nothing to 1 or "on".
I have tried replacing the entire host['power_management']['options'] set and the host['power_management']['agents'] set with PUT requests to the API endpoint for the host, with no change or errors - I just get a 200 OK response with the details of the host as if I had just done a GET request.

Apparently you are using version 3.6 or older of the engine, because in newer versions (4.0 and newer) the 'power_management/agents' and 'power_management/options' aren't populated. Anyhow, that information is read only. To write it you need to use the hosts/{host:id}/fenceagents/{agent:id} endpoint. For example, to change the value of 'lanplus' to 1 you can use an script like this (using curl): ---8<--- #!/bin/sh -ex url="https://rhevm36.example.com/ovirt-engine/api" user="admin@internal" password="redhat123" curl \ --verbose \ --cacert /etc/pki/ovirt-engine/ca.pem \ --request PUT \ --user "${user}:${password}" \ --header "Version: 3" \ --header "Content-Type: application/json" \ --header "Accept: application/json" \ --data ' { "options" : { "option" : [ { "name" : "power_wait", "value" : "4" }, { "name" : "lanplus", "value" : "1" } ] } } ' \ "${url}/hosts/136e39d6-7047-4ad0-87c8-d3028189ae8a/fenceagents/a16ff2fe-066c-4837-8b96-bd393bd7d3d7" --->8--- Note that this is using version 3 of the API, which is deprecated since version 4.0 of the engine, and will be removed in version 4.2. Consider migrating to version 4 of the API once you upgrade your environment to version 4.0 or newer of the engine.
