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"

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.
