Thanks for all your information.
I created a linux script as per details below.
Attached to this email (some info purged)
Gentlemen, we have a disk now!
I'm marking the post as solved ... even though we do not know where the disk
gone in these weeks yet.
Probably unexpected vacation @Cuba? This disk won't reclaim expenses though
I will create a test VM and perform some tests in the future with the
expansion feature
Thank you for all your support

Hi Andrea,
I'm using "postman" chrome-extension to execute my REST requests.
For firefox the rest-client add-on you can use is
https://addons.mozilla.org/de/firefox/addon/restclient/
Juan, do we have a wiki for step by step instructions of REST
Regards,

I'd suggest to try a command line client, as it is easier to share the
results and check what is going wrong. You can use the "curl" command, for
example. Assuming that you already know the identifiers of the storage
domain and of the disk to register it should be something like this:
---8<---
#!/bin/sh -ex
url="https://yourengine/ovirt-engine/api"
user="your user"
password="your password"
storage_domain_id="the storage domain id"
disk_id="the disk id"
curl \
--verbose \
--insecure \
--user "${user}:${password}" \
--request POST \
--header "Content-Type: application/xml" \ --header "Accept:
application/xml" \ --data "
<disk id=\"${disk_id}\"/>
" \
"${url}/storagedomains/${storage_domain_id}/disks;unregistered"
--->8---
