I found it much easier to ignore all the DataWarehouse stuff and used a
project called prometheus Ovirt Exporter, spun up in a docker host, and use
the prom datasource in Grafana. I was up and running with good Ovirt

It's a bit disheartening that HCI users don't have an easier upgrade path.

I have 3 nodes running node ng 4.3.9 with a gluster/hci cluster. How do I

- engine now at Version 4.3.6.7-1.el7

You have to add all the initiators for each node to the iscsi LUN. At
least thats how I got it working. Then I think it's recommended to setup
multipath.
However take this with a grain because iscsi did not work well for me.
