<div dir="ltr">Just found this in the RHV docs. I think sections 2.8 to 2.12 cover everything you could wish to know about SPM process. It made it clear for me anyway.

<p>How do you make the new cluster to use the same storage domain as
the original one ? Storage Domains in oVirt are a bit confusing
and less flexible and I am not sure it allows it, does it ?<br>

</div>
<div>I'm in the process of building a second ovirt cluster
within the default DC. This new cluster will use the same
storage domains as the original cluster, and I will slowly
migrate VMs from the old cluster to the new.</div>
<div><br>
</div>
<div>Given that the old and new cluster hosts have a firewall
between them I need to ensure that all relevant ports are
open, with particular attention to the correct operation of
SPM.</div>
<div><br>
</div>
<div>Is it sufficient to open TCP ports 16514 and 54321 to
achieve this?</div>
