<pre>Hi all,
A while ago I had some problem with hosted-engine network which wasn't set
correctly at deploy time, so I finally decided to redeploy the hosted engine
in the hope the network will be set correctly this time. I've followed this
procedure:
Stop all VMs
Full backup of HE DB and export to safe place
Cleanup HE storage following <a class="gmail-m_-1388566559526568039moz-txt-link-freetext" href="https://access.redhat.com/solutions/2121581" target="_blank">https://access.redhat.com/<wbr>solutions/2121581</a>
Reboot Hosts
Re-deploy HE until DB recovery
Recover DB adding the following param:
--he-remove-storage-vm Removes the hosted-engine storage
domain, all its entities and the hosted-engine VM during restore.
--he-remove-hosts Removes all the hosted-engine hosts
during restore.
Finalize HE deployment.
Everything did run without errors and I'm able to access Web UI.
But now I don't see my HE VM and its respective Storage Domain, the logs
says it isn't able to import it. I see all other SD and I'm able to manage
my VMs as before.
Please find attached engine.log

<pre>I guess you can try to remove this disk/lun from the engine and let it retry.</pre>
</blockquote></span>
Could let me know how to remove that lun from the engine?<span class="gmail-"><br>
<blockquote type="cite">
<pre>If the only disk is of the hosted-engine, I guess it should have been
removed by '--he-remove-storage-vm' - if so, please open a bug
describing your flow in detail. Thanks.</pre>
</blockquote></span>
It seems that this option didn't remove the he storage information
and that this VG is still the old one.<br>
<br>
Many thanks for your help<br>
