That is great Kasturi, thanks!
I will go over these steps just to make sure nothing is missing. But it loo=
ks the right way to do it. The only step that looks strange is the step 6 t=
o shutdown. I always though that if I shutdown a HA protected machine oVirt=
would then launch it back again. So in my thoughts I would do the step 6 b=
efore step 4. This said, am I missing something?

Hi,
You can follow the steps below to do that.
1) Stop all the virtual machines.
2) Move all the storage domains other than hosted_storage to maintenance wh=
ich will unmount them from all the nodes.
3) Move HE to global maintenance 'hosted-engine --set-maintenance --mode =
=3Dglobal'
4) stop HE vm by running the command 'hosted-engine --vm-shutdown'
5) confirm that engine is down using the command 'hosted-engine --vm-status=
'
6) stop ha agent and broker services on all the nodes by running the comman=
d 'systemctl stop ovirt-ha-broker' ; 'systemctl stop ovirt-ha-agent'
7) umount hosted-engine from all the hypervisors 'hosted-engine --disconnec=
t-storage'
8) stop all the volumes.
9) power off all the hypervisors.
To bring it up back again below steps will help.
1) Power on all the hypervisors.
2) start all the volumes
3) start ha agent and broker services on all the nodes by running the comma=
nd 'systemctl start ovirt-ha-broker' ; 'systemctl start ovirt-ha-agent'
4) Move hosted-engine out of global maintenance by running the command host=
ed-engine --set-maintenance --mode =3Dnone
5) give some time for the HE to come up. check for hosted-engine --vm-statu=
s to see if HE vm is up.
6) Activate all storage domains from UI.
7) start all virtual machines.
Hope this helps !!!
Thanks
kasturi.

Hi Moacir,
First switch off all VMs.
Second you need to declare hosts maintenance mode, don't start with SRM (of=
course if you are able use the ovirt-engine), it will ask you to shutdown =
the glusterfs on a machine.
Third if all machines are in maintenance mode, you can start shutting down =
them.
If you have hosted engine setup follow this [1]
Cheers
Erekle

VM is running but the hosted-engine.
Thanks for sharing your knowledge.
