Hi ,

=C2=A0=C2=A0=C2=A0 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 which will unmount them from all the nodes.

3)=C2=A0 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 command 'systemctl stop ovirt-ha-broker' ; 'systemctl stop ovirt-ha-agent'

7) umount hosted-engine from all the hypervisors 'hosted-engine --disconnect-storage'

8) stop all the volumes.

9) power off all the hypervisors.

Hope this helps !!!

Thanks

kasturi.
