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
which will unmount them from all the nodes.
3) Move HE to global maintenance 'hosted-engine --set-maintenance
--mode =global'
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.
