best way to do host maintenance

Hi

What is the best way to take down one host from the scaleIO cluster in order to do some maintenance on it?

I will put the host in maintenance mode so the vm's will be migrated off - do i put the host in maintenance mode then in the scaleIO GUI ? and then reboot the host to do the maintenance ?

or is there any need to put it in maintenance mode in the scale IO gui ?

Once i bring the host back up then and take out of maintenace mode i will let the cluster rebalance and then start the same procedure one by one on the other hosts ?

does this sound right ?
