9.2. Enabling Global Maintenance Mode
You must place the self-hosted engine environment in global maintenance mode before performing any setup or upgrade tasks on the Manager virtual machine.
Log in to one of the self-hosted engine nodes and enable global maintenance mode:
# hosted-engine --set-maintenance --mode=global
Confirm that the environment is in maintenance mode before proceeding:
# hosted-engine --vm-status
You should see a message indicating that the cluster is in maintenance mode.
