If all servers with StarWind VSAN installed should be turned off, follow the steps below:
1. Shutdown the VMs, services, and roles running in the cluster and/or located on StarWind storage.
2. In StarWind Management Console, check that all StarWind HA devices have the “Synchronized” status on all servers.
3. Activate Maintenance Mode for all StarWind HA devices; this feature is available starting from the 8.0.11818 build. This will allow avoiding the full synchronization process after servers are back online.
The step-by-step guide for enabling StarWind Maintenance Mode can be found here.
4. Shut down the servers and VMs with StarWind VSAN installed.
5. When servers with StarWind VSAN are started again, disable Maintenance Mode for all StarWind HA devices.
6. Check that all StarWind HA devices have the “Synchronized” status on all servers.
7. Navigate to the cluster and start the VMs, services, and roles.
