Starting up and shutting down the cluster

If you want to power off the healthy servers in the cluster, you must first shut down the cluster to avoid data loss.

To shut down a cluster:

1. Log in to the web interface for sizing management.
2. Go to the Cluster section.
3. Click the Shut down button.

The operation of the program's main components will be stopped. You can now power off the cluster servers.

To start up the cluster servers:

1. Disconnect power to the servers if it has not been previously disconnected.
2. Power on the storage server.
3. Power up the remaining servers.

The cluster servers will start up.

The scaling management web interface becomes available when more than half of the cluster servers are started. For example, if there are 7 servers in the cluster, the web interface will be available when 4 servers of the cluster are powered on.
