Starting up and shutting down the cluster

To shut down or start the cluster, we recommend contacting Technical Support. Do not shut down or start the cluster if you encounter problems with application health.

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. In a browser on any computer on which access to the Central Node server has been allowed, enter the IP address of the server with the Central Node component into the browser's address bar.

   If you are using the high availability version of the application, you can enter the IP address of any server of the Central Node cluster or the fully qualified domain name (FQDN) of the cluster.

   To ensure uninterrupted access to the program web interface, you can configure the Round Robin function on the DNS server. To do this, log in to the web interface of the first healthy server of the Central Node cluster.

   An input window for account credentials of the Kaspersky Anti Targeted Attack Platform user opens.

2. Enter the administrator user name "admin" and the password that was set during installation of the application.
3. Select the Local administrator check box.
4. Click Log in.

   This opens a web interface window in which you can manage application sizing.

5. Go to the Cluster section.
6. Click the Shut down button.

The main components of the application are 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.
