  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Data Fabric Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Data Fabric gateway mediates one-way communication between a source HPE Data Fabric cluster and a destination cluster. You can replicate HPE Data Fabric Database tables (binary and JSON) and HPE Data Fabric Streams streams. HPE Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.

Starting the Services

Explains how to start services using either the Control System, the CLI or the REST API.

About this task

You can start one or more services using the Control System or the CLI if the service is not disabled. If the service is disabled, you must enable the service first, in order to start the service. See Enabling and Disabling a Service Using the CLI and REST API for more information.

Starting the Services Running on the Nodes Using the Control System

About this task

To start the services running on the nodes:

Procedure

Log in to the Control System and click Nodes to display the Nodes page.
NOTE
The Nodes page is not available on the Kubernetes version of the Control System.
Select the nodes from the list of nodes in the Nodes pane and click Manage Services to display the Manage Services window.
Choose the Start radio button for the services you wish to start on the selected nodes and click Save.

Starting the Services Running on a Node Using the Control System
