 15.6.2 Commands in the Management Client
 ----------------------------------------
 
 In addition to the central configuration file, a cluster may also be
 controlled through a command-line interface available through the
 management client `ndb_mgm'. This is the primary administrative
 interface to a running cluster.
 
 Commands for the event logs are given in 
 mysql-cluster-event-reports. commands for creating backups and
 restoring from backup are provided in  mysql-cluster-backup.
 
 The management client has the following basic commands. In the listing
 that follows, NODE_ID denotes either a database node ID or the keyword
 `ALL', which indicates that the command should be applied to all of the
 cluster's data nodes.
 
    * `HELP'
 
      Displays information on all available commands.
 
    * `SHOW'
 
      Displays information on the cluster's status.
 
      * In a cluster where multiple management nodes are in use,
      this command displays information only for data nodes that are
      actually connected to the current management server.
 
    * `NODE_ID START'
 
      Starts the data node identified by NODE_ID (or all data nodes).
 
    * `NODE_ID STOP'
 
      Stops the data node identified by NODE_ID (or all data nodes).
 
    * `NODE_ID RESTART [-N] [-I]'
 
      Restarts the data node identified by NODE_ID (or all data nodes).
 
    * `NODE_ID STATUS'
 
      Displays status information for the data node identified by
      NODE_ID (or for all data nodes).
 
    * `ENTER SINGLE USER MODE NODE_ID'
 
      Enters single-user mode, whereby only the MySQL server identified
      by the node ID NODE_ID is allowed to access the database.
 
    * `EXIT SINGLE USER MODE'
 
      Exits single-user mode, allowing all SQL nodes (that is, all
      running `mysqld' processes) to access the database.
 
    * `QUIT'
 
      Terminates the management client.
 
    * `SHUTDOWN'
 
      Shuts down all cluster nodes, except for SQL nodes, and exits.
