Check if Vantage nodes, and the Unity server, if used, are registered in DNS.

  1. From the command prompt on a Teradata Vantage Advanced SQL Engine database node, or from the Linux prompt on a Unity server, run nslookup using the naming convention for your system:
    nslookup [node_name|unity_server_name]
  2. Additional action is based on the output returned by nslookup:
    • If a node or Unity server is not properly registered in DNS, for example,
      nslookup tdatsysa1-1
      Server:         141.206.3.8
      Address:        141.206.3.8#53
      
      ** server can't find tdatsysa1-1: SERVFAIL

      do the following step Adding Database Nodes and Unity Servers to UNIX DNS.

    • If all nodes and Unity servers are properly registered in DNS, they appear in the results from the nslookup command, for example,
      nslookup node_name
      Server:         141.206.3.8
      Address:        141.206.3.8#53
      
      Name: tdatsysa1-1.corp.teradata.com
      Address: 141.206.3.58

      go to Creating an Active Directory User for Each Node and Unity Server.
