Checking Node and Unity Registration in the Windows DNS - Advanced SQL Engine - Teradata Database

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.
