If you get a Connection to system unsuccessful warning message when adding a Vantage system in the BAR Setup portlet, the DSC vNode may not be able to resolve the Vantage COP entries. To resolve this issue, you can verify the servers and domains configured in Viewpoint are also configured in the DSC vNode.
  1. SSH into Viewpoint and extract the DNS servers and search domains.
    1. Extract the DNS servers, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SERVERS" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SERVERS="153.64.251.200 153.65.8.10"
    2. Extract the DNS search domains, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SEARCHLIST" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SEARCHLIST="td.teradata.com teradata.com"
  2. SSH into the DSC vNode to check the DNS servers and search domains, and then add the servers and domains that are in Viewpoint.
    1. Extract the DNS servers, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SERVERS" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SERVERS="153.64.251.200"

      Notice if 153.65.8.10 is missing from Viewpoint.

    2. Add any missing servers:
      # sed -i "s/^NETCONFIG_DNS_STATIC_SERVERS=.*$/NETCONFIG_DNS_STATIC_SERVERS=\"153.64.251.200 153.65.8.10\"/" /etc/sysconfig/network/config
    3. If you added a server, verify it is now there, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SERVERS" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SERVERS="153.64.251.200 153.65.8.10"
    4. Extract the DNS search domains, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SEARCHLIST" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SEARCHLIST="labs.teradata.com"

      Notice if td.teradata.com and teradata.com are missing from Viewpoint.

    5. Add any missing search domains:
      # sed -i "s/^NETCONFIG_DNS_STATIC_SEARCHLIST=.*$/NETCONFIG_DNS_STATIC_SEARCHLIST=\"labs.teradata.com td.teradata.com teradata.com\"/" /etc/sysconfig/network/config
    6. If you added a search domain, verify it is now there, as in the following example:
      # grep "NETCONFIG_DNS_STATIC_SEARCHLIST" /etc/sysconfig/network/config
      NETCONFIG_DNS_STATIC_SEARCHLIST="labs.teradata.com td.teradata.com teradata.com"
    7. Apply the change:
      /sbin/netconfig update -f
    If the warning message continues, the DNS server may not contain any DNS record for the Vantage COP entries.
  3. Extract the Vantage COP entries from the hosts file in Viewpoint and append them to the hosts file in the DSC vNode using the following syntax:
    # grep TeradataSystemNamecop* /etc/hosts | ssh root@DSC_public_ip 'cat >> /etc/hosts'

    For example, if the TeradataSystemName is system1 and the public IP for the DSC vNode is 10.25.23.170, use the following syntax:

    # grep system1cop* /etc/hosts | ssh root@10.25.23.170 'cat >> /etc/hosts'
