Verifying DNS server status

Beginning in ONTAP 9.2 and later, you should verify the status of your Domain Name Service (DNS) server before and after performing a nondisruptive upgrade.

About this task

The task does not apply if you are upgrading from ONTAP 9.1 or earlier.


  1. Check the status of your DNS servers: dns check -vserver vserver_name
    An up status indicates the service is running. A down status indicates that the service is not running.
  2. If the DNS server is down, modify it: dns modify -vserver vserver_name -domains domain_name -name-servers name_server_ipaddress
  3. Verify the status of the DNS server is up.
