ONTAP 9

Issue

  • A migration from a different storage system (such as a Data ONTAP 7-Mode controller) is complete and the DNS A record is modified so that the original name maps to a IP address of a CIFS SVM data LIF
  • On attempting to access the CIFS server using \\CIFSSVM there is a hang and timeout followed by a generic network path not found error
  • Ping or nslookup of the DNS name is successful and using the IP address works
  • Logging on and off, clearing DNS cache, or rebooting the client does not help
