Applies to

  • ONTAP 9
  • NFS
  • CIFS

Issue

  • While clients are performing CIFS/NFS operations, they report intermittent disconnects
  • No errors are present from ONTAP
  • The clients do not reside locally on the LIF's subnet
  • A packet trace shows that ONTAP stops responding to the client requests after the gateway fails to respond to ONTAP's ARP request
  • Access is restored without further intervention after the gateway eventually responds to the ARP requests (historically this has been observed as a ~30 second outage)
