Applies to

  • ONTAP 9

Issue

  • CIFS clients cannot access share.
  • NFS client fails to mount a volume.
  • iSCSI host experiences disconnect to storage.
  • Periodically the SMB Connections are disconnected and not reconnected.
  • CIFS and NFS requests are not actually reaching to ONTAP but going to the other device having same IP address.
  • Vscan server disconnected and vscan connection-status show-not-connected shows - (hyphen instead of reason)
  • Management access to the cluster may be affected.
  • Duplicate IP address error messages can usually be seen in the event logs.
