Host might lose iSCSI LUN connection during ONTAP takeover if no iSCSI lifs on where the LUN owned high availability (HA) pair

Last Updated:

Applies to

  • iSCSI
  • SAN
  • ONTAP 9


  • iSCSI lifs were deleted from high availability (HA) pair in which the LUN was located  
  • Clients access iSCSI LUN through the indirect path on other HA pair
  • iSCSI client will lose iSCSI LUN connection during ONTAP takeover or node rebooting

For example:

There is a 4-node cluster, node N1 and N2 for one HA pair, N3 and N4 form another HA pair

  1. Create LUN on node N1
  2. Create one iSCSI lif interface for each node
  3. Configure all 4 nodes as SLM eporting-nodes 
  4. Delete the lifs from N1 and N2
  5. Reboot node N1 or N2
  6. iSCSI host will lose LUN connection and system will hang
