Host might lose iSCSI LUN connection during ONTAP takeover if no iSCSI lifs on where the LUN owned high availability (HA) pair
Applies to
- iSCSI
- SAN
- ONTAP 9
Issue
- 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
- Create LUN on node N1
- Create one iSCSI lif interface for each node
- Configure all 4 nodes as SLM eporting-nodes
- Delete the lifs from N1 and N2
- Reboot node N1 or N2
- iSCSI host will lose LUN connection and system will hang
