ONTAP System Manager reports initiators not logged into one node after switchback
Applies to
- ONTAP 9.12.1P4, 9.14.1P6
- 4-node MetroCluster
- FC
Issue
- After planned switchover/switchback, System Manager reports
Node "node2" has no logged-in initiators.:
- Specific initiators report they are only connected to LIF of one node:
- Over CLI, initiators show
wwpn-logged-into LIF which shows not connected in GUI:
vserver fcp ping-initiator show -vserver svm_windows -wwpn 21:00:34:80:0d:12:34:56 -lif lif4 -node node2 Vserver: svm_windows Remote WWPN: 21:00:34:80:0d:12:34:56 LIF Name: lif4 Node: node2 Ping Status: reachableExtended Status: wwpn-logged-in- Initiators also show logged into the LIF with
vserver fcp initiator show:

- When a LIF is bounced, EMS reports initiators logging into the node, but the GUI still reports the same issue:
[node2: fct_tpd_work_thread_0: scsitarget.fct.portLogin:notice]: Login at target FC port: '0h' by initiator port: '21:00:34:80:0d:12:34:56' address 0x20800. The target virtual port is: 'NetApp FC Target Port (8324) svm_windows:lif4'.- Windows shows all expected paths to both nodes with
