Unable to resolve failover redundancy alert

HUX20002000 — Mon, 21 Apr 2025 18:49:27 GMT

I received this error: "vifmgr.lifs.noredundancy: No redundancy in the failover configuration for 2 LIFs...This message occurs when one or more logical interfaces (LIFs) are configured to use a failover policy that implies failover to one or more ports but have no failover targets beyond their home ports."

The error applies to the node management LIFs on the two nodes (node1_mgmt, node2_mgmt) and also the two custom replication LIFs I created (node1_replication, node2_replication). The replication LIFs are talking to a NetApp in a different datacenter.

Here are the failover settings for the node management LIFs:

Logical Home Failover Failover
Vserver Interface Node:Port Policy Group
-------- ---------- --------- ---------- ---------------
Clus node1_mgmt node1:e0M local-only Management
Failover Targets: node1:e0M
node2_mgmt node2:e0M local-only Management
Failover Targets: node2:e0M

The replication LIFs have a similar config:

Logical Home Failover Failover
Vserver Interface Node:Port Policy Group
------- --------------- ------------- ---------- ---------------
Repl node1_replication_dcpn node1:e0e-202 local-only Repl_VLAN_202
Failover Targets: node1:e0e-202
node2_replication_dcpn node2:e0e-202 local-only Repl_VLAN_202
Failover Targets: node2:e0e-202

Here are the failover group settings:

Vserver Group Targets
------- ---------- --------------------------------------------
Clus Management node1:e0M, node2:e0M
Repl Repl_VLAN_202 node1:e0e-202, node2:e0e-202

As far as I can tell, the error is occurring because "Failover Targets" shows only one target for each LIF — the LIF's home port.

Is there something I've missed here? Something I need to do to tell it that it can failover those LIFs to the corresponding ports on the other node?

Or, looking at it a different way: is it even possible for management and replication (i.e. intecluster) LIFs to failover? If not, then is there something I need to change so that this alert condition will ignore these LIFs?

The easy fix is to set the failover policy to disabled

net int modify -vserver Clus -lif *mgmt -failover-policy disabled

net int modify -vserver Repl -lif *repl* -failover-policy disabled

the node management don’t have anywhere to failover so it’s fine to set them to disable.
for the repl lifs if they are in fact on a port channel then disabling the failover on those is ok. Intercluster lifs can only fail over to the same node. Since there is a port channel, failover should be built in

hello：

Then the failover policy of LIF can be changed from local only to disabled.

network interface modify -vserver <vserver> -lif <lif_name> -failover-policy disabled

Best regards
