If I assign management ports netapp03-01_mgmt and netapp03-02_mgmt to the same policy broadcast-domain-wide, is that correct?
Will they then be failover targets for each other?
No, sorry, there is still a misunderstanding.
Both LIFs (network interface show, Logic Interfaces, or IP Aliases or whatever you name it, you name it "management ports") are Node Management LIFs. Node Management LIFs have a special purpose, they are used by the node to access the management Network, e.g. to send out autosupport or for other different special purposes.
The thing is - it makes no sense for a "Node Management LIF" to leave (migrate off) the node it is managing at any time, it has to stay with the node, always. Similar to InterCluster LIFs or SAN LIFs as another example.
Your broadcast-domain "Default" (or the Failover Group "Default" which is identical to the Broadcast-Domain here as it always should be), does only contain one physical port per Node, e0M - netapp03-01:e0M and netapp03-02:e0M. This means each node has a physical Port, e0M, placed as possible failover targets into the broadcast-domain.
So both LIFs, LIF netapp03-01_mgmt for node netapp03-01 and LIF netapp03-02_mgmt for node netapp03-02, do have no option to failover - as each node does only have one port, e0M in broadcast-domain "Default". Please do again read my previous reply - I explained how other customers handle this and presented 3 options at the end of my reply that you can choose.
You currently have choosen none of theses options I have explained, because failover-policy is local-only but the LIF's broadcast-domain does only contain one single local (to the node) port - and this is why you experience the warning.
Failover-policy "cluster-wide" is no option for these two LIFs or more specific - for any LIF with role "node-mgmt" or role "intercluster" or role "data" with "data-protocol" being "iscsi" or "fcp" or "fc-nvme". For the cluster_mgmt LIF this is different - you can place this on any node as any node can manage the cluster but again, a node management LIF can never leave its node.
you can check the man page of network interface create via command "man network interface create":
-role {cluster|data|node-mgmt|intercluster|cluster-mgmt} - (DEPRECATED)-Role
Note: This parameter has been deprecated and may be removed in a future version of ONTAP. Use the -service-policy parameter instead.
Use this parameter to specify the role of the LIF. LIFs can have one of five roles:
o Cluster LIFs, which provide communication among the nodes in a cluster
o Intercluster LIFs, which provide communication among peered clusters
o Data LIFs, which provide data access to NAS and SAN clients
o Node-management LIFs, which provide access to cluster management functionality
o Cluster-management LIFs, which provide access to cluster management functionality
LIFs with the cluster-management role behave as LIFs with the node-management role except that cluster-management LIFs can failover between nodes.
