I just got to a new customer and this is something I found early on... in short, clus1, clus3 and clus4 all show as being homed on e0a for the same node. I see this for other systems where clus1 and clus2 may be the only cluster ports (FAS62xx) and both show homed on e0c, for example.
Vserver Name | Cluster | Cluster | Cluster | Cluster |
Logical Interface Name | node1_clus1 | node1_clus2 | node1_clus3 | node1_clus4 |
Role | cluster | cluster | cluster | cluster |
Data Protocol | none | none | none | none |
Home Node | node1 | node1 | node1 | node1 |
Home Port | e0a | e0b | e0a | e0a |
Current Node | node1 | node1 | node1 | node1 |
Current Port | e0a | e0b | e0a | e0a |
Operational Status | up | up | up | up |
Numeric ID | 1024 | 1023 | 1035 | 1034 |
Is Home | TRUE | TRUE | TRUE | TRUE |
Network Address | 169.254.2.171 | 169.254.2.172 | 169.254.2.173 | 169.254.2.174 |
Netmask | 255.255.0.0 | 255.255.0.0 | 255.255.0.0 | 255.255.0.0 |
Administrative Status | up | up | up | up |
Any ideas as to why this might be?

I'm curious as to how the FAS62xx ended up with four cluster LIFs in the first place. Best practices only require 2 cluster ports and LIFs.
Regardless, if you really only have 2 cluster ports e0a and e0b, just delete the 2 extra LIFs. Make sure you end up with a cluster LIF home-ported on each port.

More info... from ASUP for node1, ifconfig -a section:
