AFF A250 systems use25GbE ports with breakout cablingfor cluster and HA traffic. When adding these nodes to switches running a standard Cluster-HA RCF, the switches must be updated to aCluster-HA-Breakout RCFto support breakout ports. The nodes must then be cabled to the breakout ports. Therefore,B and Dare correct.

In ONTAP, LIF failover target selection is controlled byfailover groupsandfailover policies. A key installation and validation concept is that ONTAP uses broadcast domains to simplify and automate failover-group membership. Specifically, ONTAP documents that when you create a broadcast domain, ONTAP automatically creates a failover group with the same name and manages it so that as ports are added or removed from the broadcast domain, they are also added or removed from the associated failover group.

Because of this coupling, if a LIF “moves to a port that is not expected,” the most direct and common cause is that thebroadcast domain contains ports that do not belong there(or ports that should be in a different broadcast domain/IPspace). When the original port goes down (for example, because you disabled the connected switch), ONTAP looks for eligible failover targets in the LIF’s assigned failover group. If the broadcast domain was defined too broadly or incorrectly, the failover group will also be too broad, and ONTAP may pick a port that appears valid per configuration but is “unexpected” from the design intent.

Option C (“There are no online ports within the same failover group”) would more commonly result inno valid failover target(and therefore an outage) rather than a clean migration to an unexpected port; ONTAP even warns that without a valid target, an outage occurs during failover verification. Option A is too generic and does not specifically explain why adifferentport becomes a valid target. Option D is not a typical ONTAP networking root cause for LIF migration behavior.

Therefore, the behavior is best explained by an incorrectly configured broadcast domain.
