  • ONTAP 9

Issue

  • After a controller head swap and ONTAP upgrade, the NetApp System Alert Monitoring (SAM) report flagged a medium-risk best practice violation:

“Cluster port is home to more than one cluster LIF.”

  • In the affected cluster, both cluster LIFs (Logical Interfaces) on each node were configured with e1a as their home port, despite the presence of two cluster-capable ports (e1a and e7a) per node.

Relevant log output:

Cluster
    netapp-01_clus1 up/up 169.254.177.66/16 netapp-01 e1a true
    netapp-01_clus2 up/up 169.254.177.70/16 netapp-01 e1a true
    netapp-02_clus1 up/up 169.254.196.112/16 netapp-02 e1a true
    netapp-02_clus2 up/up 169.254.177.80/16 netapp-02 e1a true

  • Potential impact: degraded cluster performance and loss of redundancy.
