Applies to
- Controller upgrade
    
- AFF8060 to AFF A700
 
 - ONTAP 9.7P6
 - Cisco Nexus 3132 Cluster Network Switches
 
Issue
- After completing controller upgrade from AFF8060 to AFF A700 the new shows not healthy
 
cluster::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
node01                false   true
node02                true    true
node03                true    true
node04                true    true
 
- Cluster applications fail to come online on the new controller
 
cluster::> storage failover show
                              Takeover
Node           Partner        Possible State Description
-------------- -------------- -------- -------------------------------------
node01         -              false    Waiting for partner. Waiting for
                                       cluster applications to come online
                                       on the local node. Offline
                                       applications: mgmt, vldb, vifmgr,
                                       bcomd, crs, scsi blade, clam.
                                       Takeover is not possible: Storage
                                       failover is disabled
node02         node01         false    Waiting for node01, Takeover is
                                       not possible: Storage failover is
                                       disabled
node03         node04         true     Connected to node04
node04         node03         true     Connected to node03
 
- Connecting directly to the node management LIF of the replaced node shows all nodes in the cluster unhealthy
 
cluster::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
node01                false   true
node02                false   true
node03                false   true
node04                false   true
- Migrating all cluster LIFs over a single switch brings the node healthy again
