Issue

New FAS 70 nodes: node5 and node6 were added to the cluster recently.
There is an issue with their HA interconnect that is impacting failover capabilities:

cluster::*> storage failover show Takeover Node Partner Possible State Description -------------- -------------- -------- ------------------------------------- node1 node2 true Connected to node2 node2 node1 true Connected to node1 node3 node4 true Connected to node4 node4 node3 true Connected to node3 node5 node6 false Waiting for node6, Takeover is not possible: Storage failover interconnect error, NVRAM log not synchronized, Disk inventory not exchanged node6 node5 false Waiting for node5, Takeover is not possible: Storage failover interconnect error, NVRAM log not synchronized, Disk inventory not exchanged 6 entries were displayed.

Although the physical links are up for HA interconnect, the RDMA connections are down:

cluster::*> system ha interconnect status show Node: node5 Link 0 Status: up Link 1 Status: up Is Link 0 Active: true Is Link 1 Active: true IC RDMA Connection: down

Node: node6 Link 0 Status: up Link 1 Status: up Is Link 0 Active: true Is Link 1 Active: true IC RDMA Connection: down
