During install, one or more systems have a problem assigning the correct interface name. for example, idrac shows interface ens2f0 on slot 1 port 1  whereas on the system, it shows ens2f0 as slot1 port 1 via mac address. The system with the different interface assingment casnnot join the cluster and eventually becomes unreachable (looses it's ip address)
    

OPC 4.18.4, rehl 4.9
    

The cluster installation fails fails at least 9 out of 10 times
    

    1. ipi install initiated
    2. bootstrap initially online
    3. installation fails
    

successful ocp install

    

Customer has installed the same configuration on other systems without problems
This is the first install will Dell AMD servers. 
The interface assignment for the servers is not predicable/consistent. 
Customer tried initially with bonds but then removed the bonds to simplify the situation and ranintothe same problem

It is trying to rename some network interfaces reusing the existing names (ens2f* and ens5f*). This seems to match the issue description for https://access.redhat.com/solutions/7112603 and https://issues.redhat.com/browse/RHEL-44630 . From the Jira issue, I can see the lspci output ("sos_commands/pci/lspci_-tv" in the sosreport) shows the same structure with two cards hanging from the same IOMMU root complex:
