I have a 4 node 2019 cluster, subnet is 192.168.12.0/24. I'm moving the hosts and cluster to a new subnet 192.168.19.0/24.
I have already moved the hosts IP and everything is running fine, except in the cluster Server name, when I try to change the IP Address, the network dropdown doesn't show the new subnet.
In Failover cluster manager, under networks, the Host LAN shows both subnets and the cluster use is both Cluster and Client.
I tried adding another 'IP Address' but again, the new subnet doesn't show up in the dropdown.
How can I have the new subnet show up in the dropdown?
Properties of the IP Address showing a single subnet in the dropdown:
Network property of the Host Network showing the additional subnet:
How can I get the subnet added to the IP Address property so I can bring that resource online again?
Thanks.
