Hi @Sue_8827 ,
As the error message said, the virtual IP of the cluster should be unique, please check your virtual IP address, if the IP address is duplicated, you can consider changing the IP address, right-click the IP address, choose Properties, you can see the Static IP address and change it to make sure this new IP is unique on the network, if you change any of the settings, try to bring the resource online first
