A cluster IP address shows as "Failed" during precheck. This precheck tests that all IPv4 addresses and DNS network names are online and reachable. For example, a failed IPv4 or network name can cause this test to fail.
To resolve this, perform the following steps:
Run the following command:
Get-ClusterGroup -name "Cluster Group" | Get-ClusterResource
Ensure that all network names and IP addresses are in an online state.
Run the following two commands:
Stop-ClusterResource -name "Cluster IP Address x.x.x.x"
and then
Start-ClusterResource -name "Cluster IP Address x.x.x.x"
