Issue Resolution/workaround
Running Test-Cluster fails with network communication
errors.
With USB NIC enabled in iDRAC, if you run the Test-Cluster
command to verify the cluster creation readiness or cluster health,
the validation report includes an error indicating that the IPv4
addresses assigned to the host operating system USB NIC cannot
be used to communicate with the other cluster networks.
This error can be safely ignored. To avoid the error, temporarily
disable the USB NIC (labeled as Ethernet, by default) before
running the Test-Cluster command.
The USB NIC network appears as a partitioned cluster network.
When the USB NIC is enabled in iDRAC, cluster networks in the
failover cluster manager show the networks associated with the
USB NIC as partitioned. This issue occurs because the cluster
communication is enabled by default on all network adapters, and
USB NIC IPv4 addresses cannot be used to communicate
externally, which, therefore, breaks cluster communication on
those NICs.
Remove the USB NIC from any cluster communication by using
the following script:
$rndisAdapter = Get-NetAdapter -
InterfaceDescription 'Remote NDIS
Compatible Device' -ErrorAction
SilentlyContinue
if ($rndisAdapter)
{
Write-Log -Message 'Remote NDIS
found on the system. Cluster communication
will be disabled on this adapter.'
# Get the network adapter and
associated cluster network
$adapterId =
[Regex]::Matches($rndisAdapter.InstanceID,
'(?<={)(.*?)(?=})').Value
$usbNICInterface = (Get-
ClusterNetworkInterface).Where({$_.adapterId
-eq $adapterId})
$usbNICClusterNetwork =
$usbNICInterface.Network
# Disable Cluster communication on
the identified cluster network
(Get-ClusterNetwork -Name
$usbNICClusterNetwork.ToString()).Role = 0
}
