Cluster Validation Fails on List iSCSI Host Bus Adapters

I have an 8 Node SQL Failover Cluster.

This cluster has been in service for quite some time now, suddenly the Cluster Validation is failing...

When it gets to the "List iSCSI Host Bus Adapters" (which we do no use on any of these nodes) it fails with the error:
"An error occurred while executing the test. There was an error getting information about the iSCSI controllers installed on the nodes. There was an error retrieving information about the iSCSI host bus adapters from node 'node1'. Invalid class "

The test is not performed on any of the other nodes, it just fails.

This is causing a problem when trying to extend SQL to some of the newer nodes that have been added.

I have tried evicting and readding nodes, I've tried uninstalling/reinstalling failover clustering, among other things.

I did notice that on node7, if I attempt validation, and ONLY mention node7, the test will complete on that box only.

Again, we do not even use iSCSI, this is a Fibre Channel cluster.  It's just the attempt by the validation wizard to list the iSCSI Host Bus Adapters that do not exist, that is failing....

Any thoughts?  I did see a similar post which mentioned having a problem listing Fibre Channel adapters that sounded like the exact same error, but there was no resolution there either...
