You can use an iSCSI disk for clustered resources, and even for a quorum disk. Using an iSCSI-based quorum and resources is a good way to create a geographically dispersed cluster with Microsoft Cluster Server (creating a GeoCluster is now much easier with the latest version of Microsoft Cluster Server or Veritas Cluster Server). The issue you are seeing is that you still need a lock manager, just as you would for normal Fibre Channel based SAN disks. In other words, without the cluster software, there is no cluster, and corruption may occur.
