This exposure applies to Restoring a server using an incorrect DHCP subnet and gateway, not the direct consequence of Restoring an unmounted iSCSI LUN after initiator ACL change. The actual case-specific risk is: Creating a new filesystem on a temporarily invisible datastore can destroy existing virtual machine disks after access is restored.
