    Here is the relevant code (in HostMO.java):
    
        public List<Pair<ManagedObjectReference, String>> getLocalDatastoreOnHost()
throws Exception {
            List<Pair<ManagedObjectReference, String>> dsList = new ArrayList<Pair<ManagedObjectReference,
String>>();
    
            ObjectContent[] ocs = getDatastorePropertiesOnHyperHost(new String[] {"name",
"summary"});
            if (ocs != null) {
                for (ObjectContent oc : ocs) {
                    DatastoreSummary dsSummary = (DatastoreSummary)VmwareHelper.getPropValue(oc,
"summary");
                    if (dsSummary.isMultipleHostAccess() == false && dsSummary.isAccessible()
&& dsSummary.getType().equalsIgnoreCase("vmfs")) {
                        ManagedObjectReference morDs = oc.getObj();
                        String name = (String)VmwareHelper.getPropValue(oc, "name");
    
                        if (!name.startsWith("-iqn.") && !name.startsWith("_iqn."))
{
                            dsList.add(new Pair<ManagedObjectReference, String>(morDs,
name));
                        }
                    }
                }
            }
            return dsList;
        }

>
> During host discovery, if local storage is enabled for a zone, all VMFS datastores that
are mounted on just one host (i.e. not shared) will be added as local storage is CloudStack.
> When admin adds a VMFS datastore as shared, CS doesn't verify if the storage has already
been added as local storage in the zone. This means the same primary storage is added as different
storages in CS and this leads to failure in operations related to disks because of wrong storage
look ups.
