Resolution

To resolve the issue do the following:

1. Log on to Device Server or Combination Server as root. 
2. Copy the hwfuncs.inc file from the $VOYENCE_HOME/package/juniper/ directory to the $VOYENCE_HOME/custompackage/juniper/ directory. 
3. Check and make sure the file ownership and permissions are the same of root/voyence and 440
4. Edit the $VOYENCE_HOME/custompackage/juniper/hwfuncs.inc file
5. Go down to the getOsVersion() function which starts on or about line 237
6. Replace the following code

                    else{
                                       retVal = sysDescr;
                        }
with 

                                 else {
                                              var<regex> basenameRegex = "JUNOS ([a-zA-Z0-9\\.-]+)*";
                                              basenameRegex = sysDescr;
                                              if (basenameRegex.match)
                                                   { retVal = basenameRegex[1]; }
                                      }
.

7. Save and exit the hwfuncs.inc file
8. Restart services by running "service voyence restart"
9. Execute Pull system properties on the device.
