hdarray Unix agent plugin not graphing results

The hdarray unix-agent script,rrd, or discovery is not working properly.
The state in health/metric=state/ is showing as fail even when the Drive and controller status is Listed as 'Ok'

When the graphs are generated the 'Value', 'High Limit' and 'Low Limit' are all zero even when the data provided by the unix agent varies between 0 and 1.
