DELL OME 2.1 - Duplicated MD storage devices

HI,

I have a huge problem with duplicated MD storage devices in OME. Problem appeared after upgrade from 2.0.1 to 2.1.
After new discovery process the tool is adding the same MD's again. It looks like the problem exist only on MD's which have additional enclosures installed (example MD1200)

On below screen you can see that the same device - with same device name and service tag appears dozens of times, added every 1-2 days

Thanks !
