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
This is a known issue in OME version 2.1. You can call Dell Tech Support (800-945-3355) and they will be able to help you to get over with this issue.
If it is a known issue why it is not documented? Last time when I called them they told me i should contact different number because the MD's are not stored in US, the second number told be that they do not support dell ome request and provide me third number... the last on finally called me but they were not able to understand dell ome related problem,
