yesterday I updated our OnCommand Unified Manager from 6.3RC1 to 6.4P2 and then 7.0 and connected a Performance Manager with it (full integration).
It all worked fine for several hours, but in the evening the Cluster Dashboard was empty. The Clusters are correctly shown and monitored when you go into Health or Performance.
When I try to add a Cluster again, I get an error message, that the Cluster already exists (which is correct, but it is not shown in the dashboard).
I made a snapshot before upgrading, so I could go back to 6.3RC1 of course, but I want to stay with 7.0 if this is not a major error which can't be fixed.
