Additional info:
From Customer:
I increased the memory to 16GB and restarted the Server.  I also did restart of the evmserverd. The first time the system online,  CFME was in a rather hung state.  I had to restart the server a second time and everything came back fine.   I waited awhile for the provider worker to finish the discovery.  Still no Storage.

Yes,  This was upgraded from CF 4.2.  Server was orginally installed around March 2017 at 4.2.  Upgraded to 4.5 last month.
