Hi all,
I just had a client where the ESXi hosts are in a different subnet then the vRA and the vCenter. This resulted in the same error: Hmsgroup.onlineSync
After opening up TCP 31031 and 44046 between the ESXi servers on BOTH sides we were able to get it working.
So from what it looks like is that the vRA AGENTS on the ESXI servers are syncing with each other NOT the vRA itself.
The problem with the whole think is that the documentation on all this is very light. The KB 1009562 suggest that yo have to open these ports between the ESXI and the vRA appliance on the REMOTE site, however this dosnt seem true as we just tested this out.
If anyone has an indeep understanding how the vRA rep works in detail (ports etc) please let me know.
regards
D
