Hi All,
On a newly installed vSAN 6.7 cluster, i'm experiencing intermittent response from the vCenter UI. It would return after ~30-45 seconds, during the UI being unavailable pings are still responsive, ruling out network connectivity. Both vCenter and hosts sit in the same subnet so they do not traverse the firewall for intercommunication.
It's a 3 node Hybrid cluster with the only existing VM deployed being vCenter. Things i've tried are:-
1. Rebooting the vCenter appliance.
2. Running thorough diagnostics at the vendor (Dell R830s) hardware layer on all components, all nodes passed successfully.
3. Migrate the Appliance off to different host servers within the cluster.
4. Have two hosts up at any one time, while shutting off the third (eliminate memory/disk issues). All produced the same issue, regardless of which node was hosting the VM.
Functionality wise, it works however, it is intermittent as described above. Anyone has any ideas/suggestions on this one?
