I am running the Linux-based vCenter appliance version 220.127.116.1100 Build 1123965 and am using the embedded database. As of this morning, I can no longer connect to the server with the vi client. The web GUI responds on port 5480 and the "Summary" shows that the "Server" is "stopped". Clicking "start" does not change the Server status.
I logged into the appliance and tried starting the vmware-vpxd service manually and I get a "failed" status. I looked at the vpxd.log file and am receiving the following error:
Failed to connect to database : ODBC error: (08001) - [unixODBC] could not connect to server: Connection refused. (See attached image)
Using the web GUI, I tried the "Test Settings" button on the database page and I receive an error "Incompatible DB schema version" (See attached image)
