VSphere connection issue

Posted on 2014-12-12
Last Modified: 2014-12-30
Recently (Last two months) upgraded out vSphere server to 5.5.  Perodically, I would see a problem connecting using the vSphere client.  Now every time I try to connect I get this message.

VSphere Client could not connect to "192.168.x.x". An unknown connection error occurred.  (The request failed because of a connection failure. (Unable to connect to the remote server))

I can ping the server and I get this message whether I am using the client on this server or from a client on a different server.

Check that the vCenter services are running on the server.

Also check if you are using SQL Server Express Edition, the database has not grown larger than 10GB

Thanks to both.  I do see that the Database size is very close to the express limits.  Is there a clean way to migrate from SQL Server Express to a full version of SQL.  Maybe a published walk through or tutorial?  Is it just a matter of installing a new instance of SQL, backing up and restoring to the new instance?

If SQL Express DB near 10GB this is the reason.

SQL Express is not really suitable anymore, for four hosts or more, and their VMs, vCenter 5.5 is very noisy, compared to older versions.

Would it be simpler to just uninstall the vCenter Server and install a new instance using a full SQL version??

Full SQL and Re-install, yes if you are not a SQL DB Admin!
