I’m attempting to upgrade a vSphere 4 to vSphere 5 Enterprise Plus installation. Just a real simple out of the box install. So I run the Vcenter Host Agent Pre-Upgrade Checker. Simple enough. But it fails connecting to the database with a “failed to connect to database for user…” error. and “Look at the log file for more details”
Sigh…. Got me. I know I got my credentials correct. So I do a web search, can’t find anything relevant.
So on a hunch, I just browse the CD and run Autorun with elevated privs (right click, “run as administrator”) and then it worked fine.
