The database server that was storing the vCenter database had an issue and I was forced to move the database to another database server (SQL Server). I did a backup and restore using SQL Server.
vCenter will connect fine and loads up, but there are 3 hosts that I just recently (last week) upgraded to v5 from v4, and after I moved the database vCenter will not communicate with them, even to disconnect them. I see an error in the yellow "alert box" that tells me it's a bad user name and password, which I understand is the internal vmware password, not root.
My question is, how can I get the hosts disconnected so I can reconnect and redo the password, without having to power off the host and take all the VMs on it down with it. Yes they will start up on other hosts, but there is still a downtime and I'll get complained at. The other hosts that I have not upgraded are working fine, just the ones I recently upgraded are having the problem.
And yes, before this database problem I was able to disconnect, reconnect, whatever. Now I can't even put them in maintenance mode. I tried restarting the management network, but that doesn't help.
