I'm testing a failover procedure using a mirrored data tier for TFS 2008 with WSS 3.0 on top of SQL Server 2008. I have been following the instructions at http://msdn.microsoft.com/en-us/library/aa980627.aspx but when I got to the "Redirect Web Sites for Team Projects" step I could not connect to Sharepoint Central Administration.
I first got the error "Cannot connect to the configuration database" then after a restart just got 404 errors. I checked the Event Viewer on the app tier and discovered that Windows Sharepoint Services is still pointed to the old database server. It looks like I could use stsadm to change the mapping, but I'm encountering errors I think because I am using named instances.
I'm trying to use this command:
stsadm -o renameserver -oldservername SERVER1 -newservername SERVER2\TFS
And have tried different combinations of specifying the instance name or not without success. I'm still trying to figure out why the TFS guide doesn't mention any of this -- how is Sharepoint supposed to find the new database instance or even run Central Administration if all of the databases have been moved?
