Hello,
i migrated all databases from a SQL Server 2008r2 Cluster (Name: Cluster01) to a SQL Server 2012 Cluster (Name: Cluster08). After the migration I renamed the 2008r2 Cluster to ClusterOL and the 2012 Cluster to Cluster01. So I dont have to configure the applications that uses the old 2008r2 Cluster.
Since then the Maintenance Plans dont work anymore and even so the database mail. The event-entrys say that the local server instance could not be found. Network Error 26. Clients can connect the server and find their databases without problem.
So I check different things:
sp_helpserver = cluster01
Select @@servername = Cluster08
so i executed:
sp_dropserver 'cluster08', null = The server cannot be found.
sp_addserver 'cluster01', local = the server already exists.
Well then even when I try to add a server with the old name, so eventually i can delete it then:
sp_addserver 'cluster08',local = server already exists (mention sp_dropserver says it doesnt exist).
In the registry under NKLM\Software\Microsoft\MSSQLServer\Cluster\clustername is the old name Cluster08.
I already tested the renaming process of the 2012 cluster before without problems, but with names that didnt exists in our network before. Only the production renaming shows this behaviour:(
I dont know how to correct this, so that database mail and mps are working again. renaming the cluster again to cluster04 and back to cluster01?
Any ideas plz?
