Scenario : Installed DPM 2010 on a Hyper-V 2008 Server R2 SP1.
The server name of this Hyper-V is B34.systemcenter.com
However when trying to create a protection group to protect the Hyper-V VM, it gives the error message (ID : 31313). The server is already patched with the KB975354 as required by the error message. Very weird !! First time happening to me.
So after looking around found something that just works.
I launch the Microsoft SQL Server Management Studio (select the DPMDB database) and then key in the following in the New Query
Just replace the server name in the pink in colour with the correct server name (FQDN). Execute it
The output as below :
After that I was able to create the protection group to Protect the VMs. As I mentioned, it’s weird, very weird. It doesn’t happen to my previous installations before.
Thank you and hope this helps you as it helps me.
