Installation on 2012 R2 and MSCS very slow

[Ganimede-Dignan]

Hi,

I'm try to install a new system from an R3load export of our productive ECC into a new MSCS based on Windows 2012 R2. Our ERP is 6.05 SP16 with Kernel 7.21 SP 300.

The installing, first node... into input session is very slow, several hours from start to this point there are 12 hours...

Have you got any idea?

Thank you so much.

Hi

the problem is related to the new functionality of continous availability for SMB 3.0 Shares in Windows Server 2012 Failover Clusters.

It is known problem.

The fix is documented in SAP Note 1823833 or Microsoft KBA 2820470.

The problem not only shows up when accessing non existing shares, it is also shows up if you retrieve file attributes relative to the root directory of a share (for \\host\share\., or \\host\share\..). This operations are not allowed and will return error messages which are normally handled very well be applications. But the error message will be fired by the API 60 seconds after the call...

So it is a very good idea to implement above KBA (Windows Server 2012: install the fix, Windows Server 2012 R2: set the registry key).

I recommend to set this Reg-Key on all Windows Server 2012 FF versions.

regards

Peter

PS: by the way. The Prerequisit Checker Phase in the installation should check whether the Reg-Key is set...
