Microsoft DPM 2007 and DPM 2010 - Exchange Storage Group Replica inconsistent

posted 12 Jun 2011, 04:23 by Tristan Self

After a very painful DPM 2007 to DPM 2010 upgrade and a migration from Windows 2003 Server to Windows 2008 Server I was left with this problem when trying to bring my Exchange database replicas consistent again. Every time I tried I got the following error, I destroyed and recreated the stores recreated the replicas but still the same error, it was getting to the point of having to pull the whole lot. Then I fixed the problem as shown below:

PROBLEM:
The replica of Storage group SG1 on oaksmfmail01.oaklands.ac.uk is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent.

For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106)

Data consistency verification check failed for LOGS of Storage group SG1 on oaksmfmail01.oaklands.ac.uk. (ID 30146 Details: Unknown error (0xfffffc01) (0xFFFFFC01))

SITUTATION:

I was using the 32-bit ese.dll and eseutil.exe from our Windows 2003 Server (32-bit) Exchange 2003 (32-bit) install running on a Windows 2008 (64-bit) Server with DPM 2010 (64-bit)

CAUSE:

The replica was being created ok, but when the stores were verified by using the ese.dll and eseutil.exe i'd copied from the Exchange server they choked and were marked as inconsistent.

SOLUTION:

I found this article, the excerpt i've taken from it is below:

http://blogs.technet.com/b/askcore/archive/2008/06/12/data-protection-manager-2007-important-information-for-using-eseutil-when-configuring-exchange-server-protection.aspx

Lastly, if you’ve installed DPM 2007 on a Windows Server 2008 operating system, and you are protecting Exchange Server 2003 on a Windows Server 2003 computer, you must install the Exchange Server 2007 version of the eseutil.exe and ese.dll files.

You can download this version from http://go.microsoft.com/fwlink/?LinkId=112325 Microsoft Exchange Server 2007 Management Tools

Basically I had copied the Exchange 2003 (32-bit) ESE.dll and eseutil.exe files from my Exchange 2003 server as that what you should do right?

Well for Windows 2008 Server (64-bit) and DPM2007/2010 (64-bit) you need the Ese.dll and eseutil.exe from Exchange 2007 (64-bit) instead.

So i stuck in the Exchange 2007 DVD and copied these files off in into my DPM/bin directory, started it all going again and volia, consitstent stores!
