Table 6.1 provides guidance for troubleshooting issues that may occur when you are installing DPM. This guidance supplements the information in the “Installing DPM” chapter of the DPM 2006 Planning and Deployment Guide (https://go.microsoft.com/fwlink/?LinkId=46357).

Table 6.1   DPM Installation Issues

Issue

Details

Non-DPM applications are interrupted by a DPM installation.

During DPM installation, Setup restarts the Windows Management Instrumentation (WMI) service. If you are running applications other than DPM and its prerequisite software on the DPM computer, you may experience an interruption in the operation of those applications while the WMI service is restarted. To prevent an interruption, shut down all other applications before you run DPM Setup.

You receive error 812 during DPM setup.

Error:

Configuration of reports failed.
 Make sure that Microsoft
 SQL Server Reporting Services is
 installed properly and that it
 is running. ID: 812.

In the DpmSetup.log file, the exception text reads:

The request failed with HTTP
 status 404.

This problem occurs when both SQL Server™ Reporting Services and Windows SharePoint Services are installed in the same Internet Information Services (IIS) application pool.

To resolve this issue, perform one of the following tasks:

  • Uninstall SharePoint Services by using Add or Remove Programs, uninstall DPM, and then install DPM again.

-or-

  • Configure a side-by-side installation of SQL Server Reporting Services and Windows SharePoint Services. For instructions, see “Troubleshooting a Side-by-Side Installation of Reporting Services and Windows SharePoint Services” (https://go.microsoft.com/fwlink/?LinkId=50877).

    Note

    The Rsactivate tool referred to in “Troubleshooting a Side-by-Side Installation of Reporting Services and Windows SharePoint Services” is located in the DPM installation path at Microsoft Data Protection Manager\Prerequisites\MSSQL\Reporting Services\ReportServer\RSReportServer.config.

A disk listed as available in the Add Disks to Storage Pool dialog box is marked as “missing” in the Details pane and the “Disk Missing” alert is displayed.

If you erase or clean a disk that is in the storage pool before reallocating its volumes or removing it from the storage pool, DPM will report that the disk is missing from the storage pool. If you then add the newly erased or cleaned disk to the storage pool, two entries will appear in the storage pool for the same disk.

To avoid this problem, remove disks from the storage pool before erasing or formatting them.

To resolve this problem, use DPM Administrator Console to remove the “missing” disk and add the “outside” disk to the storage pool. Before you remove the “missing” disk, ensure that you have deleted the volumes allocated to the disk that is still listed in the storage pool and that you have reallocated them to another disk.

When you attempt to add the Microsoft Data Protection Manager snap-in to a Microsoft Management Console (MMC) console, you receive the error message:

DPM 2006 Administrator Console cannot load because .NET Framework 1.0 is installed on the system. .NET Framework 1.0 must be uninstalled before the Administrator Console can be loaded.

DPM Administrator Console uses .NET Framework 1.1, which is installed with Windows Server 2003. The issue described here can occur after an MMC snap-in is installed that includes and installs .NET Framework 1.0.

To resolve this problem, in Control Panel, open Add or Remove Programs, and uninstall Microsoft .NET Framework.
