DPM not detecting library drives RRS feed

  • Question

  • I'm running DPM 2010 with March hotfix on Windows Server 2008 R2 SP1 with an Overland REO 4500 virtual tape library.  I've been running DPM 2010 with this VTL on Windows Server 2008 R2 for a year with no problems what so ever.  I recently rebuilt the server from scratch on Windows Server 2008 R2 SP1 and now DPM can't see the drives in my VTL.  The VTL and 16 HP LTO-2 drives are visible in Device Manager, but DPM can only see the library and no drives.  I've run the DPMDriveMappingTool and verified its output as being correct and run a rescan from the DPM management console, but the drives still won't show.  I've downloaded HP tape tools and this tool can see all 16 drives and shows they are functioning correctly.  How can I troubleshoot this issue further to get DPM to see the drives?

    Thanks
