datasource enumeration problem RRS feed

  • Question

  • When modifying a protection group I want to add BMR/SystemState protection for a server. I click the plus button next to the server name to list resources that can be protected. A moment later, popup window appears that states "DPM is unable to enumerate contents in \\?\Volume{d2c9f317-6a26-11df-b968-806e6f6e6963}\ on the protected computer <computer_name>. Recycle Bin, System Volume Information, non-NTFS volumes, DFS links, CDs, Quorum Disk (for cluster) and other removable media cannot be" (note that the message is truncated - is there any way to display the whole message?)

    The main problem is that there's no such volume on the protected server. For completeness sake, here's volume enumeration on the protected server:

     

    C:\Users\administrator> vssadmin list volumes

    vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool

    (C) Copyright 2001-2005 Microsoft Corp.

    Volume path: \\?\Volume{d2c9f2f0-6a26-11df-b698-806e6f6e6963}\

        Volume name: \\?\Volume{d2c9f2f0-6a26-11df-b698-806e6f6e6963}\

    Volume path: D:\

        Volume name: \\?\Volume{0b47a611-6c88-11df-90ae-0022196cc2c2}\

    Volume path: \\?\Volume{3ff7c6b1-c696-11df-9f2d-0022196cc2c2}\

        Volume name: \\?\Volume{3ff7c6b1-c696-11df-9f2d-0022196cc2c2}\

    Volume path: C:\

        Volume name: \\?\Volume{d2c9f2f1-6a26-11df-b698-806e6f6e6963}\

    Volume path: E:\

        Volume name: \\?\Volume{75b3d3ef-6a33-11df-a591-0022196cc2c2}\

    Volume path: F:\

        Volume name: \\?\Volume{0b47a618-6c88-11df-90ae-0022196cc2c2}\

     

     

    Notice the similarity between the volume reported by DPM and the first volume in the vssadmin list volumes output - they're very similar, but not same. Btw. that first volume is the System reserved 100MB partition.

    Note: the second volume in the the output without a drive letter is unused disk partition without an assigned drive letter.

    Note2: I can select BMR/SystemState once I dismiss the message

    Can anyone explain this?

  • H,

    you always get this message when DPM cannot enumerate all for soem reason.

    You can ignore this for as long as you can select the intended data source for protection like in your case.

  • Thanks Ruud for the response, although I must say your answer is not too satisfactory.

    Can one determine what is that "some reason"? This way it looks like there's either some misconfiguration or a problem on the target computer or it's a problem on the DPM side.

    Furthermore, DPM complaining about (at least it looks like this way) non-existing volumes doesn't give me much confidence that everything is alright.
