Disk paging error 51 on hyper-V when windows server backup runs RRS feed

  • Question

  • I am getting multiple errors on 2 of my Hyper-V servers running 2008 R2.

    An error was detected on device \Device\Harddisk2\DR110 during a paging operation.

    Sometimes it references DR116 or DR119 or DR110 or DR16 etc.

    I have tried the updates on this post http://social.technet.microsoft.com/Forums/en/windowsbackup/thread/c76a237b-bbf8-4127-9e89-e292d7d913ed  KB975354 and KB975354-v2

    But still get the errors after a reboot.

     Am I right in thinking DR stands for device removeable?

    Are these disks actually VHDs?

    The backup seems to complete OK. Thease errors only ever occur just after the backup kicks off.

    Cheers in advance for any help!

  • Can anyone confirm id the DR stands for device removeable? I'm wondering if Hyper-V refers to it's VHDs as this.

  • We are also receiving these messages. I believe they are referencing the Hyper-V VHDs but, like you, am uncertain.
