Symptoms

the following scenario:
  • You use a cluster shared volume on a Windows Server 2008 R2-based failover cluster that has the Hyper-V 2.0 role installed.
  • You register a logical unit number (LUN) from the host operating system on the cluster shared volume.
  • The Disk Control Manager component detects a STATUS_CONNECTION_DISCONNECTED error and starts a failover.
In this situation, Windows Server 2008 R2 does not detect the LUN.

Cause

This issue occurs because the Disk Control Manager component does not remap the cluster shared volume resource after a failover occurs.

Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.1.760 0.17xxxWindows Server 2008 R2RTMGDR
    6.1.760 0.21xxxWindows Server 2008 R2RTMLDR
    6.1.760 1.18xxxWindows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
