Symptoms

Assume that you install the Hyper-V role in Windows Server 2012 R2 or Windows Server 2012. In this situation, you may encounter one of the following issues:

Issue 1

Hyper-V storage migration fails when you try to migrate virtual hard disk (VHD) and configuration files to Cluster Shared Volumes (CSV) volumes in Windows Server 2012 R2. When this issue occurs, you receive an error message that looks something like this:


Migration did not succeed. Not enough disk space at '\'.


Note This issue also occurs, and has been fixed in Windows Server 2012. For detailed information, see hotfix 2913461.

Issue 2

Hyper-V replication stops with an ERROR_BAD_COMMAND error in Windows Server 2012 R2 or Windows Server 2012. The Hyper-V primary server treats this as an unrecoverable error. Therefore, the Hyper-V replication (HVR) enters a suspended state unexpectedly, and never sends delta again.

Note Only a manual restart of the replication could restore it.

Cause

Issue 1

This issue occurs because the target CSV volumes are incorrectly identified as being a system drive volume instead of multiple separate CSV volumes.

Issue 2


This issue occurs because the exclusive write lock for virtual hard disks (.vhd or .vhdx files) can't be obtained. Then, the VHD Miniport (VHDMP) driver indeed returns a STATUS_LOCK_NOT_GRANTED (C0000055) error. However, it's overridden by the STATUS_INVALID_DEVICE_STATE/ERROR_BAD_COMMAND error from another call to VHDMP.

Windows Server 2012 R2 file information and notes

Important Windows 8.1 hotfixes and Windows Server 2012 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's listed under "Windows 8.1/Windows Server 2012 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:

    Version

    Product

    Milestone

    Service branch

    6.3.960 0.17 xxx

    Windows Server 2012 R2

    RTM

    GDR

    6.3.960 0.18xxx

    Windows Server 2012 R2

    RTM

    GDR

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2012 R2" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes aren't listed, are signed with a Microsoft digital signature.
