Symptoms

Consider the following scenario:

  • You have a multiple-node failover cluster that is running Windows Server 2012.

  • You create a cluster file share on the cluster.

  • You connect to the share from a Windows 8-based or Windows Server 2012-based client computer.

  • You transfer a file to or from the share.

  • During the file transfer, you disconnect the cable that connects the drive to the cluster.

  • You receive an error message that resembles the following on the client computer:

    STATUS_DEVICE_NOT_CONNECTED

In this scenario, the Server Message Block (SMB) 3.0 Transparent Failover feature does not work, and the file transfer fails.

Note The expected behavior is that the client computer reconnects to another cluster node to continue the file transfer after you disconnect the drive cable.

Cause

This issue occurs because the SMB 3.0 driver does not handle the "STATUS_DEVICE_NOT_CONNECTED" error correctly.

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC).

Windows Server 2012 file information notesImportant Windows 8 hotfixes and Windows Server 2012 hotfixes are included in the same packages. However, only "Windows 8" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8" 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

    6.2.920 0.16 xxx

    Windows Server 2012

    RTM

    GDR

    6.2.920 0.20 xxx

    Windows Server 2012

    RTM

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • 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" section. MUM and 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.
