Symptoms

This issue occurs if the host bus adapter (HBA) uses an SCSI_DMA64_MINIPORT_64BIT_ONE_4GB_SUPPORTED flag and supports 64-bit addressing in a single 4-gigabyte (GB) region. The BIOS reserves memory in the 0 to 4 GB range in some systems. When this occurs, the Storport driver may provide the HBA with an address space that is less than the full 4-GB region. Therefore, some I/O requests may fail with an insufficient resource status.

Note SAS means Serial Attached SCSI.


Resolution

To resolve this issue, we have released a hotfix. Even though this issue has only been observed in Windows Server 2012 R2 or Windows Server 2012, the hotfix also applies to Windows 8.1, Windows RT 8.1 Windows 8, and Windows RT.

Important Do not install a language pack after you install this hotfix. If you do, the language-specific changes in the hotfix will not be applied, and you will have to reinstall the hotfix. For more information, see Add language packs to Windows.

Windows 8.1 and 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 is 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 0.17xxx

    Windows RT 8.1, Windows 8.1, and 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 8.1 and 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 are not listed, are signed with a Microsoft digital signature.
