Server may freeze during startup when ALUA-capable storage is used in Windows Server 2012 R2 or Windows Server 2012


View products that this article applies to.

Symptoms

Assume that you have a storage configured to have multiple paths to an Asymmetric Logical Unit Access (ALUA)–capable storage array, and some of those paths are in a Standby state. This issue occurs when the first discovered path for a disk device is a Standby path, and the storage array responds to the host on this path with an error that is defined in the SCSI Primary Commands (SPC) specification.

Note Windows Server 2008 R2 also exhibits the behavior that is described in this article.

Workaround

To work around, change the state of the first connected path for a disk device from Standby to Active, or disconnect the path.

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:

    VersionProductMilestoneService branch
    6.3.960 0.17 xxxWindows Server 2012 R2RTMGDR
  • 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" 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.
