SYMPTOMS
A cluster node failover does not work when you use SCSI-3-compliant persistent reservations in the Device Specific Module (DSM) component in Microsoft Windows Server 2003 Service Pack 1 (SP1).

Additionally, after you update one cluster node to Microsoft Windows Server 2003 Service Pack 1 (SP1) and then move a disk resource to that node, the Cluster.log file contains the following error messages:

INFO Physical Disk <Disk E:>: [DiskArb]--- DisksOnline ---.

INFO Physical Disk <Disk E:>: [DiskArb] DisksOpenResourceFileHandle: Attaching to disk with signature 944c12e2

INFO Physical Disk <Disk E:>: [DiskArb] DisksOpenResourceFileHandle: Disk unique id present trying new attach

ERR Physical Disk <Disk E:>: [DiskArb] Signature of disk has changed or failed to find disk with id, old signature 0x944c12e2 new signature 0x944c12e2, status 2

ERR Physical Disk <Disk E:>: SCSI: Attach, error attaching to signature 944c12e2, error 2.

ERR Physical Disk <Disk E:>: Online: Unable to attach to signature 944c12e2. Error: 2.

<div class="cause_section">

CAUSE
This problem may occur if the following conditions are true:
 * You are using an array that is SCSI Primary Commands-3 (SPC-3)-compliant.
 * The multipath software maps Microsoft Cluster Service (MSCS) commands to equivalent persistent reservation commands.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
