SYMPTOMS

In Microsoft Windows 2000, a Windows Management Instrumentation (WMI) query may stop responding. This problem may occur when you use WMI to retrieve hard disk drive information. Additionally, the Framework.log file may contain multiple entries with the following information:

Failed to IOCTL_DISK_GET_DRIVE_LAYOUT device DiskID (170) DateTime Thread: ThreadNumber

Note The Framework.log file is located in the %windir%\System32\Wbem\Logs folder.

MORE INFORMATION

The error that the "Symptoms" section describes may also cause lots of SCSI reservation requests. This occurs when a Select * WIN32_DISKDrive WMI query is sent to a cluster node that does not own the disk resource that is being queried. Because the query is issued to a non-owning node, a SCSI reservation request is sent to the logical unit number (LUN) so that the node can mount the volume. However, because the shared disk is reserved by the owning node, the reservation request is rejected. The resulting error condition causes this reservation to be reattempted hundreds of times a second.

The Framework.log file logs the "Failed to IOCTL_DISK_GET_DRIVE_LAYOUT" error every time every time that you use WMI to retrieve hard disk drive information. Therefore, the log grows quickly. After you apply this hotfix, the log file registers the "Failed to IOCTL_DISK_GET_DRIVE_LAYOUT" error only one time for each Select request.

When a "shared nothing" architecture is shared among clusters, we recommend that you do not use WMI to query for drives that the cluster node does not own.

This problem does not occur on versions of Windows that are later than Windows 2000.
