Fiber System Loses SCSI Reservation After Multiple Restarts

• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Cluster Server
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

A potential problem exists after multiple reboots of a clustered system using a fiber channel array as the shared storage system. After multiple restarts, the SCSI reservations may lose a drive array because of repeated SCSI resets.

CAUSE

This problem is because a reservation conflict occurs in the Disk.sys driver.

RESOLUTION

A new file entry solves the problem by enumerating the following information in Disk.sys STATUS_DEVICE_BUSY (the status that indicates a reservation conflict).

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
