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, click the following article number to view the article in the Microsoft Knowledge Base:
