Some Cluster Disks Are Not Available After Installing SP6

ID: Q251007

The information in this article applies to:

Microsoft Cluster Server, version 1.0

SYMPTOMS

After you apply Microsoft Windows NT 4.0 Service Pack 6 (SP6), some cluster disks may not come online. If the quorum disk is affected, the entire cluster does not start. The problem is most likely to occur after you "cold boot" the computer. If cluster logging is enabled, you may see an entry similar to:

Physical Disk Disk X: : SCSI, error reserving disk, error 21.

CAUSE

The partition table on the disk contains an invalid entry that is misinterpreted by the cluster disk driver.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.
