Disk Counters on Clustered Disk Record Zero Values

ID: Q189149

The information in this article applies to:

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

SYMPTOMS

When you use Performance Monitor to record activity on a shared clustered drive in a Microsoft Cluster Server, the Physical and Logical Disk counters may record zero or incorrect values. Even after enabling Diskperf -Y and restarting the servers in the cluster, the first server to boot may properly record the disk counters but if the shared drive is failed over to a second server, the disk counters record zero and show no activity on the shared drive on the second server.

RESOLUTION

To work around this problem, you can initiate a failover to the shared disk and then fail back again using the following steps:

Launch Cluster Administrator.

Right-click the group where the shared disk resides, and then click Move Group.

After the disk is online, repeat step 2 and move the group back again. This resets Performance Monitor and allows you to monitor disk activity.

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