The Logical Disk Counters Read Zero on a Cluster After a Disk Failover and Failback

The Logical Disk counter values for a shared disk on a cluster may continue to appear as zero in System Monitor after a failover and failback occurs for a disk resource. For example, if you start System Monitor on node A in a cluster (in which disk counters are turned on for all disks) and monitor counters for the Logical Disk object and you then fail over a shared disk from node A to node B, the Logical Disk counter values (for example, Logical Disk\Available MBytes) on node A drop to zero. This is the expected behavior. However, if you then fail over the same shared disk back to node A, the Logical Disk counters remain at zero on node A. This is incorrect.

When you fail over the disk resource back to node A, the Logical Disk counters should resume typical operation on node A to correctly reflect the activity on the disk.
Performance counters are being removed when a disk goes offline (such as when the disk fails over to another computer in a cluster). System Monitor has been modified to check the volume status regularly after a volume goes offline, and to reinstate disk counters promptly when the volume comes back online again.
