Windows Failover Cluster was successfully configured, and the cluster environment was shown in Figure1.
 

Figure 1 Enabling the WMI service

  • Application server operating system: Windows Server 2008 x64


 

We used a LUN mapped from the storage device to configure two file services under node 1 and node 2. We created file folders on node 1 and node 2 and shared them for external access. We used a 15 GB LUN that was owned by controller A and was mapped to node 1 to create logical partitions and formatted it as an NTFS file system. We used a 15 GB LUN that was owned by controller B and was mapped to node 2 to create logical partitions and formatted it as an NTFS file system.

We copied large files from a local Windows 7 PC to the shared file folders on node 1 and node 2. The copy progress halted after a few minutes. We checked on the storage device and found out that there was no I/O.

 

Alarm Information
None
Handling Process
Reinstall the operating system of the specific client. Or use another proper client to copy files to the cluster.
Root Cause

The problem is related to the S5000T storage device and the UltraPath. We ran a series of comparison tests:

  • We uninstalled the UltraPath from the cluster node and performed the same testing procedure. The copy progress halted again.
  • The copy progress halted when we were copying large files from a Windows 7 PC to the shared file folder on the cluster.
  • We performed the copy operation again, and the new copy progress halted too.
  • We performed the same operation on two Windows XP PCs, and no such problem occurred.
  • We performed the same operation on another Windows 7 PC, and no such problem occurred.
  • We restarted the host and the storage device and performed the same operation on the original Windows 7 PC five times, and the same problem occurred each time.
  • We restarted the host and the storage device and performed the same operation on another Windows 7 PC five times, and no such problem occurred.

Due to the complexities of the environment on the original Windows 7 PC, no direct cause was found.
Conclusion: This problem was caused by the specific Window 7 client, and had nothing to do with the UltraPath, cluster, or storage device environment.

Suggestions
Reinstall the operating system of the specific client, or use another proper client to copy files to the cluster.
