Windows Failover Cluster was successfully configured, and the cluster environment was shown in Figure1.
Figure 1 Enabling the WMI service
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.
The problem is related to the S5000T storage device and the UltraPath. We ran a series of comparison tests:
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.
