Consider the following scenario:
- You connect a Windows Server 2008 failover cluster node to an external storage device.
- You use Microsoft Multipath I/O (MPIO) to manage the storage device.
- The storage device is part of the cluster resources.
- All MPIO paths to the storage device fail, and then the paths recover after awhile. For example, you turn off the storage device, and then you turn it back on after awhile.
