Consider the following scenario:
- You are running a Windows Server 2008-based computer that
is connected to a storage device over some Microsoft Multipath I/O (MPIO)
paths.
- A Microsoft MPIO Device Specific Module is enabled for
these MPIO paths.
- A heavy load occurs on the storage device.
- One of the MPIO paths fails. Therefore, some logical unit
numbers (LUNs) fail over to another MPIO path.
- You restore the failed MPIO path.
- The computer tries to access the storage device.
In this scenario, disk I/O errors occur. This problem is more
likely to occur when there are many LUNs.
