Install MPIO on Windows Server 2008 R2
MPIO is an optional feature in Windows Server 2008 R2, and is not installed by default.
Install MPIO on Server Core installations of Windows Server 2008 R2
Because the Server Core installation of Windows Server 2008 R2 does not include the Server Manager interface, you must install MPIO by using a command prompt. Until you enable MPIO by using the DISM tool, you cannot use the mpclaim command.
Open a command prompt to run the following commands. After typing a command, press ENTER.
Enable MPIO:
Dism /online /enable-feature:MultipathIo
