Install Windows Unified Host Utilities
Windows Unified Host Utilities includes an installation program that sets the required Windows registry and HBA parameters so that the Windows host correctly handles the storage system behaviors for NetApp ONTAP and E-Series platforms.
You must have completed the following tasks:
Check the supported configuration in the Interoperability Matrix
Identified any required Windows hotfixes from the Interoperability Matrix
Add the FCP license and start the target service
Verify your cabling
See SAN Configuration for your version of ONTAP or Hardware Cabling for your E-Series storage system on the NetApp Support Site for detailed cabling and configuration information.
You must specify whether to include multipathing support when you install the Windows Unified Host Utilities software package. Choose MPIO if you have more than one path from the Windows host or virtual machine to the storage system. Choose no MPIO only if you are using a single path to the storage system.
The MPIO selection is not available for Windows XP and Windows Vista systems; multipath I/O is not supported on these guest operating systems.
For Hyper-V guests, raw (pass-through) disks do not appear in the guest OS if you choose multipathing support. You can either use raw disks, or you can use MPIO, but you cannot use both in the guest OS.
See Windows Unified Host Installation for detailed information.
Download the appropriate version of the Windows Unified Host Utilities from the NetApp Support Site.
Run the executable file and follow the instructions on the screen.
Reboot the Windows host when prompted.
