Work Around
There are two workarounds for this issue:
1) Run the installation from an elevated command prompt. This is done by clicking
Start, then right-clicking on Command Prompt and selecting "Run as Administrator."
Once presented with a command prompt, you may execute the installation package
by navigating to the directory containing the package and entering it on the
command line.
C:\desktop> msiexec /a <netapp Mpio Pkg>
/a --> to run the installation as Administrator
2) Disable User Access Control. Administrators can do this by going into the
Control Panel, selecting User Accounts, then "Turn User Account Control on or off".
In the next dialog, uncheck the box stating "Use User Access Control (UAC) to help
protect your computer" then click OK.
Please Note :- Modifying the second option requires a reboot
And Of course you must reboot once done with you installation for your NETAPP MPIO to detect your LUNS.
