Consider the following scenario:
In this scenario, when you select the boot LUN in on the "Where do you want to install Windows?" step of the installation wizard, all paths to the LUN are displayed separately and a message is displayed:
Windows Server 2012 and Windows Server 2008 R2:
"Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information."

Windows Server 2008:
"Windows cannot find a system volume that meets requirements for installation."
Windows is unable to install to a RAW disk with multiple physical paths. If the boot LUN is presented on a single physical path or if the boot LUN has already been initialized prior to installing Windows, Setup will proceed as expected.
There are two methods for working around this behavior.
Method 1: Present the boot LUN on a single path
Configure a single path to the boot LUN when installing Windows. For multiple HBA port configurations, only one HBA port should be connected to the SAN during Windows Setup.
Method 2: Initialize the boot LUN prior to running setup
This method is ideal for scenarios where physically disconnecting the additional SAN connections is not possible or is difficult.
In multiple-path disk configurations Windows Setup does not recognize a disk as bootable until the disk is initialized and the disk signature is present. To initialize the boot LUN and prepare the disk for Windows Setup, you must create a new partition and then delete the newly created partition. Creating a new partition will initialize the disk, write the disk signature, and create a partition. Deleting the partition will remove the newly created partition but leave the disk initialized with the disk signature. It is important to delete the partition so Windows Setup can create both the System Reserved partition and the Operating System Volume. Otherwise, Windows Setup does not create the System Reserved partition.
Detailed steps for Method 2 are as follows:
