There are duplicate LUN entries in Windows

[servidores]

Hi I am working with OnCommand System Manager 3.1.3, I am adding some LUNs by FC to Windows but when adding the initiator. It duplicates the disks when I enter the disk manager. I need to know why this is happening.

If you have multiple paths between a storage system and a Windows host computer, you must have some type of MPIO software so that the Windows disk manager sees all of the paths as a single virtual disk.

Multiple paths require MPIO software:

To do this, click Start, click Administrative Tools, and then click Server Manager.

In Server Manager, click Features, and then click Add Features.

Select the Multipath I/O feature for installation, and then click Next. Finish the installation by confirming the selections, and then restart the server.

I was indeed missing the MPIO, thank you very much.
