NBU 7.6 for VMware and transport mode SAN

Hi

This is my enviroment:

Master / Media server on the same host: Windows 2012 R2 physical server with FC dual port connected to a two fabric SAN Brocade 6505.

vCenter 5.1 on a virtual machine Windows 2012 R2.

Backup virtual machines from 15 ESXi 5.1 host.

I want to use SAN transport mode. I find that the only method is configure FC zoning to let's NBU media server access to VMFS-5 formated LUNS by ESXi host. Then, from windows disk administrator console, I found these LUNS and appears like the image I attach to this post.

I'm afraidif someonedecidesmistakenly putonlinethedisk andreformat toNTFS.

Is there anyway to prevent thisproblem?

My configuration method is correct? Now, I can backup my virtual machines faster than NBD tranport mode, but I needto truston these settings to aboid problems.
