Taking a snapshot with Microsoft Windows Server 2012 Virtual HBA

The provider automatically attaches the LUN to the guest OS through a virtual port.

During the snapshot-creation process, the IBM® Storage Support for Microsoft VSS and VDS maps the snapshot target LUN to both the physical HBA WWPNs and virtual WWPNs. The LUN is then assigned to the VM from the VMware ESX(i) Server as the pRDM disk.
