One or more fibre channel disks are attached to virtual machine '%1'. Back up programs that use the Hyper-V VSS writer cannot back up volumes that are attached to virtual machines as fibre channel disks. To avoid potential data loss, use another method to back up the data on the fibre channel disks. If you restore the data on this virtual machine, make sure to check the data of the fibre channel disk for integrity. (Virtual machine ID %2)
