prlctl set VMID --device-add hdd does not create hdd image file

According to documentation prlctl set VMID --device-add hdd should create
hdd image file if it does not exist.
However seems it does not work as it described.

Please take look at:

    prlctl set <VM_name> {--device-add hdd | --device-set hdd<N>}
    [--image <file>] [--size <size>] [--iface <ide|scsi|virtio>]
    [--subtype <virtio-scsi|hyperv>] [--position <pos>]
    [--enable|--disable]

    --device-set hdd<N> Modifies the parameters of an existing virtual hard disk.
    Virtual hard disks are named using the hdd<N> format where <N> is the drive index number starting from 0 (e.g., hdd0, hdd1). To obtain the list of disk names, use the prlctl list command with the --info option.

    --image <file>
    Specifies an image file that will be used to emulate the virtual disk.

    If the specified image does not exist, it is created and used to emulate the virtual hard disk.
    If the specified image exists, it is used to emulate the virtual hard disk.

prlctl set VMNAME --device-add hdd --image /home/hdd/VMNAME(.hdd)
Creating hdd1 (+) scsi:1 image='/home/hdd/VMNAME.hdd' subtype=virtio-scsi

VM configuration validation result(s) :
* The image file "/home/hdd/VMNAME" used by hard disk 2 does not exist.Hard disk 2 will not be connected at the virtual machine startup.
Failed to configure the virtual machine.

The instruction is not clear for me.
What I did to resolve this issue:

prlctl set VMNAME --device-add hdd
mv /vz/vmprivate/ID/harddisk1.hdd /home/hdd/
prlctl set VMNAME --device-set hdd1 --image /home/hdd/harddisk1.hdd

This does not work for me with the latest version:
If the specified image does not exist, it is created and used to emulate the virtual hard disk.
