how to create a new hard disk?

[lander7500]

I know to use this task:

• name: Add HardDisk
  vmware_guest:
  hostname: “{{ hostname }}”
  username: “{{ username }}”
  password: “{{ password }}”
  validate_certs: no
  folder: /
  name: “{{vm}}”
  disk:
• size_gb: “{{gb}}”

Create a hard disk, but i doesn’t work. Exist other form?
