Adding volume pair to a remote copy group

[Mathieu3387]

While trying to add a volume pair to a remote copy group with the state "add_volume", the request seems to be unresponsive.

Playbook:

• name: Add volume to remote copy group
  hpe3par_remote_copy:
  storage_system_ip: "{{ storage_system_ip }}"
  storage_system_username: "{{ storage_system_username }}"
  storage_system_password: "{{ storage_system_password }}"
  state: add_volume
  remote_copy_group_name: {{ rcg_name }}
  volume_name: "{{ volume_name }}"
  admit_volume_targets:
  • target_name: {{ 3par_target }}
    sec_volume_name: "{{ secondary_volume_name }}"

This issue occurs even if the RCG is newly created previously on this playbook, or was already created and wether his state stopped or started.

Trying to run API request from Postman give me the same result, nothing happens.
