Ошибка подключения на адресе службы HACMP

У меня установлен Ansible 2.6.20 на Oracle Linux 6.10 с Python 2.6.6, и я пытаюсь настроить машины IBM с AIX 7.2 с Python 2.7.15 в кластере HACMP.

Запуск ansible в консольном режиме или ansible-playbook на выделенном узле работает нормально, но если я попытаюсь запустить с IP-адресом службы кластера, я получу ошибку целевой недоступности.

                          +--------> node A   10.1.1.11             => connection o.k.
                         /       
Ansible host 10.1.2.10  -----------> cluster service ip 10.1.1.10   => connection failure
                        \        
                         +--------> node B   10.1.1.12              => connection o.k.

Вот сообщение об ошибке Ansible (отформатированное) с замененным имена пользователей и серверов в целях безопасности.

SSH-соединение Manuell с аутентификацией с открытым ключом отлично работает со всеми тремя IP-адресами.

У меня следующие вопросы:

• Кто-нибудь знаком с этой проблемой и знает ли ее решение .
• Что я могу сделать, чтобы получить больше результатов отладки?
