Did you install the requirements?

[akoscomp]

I ckecked, and yes, I installed the requirements.
I think that ansible request "requests" module on esxi side. But I can't install python modules on the server.

You don't need to. The modules in this collection do not run on vCenter / ESXi directly. They run on the controller and do everything through the vSphere API instead of ssh'ing to vCenter / ESXi and run there.

Could you try delegate_to: localhost:

- name: Example Playbook
  hosts: all
  gather_facts: false
  tasks:
    - name: Gather iSCSI configuration information of ESXi host
      community.vmware.vmware_host_iscsi_info:
        hostname: "{{ vcenter_hostname }}"
        username: "{{ vcenter_username }}"
        password: "{{ vcenter_password }}"
        esxi_hostname: "{{ esxi_hostname }}"
      register: iscsi_info
      delegate_to: localhost

If this doesn't help, maybe this requirement:

community.vmware/requirements.txt

Line 2 in a205c2a

git+https://github.com/vmware/vsphere-automation-sdk-python.git ; python_version >= '2.7' # Python 2.6 is not supported

didn't pull in the requirements of the vSphere Automation SDK for Python automatically and you have to install them manually.

I really wish they would provide a proper PyPI package 😩

delegate_to in not a valid option for this module:
https://docs.ansible.com/ansible/latest/collections/community/vmware/vmware_host_iscsi_info_module.html

I use:

• community.vmware.vmware_host_datastore
• community.vmware.vmware_portgroup
• community.vmware.vmware_vswitch
• community.vmware.vmware_vmkernel
  without any problem, I have problem only with iscsi module.

delegate_to isn't a module option, it tells Ansible where to run the task. Look at the indentation ;-)

I use:

* community.vmware.vmware_host_datastore
* community.vmware.vmware_portgroup
* community.vmware.vmware_vswitch
* community.vmware.vmware_vmkernel

  without any problem, I have problem only with iscsi module.

With or without delegation to localhost?

Thanks, and sorry for ticket. It's my two space bug.
