I’ve listed high-level steps below. For the details, refer to the product guide at

https://github.com/dell/ansible-isilon/blob/dellemc_ansible/docs/Ansible%20for%20Dell%20EMC%20Isilon%20v1.1%20Product%20Guide.pdf

The following example is using CenoOS 8 + python 3.6 + Ansible 2.9.5 + Isilon sdk 8.1.1 + OneFS 8.2.2. The overall steps are as the followings:

  1. Install Ansible 2.9.5

# dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

# dnf install ansible

  1. Check the python version for ansible by using the following command

# ansible –version

In my case it’s python 3.6.8

[root@c8 ~]# ansible –version

ansible 2.9.5

  config file = /etc/ansible/ansible.cfg

  configured module search path = [‘/root/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’]

  ansible python module location = /usr/lib/python3.6/site-packages/ansible

  executable location = /usr/bin/ansible

  python version = 3.6.8 (default, Nov 21 2019, 19:31:34) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]

  1. Install Isilon sdk 8.1.1

# pip3 install isi_sdk_8_1_1

  1. Install Isilon Ansible module: (make sure the path is aligned with the python version)

Copy utils/dellemc_ansible_utils.py to  /usr/lib/python3.6/site-packages/ansible/module_utils/

Copy all module Python files from ‘isilon/library’ folder to  /usr/lib/python3.6/site-packages/ansible/modules/storage/emc

  1. Install the playbook

Coyp dellemc_ansible/isilon/playbooks to any place you want

  1. Test the installation

Update the playbooks/ flo_test.yml. mine is as below:

– name: Collect set of facts in Isilon

  hosts: localhost

  connection: local

  vars:

    onefs_host: ‘192.168.116.88’

    verify_ssl: False

    api_user: ‘root’

    api_password: ‘a’

    access_zone: ‘System’

  tasks:

  – name: Get nodes of the Isilon cluster

    dellemc_isilon_gatherfacts:

      onefs_host: “{{onefs_host}}”

      verify_ssl: “{{verify_ssl}}”

      api_user: “{{api_user}}”

      api_password: “{{api_password}}”

      gather_subset:

        – nodes

    register: subset_result

  – debug:

      var: subset_result

run the playbook:

ansible-playbook  <path to playbooks/flo_test.yml>

If everything is good, you should see the Info for your Isilon is returned:
