dellemc_unity_storagepool module not working with pool_id

Hello,

I successfully ran the .py script you posted with Python 3.6. we had issues on Python 2.7 we had to replace from requests import urllib3 from request with import request.

In Summary it seems to be an issue with Python 2.7 and urllib3.

The Ansible Unity product guide says Python 2.7.12 and above are supported.

When you said you have problems with Python 2.7, did you have version 2.7.12, or something different?

Just wondering if I need to ask for a doc change or something like that so others don't run into the same problem you did.

Hello,

I upgraded to Python 3.6 and Ansible 2.9.10 I still get the same error, I also tested on different server (both are running RHEL 7.7)

-bash-4.2$ ansible --version
ansible 2.9.10
  config file = None
  configured module search path = ['/home/user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.6/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.6.8 (default, May  6 2020, 12:04:35) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

Playbook:

Hi Resnik,

The only time that error message should be shown is if the Ansible code is unable to populate anything in a dictionary called "storage_pool_details"

From looking at the output of the SDK call I think that we are tripping up on this code in the ansible module

is_fast_vp_enabled = api_response._get_property_from_raw(
'pool_fast_vp').is_schedule_enabled
details['is_fast_vp_enabled'] = is_fast_vp_enabled

In your SDK output there is no "pool_fast_vp" field.

Two things that you can check.  There should be a dellemc_ansible_provisioning.log file in the same directory as your playbook which may include more details (perhaps an exception trying to get the data above)

You can also try commenting out those three lines in the dellemc_unity_storagepool.py file to bypass the gathering of that info.

Hope that helps
Bryan

Hello, after commenting out dellemc_unity_storagepool.py

#is_fast_vp_enabled = api_response._get_property_from_raw(
#'pool_fast_vp').is_schedule_enabled
#details['is_fast_vp_enabled'] = is_fast_vp_enabled

the playbook ran fine with Python 2.7 and 3.6

thanks
