[BUG]: powerstore.host cannot manage state

[jason-technology]

Describe the bug
powerstore.host works fine to create hosts. If the playbook is run a second time to confirm / validate state, it errors out that the port name is already in use.

To Reproduce
Steps to reproduce the behavior:

1. Step 1 run playbook to configure a new host
2. Step 2 run playbook again to verify state
3. Step 3 observe error
   ...
   n. Step n See error

Expected behavior
I expect that if the host exists as described that the module would return "OK" rather than error out.

Screenshots
If applicable, add screenshots to help explain your problem.

Logs
If applicable, submit logs or stack traces from the affected services

System Information (please complete the following information):

• OS/Version: Ubuntu 20
• Ansible Version 2.13
• Python Version 3.8.10
• Powerstore SDK and Galaxy Collection: Latest

Additional context
Actual Error:
Bad request: One of ther provided poret names is already registered with another host

Hi @jason-technology ,

I tried to reproduce the issue and idempotency seems to work for the ports registered to the host, the error seems to be displayed only when the port is already registered to a different host. Could you please share the playbook and the log trace from ansible_powerstore.log, generated in same location as playbook for us to debug further?

Thanks,
Jennifer

Hey! I'm running into this as well. I've noticed that it's not host creation but rather when adding initiators to a host. I've tried adding the initiator in the same block that I'm creating the host and also tried adding the initiator after the host has been created. The host creation is idempotent but the initiator adding isn't.

This is an example of the latter.

- name: Create host
  delegate_to: 127.0.0.1
  register: iscsi_host
  dellemc.powerstore.host:
    array_ip: "{{powerstore_ip}}"
    validate_certs: false
    user: "{{powerstore_username}}"
    password: "{{powerstore_password}}"
    host_name: "{{inventory_hostname}}"
    os_type: "Windows"
    state: "present"

- name: Attach iSCSI initiator to host
  delegate_to: 127.0.0.1
  dellemc.powerstore.host:
    array_ip: "{{powerstore_ip}}"
    validate_certs: false
    user: "{{powerstore_username}}"
    password: "{{powerstore_password}}"
    host_name: "{{inventory_hostname}}"
    os_type: "Windows"
    initiators:
      - "iqn.1991-05.com.microsoft:{{inventory_hostname}}"
    initiator_state: "present-in-host"
    state: "present"

I get the following error message

"msg": "Adding initiators ['iqn.1991-05.com.microsoft:colo-HOST2-compile-executor-0'] to host colo-HOST2-compile-executor-0 failed with error HTTP code: 400, Bad Request [{'messages': [{'code': '0xE0A01001002D', 'severity': 'Error', 'message_l10n': 'One of the provided port names is already registered with another host. Please use port names unique to all hosts.'}]}]", "status_code": "400".

I'm confirmed that the initiator I'm attempting to add is the same initiator that's already added to the host. In fact, the ansible output from the create host shows that the initiator is the same.
