How can I find missing value of lun_id ? | NetApp | Page 1

Apologies beforehand as this is more of an ansible issue than NetApp Ontap, but I cannot figure out how to calculate a certain value.

let's imagine this scenario, I will have a list of LUN mapping ID:

If I deleted the LUN with LUN mapping ID = 11, my playbook gives me 14 as the next lun_id value. What I want is for the playbook to have this list

10
12
13
and check if a number is missing, in this case is 11 so the next lun_id would be 11 and not 14 . Same thing if I deleted 11 and 12 the list would be :
10
13
so the next lun_id would 11 and the next run would be 12

There is also the condition that the lun_id should always be > 10.

Here is my current code :

name: Build LUN Mapping list
when: lun_map_output.msg.num_records | int > 0
block:
- name: Make LUN Mapping list
  ansible.builtin.set_fact:
  lun_map_list: "{{ lun_map_list | default({}) | combine({ index_lun_map.path: index_lun_map.lun_id }) }}"
  loop: "{{ lun_map_output['msg']['records'] }}"
  loop_control:
  loop_var: index_lun_map
- name: Get Latest LUN Mapping ID
  ansible.builtin.set_fact:
  lun_map_last_id: "{{ item.value | int }}"
  with_items: "{{ lun_map_list | dict2items | sort(attribute='value') }}"
name: Define LUN Mapping list when none exist
when: lun_map_output.msg.num_records | int == 0
ansible.builtin.set_fact:
lun_map_last_id: 0
name: Set calculated LUN ID
ansible.builtin.set_fact:
lun_map_chosen_id: "{{ ( lun_map_last_id | int + 1 ) if ( lun_map_last_id | int != 0 ) else 10 }}"
`

Could you guys let me know how can I achieve this ? Thanks a lot.
