query on ansible

[mahesh g o]

I have below playbook:

i have put a loop, there are 8 aggr and 4 protocols: this playbook output is like after every 4 loop, it increments aggr and protocols. 

output of the playbook is:

svm1,svm2,svm3,svm4---aggr1 and nfs

svm5,svm6,svm7,svm8---aggr2 and iscsi

svm9,svm10,svm11,svm12---aggr3 and cifs

svm13,svm14,svm15,svm16---aggr4 and fcp

currently the ansible is failing because after 16th loop it is not finding any protocols.

but after 16th loop i want protcols to repeat :

expecting ouput:

svm17,svm18,svm19,svm20---aggr5 and nfs

svm21,svm22,svm23,svm24---aggr6 and iscsi

svm25,svm26,svm27,svm28---aggr7 and cifs

svm29,svm30,svm31,svm32---aggr8 and fcp

- hosts: localhost

  gather_facts: false

  vars_files:

    - /etc/ansible/group_vars/host_vars

  vars:

    aggr:

      - aggr_1

      - aggr_2

      - aggr_3

      - aggr_4

      - aggr_5

      - aggr_6

      - aggr_7

      - aggr_8

    protocols:

      - nfs

      - iscsi

      - cifs

      - fcp

  tasks:

    - name: Create SVM

      na_ontap_svm:

        state: present

        name: "svm{{ item }}"

        root_volume: "svm{{ item }}_root_vol"

        root_volume_aggregate: "{{ aggr[((item|int-1)//4)] }}"

        allowed_protocols: "{{ protocols[(((item)|int-1)//4)] }}"

        root_volume_security_style: mixed

        hostname: "{{ aiqumip }}"

        username: "{{ aiqumusername }}"

        password: "{{ aiqumpassword }}"

        https: false

      with_sequence: start=1 end=32

There is better way to handle all permutations. Replace with_sequence:

loop: "{{ aggr | product(protocols) | list }}"
loop_control:
index_var: "loop_index"

Then adjust your module parameters:

name: "svm{{ loop_index + 1 }}"
root_volume: "svm{{ loop_index + 1 }}_root_vol"
root_volume_aggregate: "{{ item[0] }}"
allowed_protocols: "{{ item[1] }}"

That should do the trick.

Thank u very much ...it worked.

I need one more help....the aggr is coming from the playbook1. every time i run that playbook1 individually and i enter the aggr array in  playbook2.

 so how do i get the output of the  playbook1 in the form of array so that i dont have to enter the aggr array in the  playbook2.

playbook2: is the one i shared earlier.

playbook1:

 tasks:

    - name: Create Aggregates and wait 5 minutes until aggregate is online

      na_ontap_aggregate:

        state: absent

        service_state: online

        name: "aggr_{{item }}"

        disk_count: 5

        wait_for_online: True

        nodes: "{{ node[((item|int-1)//2)] }}"

        time_out: 300

        hostname: "{{ aiqumip }}"

        username: "{{ aiqumusername }}"

        password: "{{ aiqumpassword }}"

        validate_certs: false

        with_sequence: start=1 end=8

First question would be why do you have two separate playbooks?

I am newbie to ansible....i have to create many objects like this(aggr,svm,volumes,luns,policies,network interfaces) so i have created playbook for each objects and thought of stitching it together.

Yes it is good idea to split up tasks logically, but not a good idea to use separate playbooks:

You can group them in task files,.e.g.

tasks:
- import_tasks: aggr.yml
- import_tasks: svm.yml

[mahesh g o]

okay, so if i use them as tasks, will svm.yml takes aggr array from aggr.yml??
