Hi Doug O'Leary,
I came up with this -
tasks:
- name: Get all disks in all controllers
vmware_guest_disk_info:
validate_certs: False
hostname: '{{ vcenter_hostname }}'
username: '{{ vcenter_username }}'
password: '{{ vcenter_password }}'
datacenter: Asia-Datacenter1
name: VM_8046
register: existing_disk
- name: Create a dict with controller and the total number of disks
set_fact:
disk_info: "{{ disk_info | default({}) | combine({
item.value.controller_bus_number : item.value.unit_number} )}}"
with_dict: "{{ existing_disk.guest_disk_info }}"
- debug:
msg: "{{ disk_info }}"
Here, I am iterating over all disks and controllers in the given VM. I get
a final count of all disks available on each controller in disk_info
dictionary. Once I have that information I can figure out what is next disk
in the given controller.
Also, you can take a look at this example to add more disk using
vmware_guest_disk -
https://github.com/Akasurde/ansible-reproducers/blob/master/55999/i55999.yml
Let me know if you need any help on this.
Thanks,
Abhijeet Kasurde
