I have my code written like below .
But i am not able to get proper List of dictionary.

I have 2 list

my_hard_disk_converted_to_GB:
  - device_id: 2
    size: 32212254725
    size_gb: 30
  - device_id: 3
    size: 32212254724
    size_gb: 30


san_mount_list_converted_to_GB:
  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 29.85
    size: 32212254723
    mount_point: H

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.75
    size: 10475277144
    mount_point: F

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.78
    size: 10475277145
    mount_point: H

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.74
    size: 10475277143
    mount_point: G

I want to create a final_list
which will add device_id on san_mount_list_converted_to_GB and doesn’t cross size_gb of my_hard_disk_converted_to_GB.

san_mount_list_converted_to_GB:
  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 29.85
    size: 32212254723
    mount_point: H
    device_id: 2

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.75
    size: 10475277144
    mount_point: F
    device_id: 3

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.78
    size: 10475277145
    mount_point: H
    device_id: 3

  - no_of_vols: 1
    cap_unit: 'BYTES'
    size_gb: 9.74
    size: 10475277143
    mount_point: G
    device_id: 3

What is the relationship between items in the two lists? Put another way, how are you supposed to know what device_id each item in san_mount_list_converted_to_GB gets?

my_hard_disk_converted_to_GB:
- device_id: 2
size: 32212254725
size_gb: 50
- device_id: 3
size: 32212254724
size_gb: 50
- device_id: 4
size: 32212254723
size_gb: 50

san_mount_list_converted_to_GB:
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 49.84
size: 50475274245
mount_point: G
device_id: 12
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 9.84
size: 10475274245
mount_point: G
device_id: 13
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 39.85
size: 404752742465
mount_point: F
device_id: 13
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 9.87
size: 10475274240
mount_point: F
device_id: 14
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 19.89
size: 11932554240
mount_point: H
device_id: 14
- no_of_vols: 1
cap_unit: ‘BYTES’
size_gb: 19.92
size: 11932554240
mount_point: I
device_id: 14

This is new 2 list I have now … It is having only size sum match … where device_id is different.
So 2 supposed to be replaced 12
So 3 supposed to be replaced 13
So 4 supposed to be replaced 14

4

Im afraid I still dont understand the relationship between the two lists. I dont see any matching sizes or size_gbs in the two lists

So 2 supposed to be replaced 12
So 3 supposed to be replaced 13
So 4 supposed to be replaced 14

I dont understand this either. Are you saying device_id 2 should be replaced with device_id: 12? Or the second item in the first list should be replaced by the 12th item in the second list?

server 'A" was having 3 LUN DIsk [with ID 12 and 13 and 14] and was having drives created over there. [List : san_mount_list_converted_to_GB].

I got server ‘B’ which is having same count of disk [with ID 2 and 3 and 4]
I want to create same drive over server ‘B’. [List :my_hard_disk_converted_to_GB].

Since Server ‘B’ don’t have 12,13,14 I want them to be replaced by 2,3,4 respectively.

Hope this helps. If you wanted to specify your own device ID mapping, the playbook could be simpler
