I want to create a final_list

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

device_id: 3

cap_unit: 'BYTES'

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:
san_mount_list_converted_to_GB:
This is new 2 list I have now … It is having only size sum match … where device_id is different.
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
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]
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

Could you enclose the YAML in three backticks to improve the formatting? See for example the GitHub guide .
