Hi Sadanand,

Can you try this, this will give you all extent of given VMFS volume and then you can extract diskName

- name: Get all Datastore facts  
vmware\_datastore\_info:  
validate\_certs: False  
hostname: ‘{{ vcenter\_hostname }}’  
username: ‘{{ vcenter\_username }}’  
password: ‘{{ vcenter\_password }}’  
datacenter: “Asia-Datacenter1”  
name: ds\_171\_1  
schema: vsphere  
register: all\_datastores

- debug:  
msg: “{{ item.info.vmfs.extent }}”  
with\_items: “{{ all\_datastores[‘datastores’] }}”
