Hi Nivas,
VM will be hosted on the datastore and datastore in return will have an naa id.
Click on the datastore tab and select the datastore -->VMs to see what are all the VMs hosted on that datastore.
Also from datastore navigate to configure-->device backing to find the naa id of the datastore.
Kindly use the below command
Ex: lun show -serial-hex 383046786bxxxd7250747xx1.
Kindly note 600a0980 refers to the NetApp vendor.
