I want to add a FC LUN to vm and share the same FC LUN to other vm's under the same ESX host. How to achieve this through perl SDK

There are 4 vms under the same ESXi (vm1, vm2, vm3 and vm4). All 4 vm's are created with one "SCSI Controller 0" by default with LsiLogicController Parallel.

I want to add a FC(Fiber Channel) LUN to vm1 and share the same FC LUN to other vm's(share with vm2, vm3 and vm4) under the same ESX host. I need to do this for around 800 ESX hosts which has 4 vm's as explained.

Steps:

1. Add FC LUN to vm1.

2. Share the same FC LUN to vm2, vm3 and vm4

3. Repeat 1 and 2 for around 800 ESXi hosts.

Can you please share  the approach using vsphere Perl SDK. I am stuck as many forums give different approaches with different errors explained(I am confused and did not understand the approach)
