How to add or passing through a physical drive to VM in Proxmox

 I have a Open Media Vault file server hosted on Proxmox VM to share across the printer scan data and also to share files between all of my network attached windows pc's. 

I found this solution works fine:

First you need to find out your disk you wants to share or pass through: 

• In my Proxmox PVE > Disks > /dev/sdb

And you also need your Proxmox VM ID where you wants to add the disk:

• In my Proxmox VM ID - 115

Now we need to find out the disk SCSI ID (in my case it is not SCSI ID):

• Go to shell and enter below command
• ls -n /dev/disk/by-id/
• My disk ID - wwn-0x50014ee214065158

Now you need to pass through the disk as you got the SCSI ID and your VM ID:

• Here is the command (you need to modify) -/sbin/qm set [VM-ID] -virtio2 /dev/disk/by-id/[DISK-ID]
• /sbin/qm set 115 -virtio2 /dev/disk/by-id/wwn-0x50014ee214065158

But before entering the command let's see if we have any attached alternative disk with our VM:

Nothing is there, now let's start adding the disk by putting the command:

/sbin/qm set 115 -virtio2 /dev/disk/by-id/wwn-0x50014ee214065158

Boom - It's added - see the image

Hope this will help me again and also people who need help in the similar will be found as helpful.
