Hot swap physical Proxmox disk to VM

Okay, so I'm trying to run a FreeBSD VM on a bench testing Proxmox server. I have an disk array attached via LSI HBA with 24 disks. I'm passing the physical disks to the VM via the VM.conf file using scsi8: /dev/disk/by-id/ata-ST1000LM035-1RK172_ZDE82Y5F. Everything runs just fine. The VM starts up and i can see the physical disk has been passed through.

Now I want to hot swap the drive in case of a failure. I've pulled the old hard drive out of the enclosure and put the new one in. Proxmox see the new drive just fine. I've changed the VM.conf file to include the id of the new drive (scsi8: /dev/disk/by-id/ata-WDC_WD10JPVX-22JC3T0_WD-WX81A6415JVC).

Now, the VM (FreeBSD) doesn't see the new drive? I have the hotplug option for disks, network and usb check in the Proxmox VM Options.

The goal here is to pass the replacement drive to the VM without rebooting...hence hotplug

I thought there might be a "qm" command to trigger the hotswap but I'm not sure.

Any help would be appreciated!

Hotplug does not work passthrough disks.
You could add the disk manually with the KVM monitor

qm monitor <VMID>
