VM halted after the passthrough disk is disconnected

[lionux]

Dear All;

I have a VM that I used as a NAS and it works like a charm except that when I remove the disk (in passthrough mode), Proxmox halt the VM.
I understand the logic, but in my case, the VM should not be stopped but should continue to run since the harddisks are setup in RAID2 mode.

How can I set proxmox for this VM to not halt the VM in case of harddisk passthrough failure?

Thanks.
