If you passthrough a device to an app, is it also available to another app?

Scenario: TN Scale virtualized in Proxmox. HBA with 16 drives attached passed through to TN Scale, but not all 16 drives are used by TN.
Question: Can Proxmox and other VMs running on Proxmox still use drives on that HBA that are NOT in use by TN?

Thanks in advance!

Not that I have ever tried - but no - the device (HBA) is run and controlled by TN

Thanks, NugentS. An answer of "NO" is what I assumed but I had to ask.

As I understand passthrough, it means "A passed through device is now attached only to the specified host/app". But, I've never tried using a passed through device with another "assigned device" either.

Bottom line: Buy more HBAs. EBay, here I come.

I'm trying to fast forward through a few months of trial and error in order to get my new "virtualized everything server" up and running with as few issues as possible. :smile:
