I’m running this way on one of my servers. It’s fine if you pass the entire HBA over (make sure it’s in IT mode for Proxmox).

Alternatively you can map each drive over by disk-by-id mappings as I’m doing on this one. I haven’t dealt with a drive failure yet, but from what I read it’s just a little bit of a headache to re-add the drives later. “Not recommended”, but ok if you know what you’re doing.
