Hard Drives issue on FreeBSD 12.2

[michaels2408]

Good morning,
I am new to FreeBSD and need some guidance. I have a system where FreeBSD is virtualized on a proxmox server. My SAS backplane exposes all 10 sas drives to both of my sas controllers, so when I pass one of the controllers to FreeBSD it sees all of the drives. Problem is that 3 of the 10 drives are used for a proxmox ZFS pool, which the FreeBSD vm drive lives on. When FreeBSD boots and probes these three drives it causes read/write errors that force the pool offline. So, question is, how do force FreeBSD to probe only the 7 drives used for my FreeBSD ZFS pool and leave the other three drives alone?

Any help or guidance would be greatly appreciated.

Thanks,
Mike

Ok. So I installed FreeBSD in the exact same scenario as mentioned previously and reworded my question to fit the forum guidelines.

Mutipath setup?

This breaks your multipath setup.

You don't. Your setup is wrong to begin with.
