I’ve installed my first HBA (LSI 9300-8i 12Gbps SAS P16) pre-flashed in IT mode from ebay (the art of the server). I’ve connected two drives via CBL-TT028-01 cable.
I have several mirrored datasets consisting in two disks. For example, dataset X is consisting of 2 (mirrored) disks: One of which is connected to the motherboard’s SATA port, and the other one connected to the HBA itself.
Question is: How do I verify that the HBA is indeed working in IT mode and passing through these disks directly to TrueNAS?
All I did was to insert the HBA to the PCIE slot and connect the disks. This is the first time I’m doing this and I just want to check that everything is working as expected.

I’ve removed some of the address/serial numbers as I don’t think that data is necessary.
@SmallBarky yep, TrueNAS is installed directly on hardware. “Passthrough” I was refering to passing through the disks to TrueNAS itself (ie the HBA is not working as a RAID controller).
