How to Flash an HBA Card to IT Mode (Step-by-Step Guide)
You've got your HBA card — great choice. But if it arrived running IR (Integrated RAID) firmware, it won't work the way you need it to with Unraid, TrueNAS, Proxmox, or any ZFS-based system. You need to flash it to IT (Initiator Target) mode, which turns the card into a pure passthrough device: drives talk directly to your OS, no RAID middleman in the way.
This is one of the most-asked questions from new HBA buyers, and it has a reputation for being confusing — partly because there are slightly different steps for different cards, different methods (DOS vs UEFI), and several old forum posts with missing files or broken links. This guide covers it all in one place for the cards we sell: the DELL H310, Fujitsu D2607, LSI 9207-8i, DELL H200, and the LSI 9211-8i.
