This guy managed to cross-flash and now is selling it on ebay. https://www.ebay.com/itm/LSI-9400-8i-Lenovo-530-8i-12Gbps-Tri-Mode-SAS-SATA-NVMe-HBA-P9-IT-mode-ZFS/163533879633 "They have been cross-flashed to Avago / LSI 9400-8i Tri-Mode IT (Initiator Target) firmware version P9 (specifically 09.00.03.00)." but yeah looking at the 9400-8i page I don't see anything mentioning IT mode, or that specific version. I'm guessing they removed that firmware since its probably out of date, but now wondering if the firmware up there supports IT mode.
