I’ve download the firmware from your FTP site for infiniband on X8DTT-HIBQF+ :
https://www.supermicro.com/wdl/Firmware/InfiniBand/X8DTT-(H)IBQ(F)/X8DTT-IBQ_20110622_ConnectX-2_291.bin
On the flash mode I get an error:
PSID mismatch. The PSID on flash (SM_2122000001000) different from the PSID in the given image (SM_2092000001000)
You can add “-allow_psid_change” to the command to flash the IB.
