ConnectX®-4 onwards Adapter Cards Family

Upon first time device burning, the GUIDs, MACs and VPD of the device are required to be set on the flash.

The sections below demonstrate two methods of burning a new ConnectX®-4 onwards device in order to set these initial settings. Subsequent firmware updates will not change these settings.

For information regarding GUIDs, MACs and VPD, please refer to Accessing Remote InfiniBand Device by Direct Route MADs.

Method 1: Generating Firmware with Specific GUIDs and MACs and Burning it on the Device

In order to burn a new device, follow the steps below:

1. Disable the Write protection.

   # flint -d /dev/mst/mt521_pciconf0 -i ./ fw-ConnectX4- MCX454_Ax.bin -ocr -ignore_dev_data - allow_psid_change -nofs --yes burn
           

3. Set Write protection
