5th Generation (Group II) Devices
On 5th Generation (Group II) devices, the “sg” command can operate on both the image file and the
image on the flash. When running the “sg” command on an image on the flash, -uid flag must be
specified. For ConnectX-4, -guid/-mac flags can be specified. By default, 8 GUIDs will be assigned
for each port starting from base, base+1 up until base+7 for port 1 and base+8 up until base+15 for
port 2.
To change the step size and the number of GUIDs per port, specify
guids_num=<num> step_size=<size> to the sg command.
