- MAC base address value. Each of the two ConnectX EN ports is assigned

a MAC address as follows:

MAC is assigned to Port 1

MAC+1 is assigned to Port 2

Affected commands: burn sg

-macs <MACs...>

- 2 MAC addresses must be specified here—one for each ConnectX EN

port. The first MAC address is assigned to Port 1 and the second MAC

address to Port 2.

Affected commands: burn sg

UIDs are derived from the given base UID as per Mellanox’s methodol

ogy.

Affected commands: burn, sg

Affected commands: burn, sg

-blank_guids - Burn the image with blank GUIDs and MACs (where applicable). These

values can be set later using the “sg” command (see details below).

NOTE: An image that is burnt with blank GUIDs/MACs will fail to boot

the machine as long as the GUIDs/MACs are not set.

Affected commands: burn

-clear_semaphore - Force the clearing of the Flash semaphore on the device. This flag should

come BEFORE the -d[evice] flag in the command line. No command is

allowed when this flag is used.

NOTE: Using this flag may result in an unstable behavior and flash image

corruption if the device or another flash application is currently using the

flash. Handle with care.

-byte_mode - Shift the address when accessing Flash internal registers. May be required

for burn/write commands when accessing certain Flash types on Infini

Host®IIIEx HCAs.

-no_flash_verify - Do not verify each write on the Flash device.

1. The -mac and -macs options are applicable only to Mellanox Technologies Ethenet adapter and switch devices.
