To upgrade MLNX-GW, perform the following steps.
Enter Config mode.
Display the currently available image (.img file).
Delete the image listed under “Images available to be installed” prior to fetching the new image. Use the command “image delete” for this purpose.
When deleting an image, it is recommended to delete the file, but not the partition, so as to not overload system resources.
Fetch the new software image.
Display the available images again and verify that the new image now appears under “Images available to be installed”.
Install the new image.
CPU utilization may go up to 100% during image upgrade.
Have the new image activate during the next boot.
Run “show images” to review your images.
Save current configuration.
Reboot to run the new image.
After software reboot, the software upgrade will also automatically upgrade the firmware version.
