To upgrade MLNX-GW, perform the following steps.
Enter Config mode.
gateway > enable gateway # configure terminal gateway (config) #
Display the currently available image (.img file).
gateway (config) # show images Installed images: Partition 1: <old_image> Partition 2: <old_image> Last boot partition: 1 Next boot partition: 1 Images available to be installed: webimage.tbz <old_image> Serve image files via HTTP/HTTPS: no No image install currently in progress. Boot manager password is set. Image signing: trusted signature always required Admin require signed images: yes Settings for next boot only: Fallback reboot on configuration failure: yes (default)
Delete the image listed under “Images available to be installed” prior to fetching the new image. Use the command “image delete” for this purpose.
gateway (config) # image delete <old_image>
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.
gateway (config) # image fetch scp://<username>:<password>@<ip-address>/var/www/html/<new_image> Password (if required): ****** 100.0%[##################################################################]
Display the available images again and verify that the new image now appears under “Images available to be installed”.
To recover from image corruption (e.g., due to power interruption), there are two installed images on the system. See the commands “image boot next” and “image boot location” for more information.
gateway (config) # show images Installed images: Partition 1: <old_image> Partition 2: <old_image> Last boot partition: 1 Next boot partition: 1 Images available to be installed: webimage.tbz <new_image> Serve image files via HTTP/HTTPS: no No image install currently in progress. Boot manager password is set. Image signing: trusted signature always required Admin require signed images: yes Settings for next boot only: Fallback reboot on configuration failure: yes (default)
Install the new image.
gateway (config) # image install <new_image> Step 1 of 4: Verify Image 100.0% [#############################################################] Step 2 of 4: Uncompress Image 100.0% [#############################################################] Step 3 of 4: Create Filesystems 100.0% [#############################################################] Step 4 of 4: Extract Image 100.0% [#############################################################]
CPU utilization may go up to 100% during image upgrade.
Have the new image activate during the next boot.
gateway (config) # image boot next
Run “show images” to review your images.
gateway (config) # show images Installed images: Partition 1: <new_image> Partition 2: <old_image> Last boot partition: 1 Next boot partition: 1 Images available to be installed: webimage.tbz <new_image> Serve image files via HTTP/HTTPS: no No image install currently in progress. Boot manager password is set. Image signing: trusted signature always required Admin require signed images: yes Settings for next boot only: Fallback reboot on configuration failure: yes (default)
Save current configuration.
gateway (config) # configuration write
Reboot to run the new image.
gateway (config) # reload Configuration has been modified; save first? [yes] yes Configuration changes saved. Rebooting... gateway (config)#
After software reboot, the software upgrade will also automatically upgrade the firmware version.
