Repeated the following procedure for each “upgrade hop”.
The Switch OS software packages include the switch firmware and the CPU software for the specific switch board CPU (x86).
Installing the CPU software also automatically installs the embedded firmware. Similarly, once the OS is upgraded, the firmware is upgraded as well.
The switch’s OS image and its documentation collateral (release notes, user manual) can be found in MyMellanox.
Run the following commands in order to upgrade (in this example, upgrading to version 3.9.0606):
switch (config)#image delete XXX // --> delete old images one at a time, if exist
switch (config)#image fetch scp://root:password@server/path-to-image/image-X86_64-3.9.0606.img
switch (config)#image install image-X86_64-3.9.0606.img
switch (config)#image boot next
switch (config)#configuration write
switch (config)#reload
Wait a few minutes to allow the OS’s upgrade process to complete, and then reconnect to the system.
In order to verify that the installation was completed successfully, run:
# show version
