Rev 1.6.9 In case you are downloading to an older software version which has never been run yet on the switch, use the following command sequence as well: switch (config) # no boot next fallback-reboot enable switch (config) # configuration write Step 7. Reload the switch. Run: switch (config) # reload 4.2.3.3 Switching to Partition with Older Software Version The system saves a backup configuration file when upgrading from an older software version to a newer one. If the system returns to the older software partition, it uses this backup configuration file. Note that all configuration changes done with the new software are lost when returning to the older software version. There are 2 instances where the backup configuration file does not exist: • The user has run "reset factory" command, which clears all configuration files in the system • The user has run "configuration switch-to" to a configuration file with different name then the backup file Also note that the configuration file becomes empty if the switch is downgraded to a software version which has never been installed yet. To allow switching partition to the older software version, in these cases above, follow the steps below: Step 1. Run the command: switch (config)# no boot next fallback-reboot enable Step 2. Set the boot partition. Run: switch (config)# image boot next Step 3. Save the configuration. Run: switch (config)# configuration write Step 4. Reload the system. Run: switch (config)# reload 4.2.4 Upgrading System Firmware Each MLNX-OS software package version has a default switch firmware version. When you update the MLNX-OS software to a new version, an automatic firmware update process will be attempted by MLNX-OS. This process is described below. 4.2.4.1 After Updating MLNX-OS Software Upon rebooting your switch system after updating the MLNX-OS software, MLNX-OS software will first compare its default firmware version with the currently programmed firmware versions on all the switch modules (leafs and spines on director-class switches, or simply the switch card on edge switch systems).

Step 7.

Reload the switch. Run:

4.2.3.3

Switching to Partition with Older Software Version

The system saves a backup configuration file when upgrading from an older software version to a

newer one. If the system returns to the older software partition, it uses this backup configuration

file. Note that all configuration changes done with the new software are lost when returning to

the older software version.

There are 2 instances where the backup configuration file does not exist:

•

The user has run “reset factory” command, which clears all configuration files in the

system

•

The user has run “configuration switch-to” to a configuration file with different name

then the backup file

Also note that the configuration file becomes empty if the switch is downgraded to a software

version which has never been installed yet.

To allow switching partition to the older software version, in these cases above, follow the steps

below:

Step 1.

Run the command:

Step 2.

Set the boot partition. Run:

Step 3.

Save the configuration. Run:

Step 4.

Reload the system. Run:

4.2.4

Upgrading System Firmware

Each MLNX-OS software package version has a default switch firmware version. When you

update the MLNX-OS software to a new version, an automatic firmware update process will be

attempted by MLNX-OS. This process is described below.

4.2.4.1

After Updating MLNX-OS Software

Upon rebooting your switch system after updating the MLNX-OS software, MLNX-OS software

will first compare its default firmware version with the currently programmed firmware versions

on all the switch modules (leafs and spines on director-class switches, or simply the switch card

on edge switch systems).

In case you are downloading to an older software version which has never been run yet

on the switch, use the following command sequence as well:

switch (config) # no boot next fallback-reboot enable

switch (config) # configuration write

switch (config) # reload

switch (config)# no boot next fallback-reboot enable

switch (config)# image boot next

switch (config)# configuration write

switch (config)# reload
