Upgrading VDX over SCP

Upgrading VDX over SCP

I'm having trouble figuring out how to upgrade my VDX 6940-36Q switch with Network OS 6.0.0 to version 7.0.2 over SCP. I am currently connected to the switch by serial, management port & an in-band connection. I have been unable to launch the firmware upgrade tool to select the package for install. I have found resources relating to doing such an upgrade with NOS 7.0, but not with 6.0. I was wondering if this is even possible, and if it is--how should I go about doing it.

Furthermore, I was wondering which SWBD I should select for my switch.

Thanks!!

The issue looks to be a directory structure or user login issue.

From the switch, can you try to ssh directly to the SCP server to confirm reachability? For example:

code:
sw0# ssh 10.229.48.1 -l ian vrf mgmt-vrf



Once you connected to your SCP server, run the following and paste it back here:

code:
$ ls -R /home/ian/nos7.0.2 | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/  /' -e 's/-/|/' | head -20



So, I can see your directory structure. Depending on how you decompress the files, it may tier the folders multiple times which could cause this error as the script is not able to find the firmware files.

For example, you may need to run:

code:
firmware download scp host 10.229.48.1 user *** directory /home/ian/nos7.0.2/nos7.0.2 password *********** coldboot



Lastly, the latest target path release for 7.x is 7.0.2b which has a good number of fixes and considered stable. I would recommend upgrading to 7.0.2b if you are planning to run it long term.

Hello,

The upgrade process for 6.0 and 7.0 is the same. In general, the upgrade process is the same for all NOS versions.

Please see the firmware upgrade guide at the below link:

https://documentation.extremenetworks.com/networkos/SW/70x/nos-702b-upgrade-guide.pdf

See page 23. You can upgrade using SCP with the 'firmware download interactive' command.

You don't need to select the SWBD directory. All you need to do is specify the firmware directory location on the SCP server in the 'firmware download interactive' command. Then, the command will know which SWBD directory to use and which files to download for the upgrade process for your switch model.

When upgrading from 6.0.0 -> 7.0.2b, you will need to use the 'coldboot' option to have the switch reboot as a part of the firmware upgrade process.

By default, the switch uses the management port for the firmware download.

Thanks,
