Aborting a firmware upgrade during the copy phase?

Any possible way to abort the firmware upgrade?

 

I made the mistake of using TFTP and it is taking over 1 hour to copy the firmware over and I cannot SSH into the controller at this time.

 

Is there any way to abort this process?

Please contact TAC so you are guided through this properly.  Typically if you disconnect the connection, it will not finish.  If you cannot SSH into it, that is a problem.  Please contact support.

A simple ctrl-C won't work in this case?

 

The controller is in a remote location unfortunately and no console access.

 

I guess TAC is the best solution?

I would say you should be able to.  If you cannot get into the CLI again, something must have occurred.  Please contact TAC to get this sorted.

ctrl-c didn't work.

 

I do have remote PDU access to the controller. I could possibly reboot it.

The firmware hasn't finished copying over therefore I should be able to reboot it safely. I think anyway...

In my experience you can not ssh into the controller while it is TFTPing.  I think this is normal behavior.  Once it is done you should be able to log back in.  An hour or more is common when TFTPing the images.

Probably the biggest issue is that TFTP really should not take that long, and some TFTP servers cannot transfer files over 50meg and hang as a result.  It is much faster to use FTP in any situation that you can.  With that being said, some sites are on slow WAN links and it is much better to copy the file to a local host and then TFTP or FTP it from there.

I've seen this once or twice.  My solution was to stop the TFTP service/application on the system hosting the image; it should cause the controller to abort the connection.
