I installed the NAM3 and upgraded to 5.1 (2). I tried to apply the patches available for the image but it said its not a valid image for this platform.

Any ideas why this would say its not a valid image for the platform if Im on the 5.1-2 already ?

Answer 1

You're using the upgrade command, but in this instance its a patch so you need to use the patch command to load the specific patch
1. Download the patch onto a ftp server. Use the binary mode to download, not
ASCII. Verify that your local file MD5 checksum matches the one listed on CCO.
No modifications to the file are necessary after downloading. The file does not
require unzipping.
2. Login to the NAM CLI as the user root.
3. Run the patch command and specify the correct patch file URL. Use the
command "patch help" for the syntax of this command.
   Note 1: If you see an error message such as "Verification Failed, the patch
   you are trying to apply is not valid or not compatible with the release" it
   might be caused by an incorrect system-time setting on the NAM and/or
   Supervisor.  Adjust the system-time on the Supervisor or configure the NAM
   to use NTP and try the patch command again.
   Note 2: Sometimes during the "Stopping services" part of applying the
   patch, a status of "FAILED" may appear instead of "OK". For example, "FAILED"
   might appear when stopping the config_monitor process.  This message is not a
   problem as long as the message "Patch applied successfully" message
   eventually appears.  Reboot the NAM if this occurs.
4. The NAM will reboot and come up to a login prompt.
5. To see whether the patch is installed correctly, type the command
"show patches" in the NAM CLI.
