Trying to downgrade A620 controller

I want to downgrade the image in partition 0 of an A620 controller from 6.1.1 to 5.0.4 - the controller is booting from partition 1 (AOS 6.1.2).  The downgrade of partition 0 fails with an error stating that there is "Not enough free space (need 55 MB)".   I am not sure how to delete the image in partition 0.

 

What I am ultimately trying to do is upgrade some RAP5s from 3.1 to 5.0, so that I can connect them to my production controller, which is running 6.1.3.  I was hoping to downgrade this spare controller, connect the RAP5s to it, so that I could upgrade them, and then connect them to my production controller.

Re: Trying to downgrade A620 controller

On the CLI use "show storage command" and verify that you have  least 75 MB of /flash available.
If not, you must delete files from the file system before attempting a local
file upgrade. Run the dir command to list all files (or use WebUI > Maintenance > Files). Delete all unnecessary
files including crash files and logs.tar file. To ensure that all temporary (crash) files are removed, perform a tar
crash and then remove the crash.tar file from the controller. You can copy these files on your local computer for future purposes.

Make sure you clear your browser cache after the downgrade (and upgrade).

Re: Trying to downgrade A620 controller

Thank you, Sathya.  I can see from the output below that I only have 54MB of storage available in the /flash directory (file system /dev/mtdbblock1).  I assume from your response that this is where the uploaded image gets placed during the upgrade process.  I am not sure how to change to or list what is in the /flash directory, so that I know what I can know what to delete from here.

 

Filesystem                                     Size      Used      Available Use% Mounted on

/dev/mtdblock11                         156.0M    102.0M     54.0M  65% /flash

none                                           300.0M     41.7M    258.3M  14% /tmp

/dev/mtdblock9                            50.0M     24.3M     25.7M  49% /mnt/img0

/dev/mtdblock10                          50.0M     24.3M     25.7M  49% /mnt/img1

 

I also assume that the /mnt/img0 and img1 directories are partition 0 and partition 1?
