Cisco DNA Center Upgrades pain

[Des-cassidy]

use winSCP sftp protocol to transfer files to Catalyst centre "root" directory.

When I ssh onto the appliance I am unable to access the root directory and therefore unable to locate files.

Raised a TAC case to walk me through Catalyst filesystem....

Unless this is an airgap deployment, you don't need to transfer any files to the Catalyst Center to upgrade. If you are transferring files to upgrade via airgap, then you should already have a TAC case open as they will need to provide the files to begin with.

So why are we attempting to access the file system?

You are quite correct I am running an air gapped system. I am in touch with Cisco TAC and I have a Cisco CCIE on site to carry out these upgrades. Will the help of Cisco I managed to uncover .magshell this is the missing link I was looking for.

If you want to use the cd command you must be in restricted shell

To access the magshell, you can use the following command: cd /home/maglev/.magshell/artifacts

please save all files in the artifacts directory as this directory has the most space and will not cause service disruption of the partition gets full.
