# scli --start_upgrade

This command should only be used when intending to upgrade the entire system to a new product version. Press 'y' and then Enter to confirm.y

Error: MDM failed command.  Status: Invalid session. Please login and try again.

Also,  commands like:

# scli --query_user --username admin

Error: MDM failed command.  Status: Invalid session. Please login and try again.

# scli --query_all

Error: MDM failed command.  Status: Invalid session. Please login and try again.

fails also.

Any ideas ?
