Use the efa deploy nographics command.
The efa deploy nographics command does not display any graphics progress bar. The SLX will only display text about what is getting installed. When you use the "nographics" option, the system prompts you for all the required inputs.
You can also continue using the existing efa deploy -–graphics no command.
NoteYou cannot use the efa deploy nographics and efa deploy -–graphics no commands together.
