7.3.5.1 How to Run VTDPY
Only one VTDPY session can be run on each controller at one time. Prior to
running VTDPY, be sure the terminal is set in NOWRAP mode. Otherwise, the
top line of the display scrolls off of the screen.
To initiate VTDPY from the maintenance terminal at the CLI> prompt, enter the
following command:
CLI> RUN VTDPY
To initiate VTDPY from a virtual terminal, refer to Section 8.3.1.
