Use the system reset string option to enter the system reset string, which resets the
machine when it is detected on the main console on serial port 1.
Use the snoop serial port option to select the serial port to snoop.
Note: Only serial port 1 is supported.
After serial port snooping is correctly configured, at any point after the system unit is
booted to AIX, whenever the reset string is typed on the main console, the system
unit reboots.
Pressing Enter after the reset string is not required, so make sure that the string is
not common or trivial. A mixed-case string is recommended.
