This menu can be used to setup serial port snooping, in which the user can configure
serial port 1 as a

reset device.
From the main service processor menu, select option 1, Service Processor Setup
Menu, then select option 8 (Serial Port Snoop Setup Menu).

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 is booted
to AIX, whenever the reset string is typed on the main console, the system uses the
service processor reboot policy to restart. This action causes an early power off warning
(EPOW) to be logged, and also an AIX dump to be created if the machine is at an AIX
prompt, with AIX in such a state that it can respond. If AIX cannot respond, the EPOW
record is created, rather than the AIX dump.
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.
