Serial Port Snoop Setup Menu - IBM RS/6000 44P 270 Service Manual

Serial Port Snoop Setup Menu

This menu can be used to setup serial port snooping, in which the user can configure
serial port 1 as a "catch-all" reset device.
From the main service processor menu, select option 1, Service Processor Setup, then
select option 8 (Serial Port Snoop Setup Menu).
1. System reset string:
2. Snoop Serial Port:
98. Return to Previous 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 unit is
booted to AIX, whenever the reset string is typed on the main console, the system unit
uses the service processor reboot policy to restart. This action causes an EPOW (Early
Power Off Warning) 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.
