Chapter 3 55
Guardian Service Processor (GSP)
The Guardian Service Processor (GSP) is a new console subsystem on
N4000, all L-Class models, the new A-Class machines (the A400 and
A500), Superdome systems, and all new servers introduced starting with
the N-Class. The GSP console driver, the software component of the GSP,
provides the following features on HP-UX:
Local console port providessystemconsole while HP-UX
is running.
Remote session port establishes an HP-UX login session
on the remote console.
Local session port establishes an HP-UX login session
on the local console.
Internal console port supports firmware upgrade and
diagnostics on GSP.
UPS port establishes a communication channel
between the UPS daemon and UPS.
SAM provides configuration support (that is, modem and UPS
connections) over the GSP serial ports. The insf (1M) and mksf (1M)
commands create device files for the GSP serial ports.
The following commands have been changed to provide additional
support for the GSP console:
• ttytype can determine the ID of the terminal connected to the local
console port.
• stty supports status query and reset function of the GSP.
The GSP console driver is based on the existing built-in serial port driver
(asio0). Every serial port on the GSP adheres strictly to the termio
feature set; these features are described in the termio (7) and modem (7)
manpages.
GSP Logging Capabilities
The introduction of GSP to the above platforms dramatically changes the
way chassis operations and diagnostic evaluations are performed on a
running system.
