Service Processor (GSP or MP)
NOTE The service processor in HP servers is sometimes called the Management Processor (MP)
and sometimes the Guardian Service Processor (GSP).
Regardless of the name, the service processor in these servers provides approximately
the same features and performs essentially the same role.
Throughout this document the term “service processor” refers to both the MP and GSP
service processors.
The service processor is a service and console subsystem on the following servers:
• N4000
•all L-Class
• A-Class (the A400 and A500)
• Superdome systems
• rp2400, rp2450
• rp5400, rp5430, rp5450, rp5470
• rp7400, rp7410
• rp8400
• 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 provides system console 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 the 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.
