6.6.4 Service processors

The service processor provides for excellent RAS service features such as First
Failure Data Capture analysis explained in the prior availability section and
surveillance monitoring described previously. It also provides functions such as;
power-on and off of the system, reading the service processor and POST error
logs, reading vital product data, changing the bootlist, viewing boot sequence
history, and changing service processor configuration parameters, all of which
can be performed remotely. clients can enable console mirroring on the system
console so they can monitor all remote console activity. For this option to work, a
modem must be attached to one of the serial ports and configured appropriately.
The service processor in the p5-590 and p5-595 product is an improved design
when compared to the service processor that was available in the IBM POWER4
processor-based systems. The main service processor function in p5-590 and
p5-595 is located in the CEC and is based on the new hardware. The CEC
contains two service processor cards. The new service processor subsystem is
