Managing RAS Features and System
Firmware

This chapter describes how to manage reliability, availability, and serviceability
(RAS) features and system firmware, including ALOM CMT on the system
controller, and automatic system recovery (ASR). In addition, this chapter describes
how to unconfigure and reconfigure a device manually, and introduces multipathing
software.

This chapter contains the following sections:

■

“ALOM CMT and The System Controller” on page 27

■

“OpenBoot Emergency Procedures” on page 33

■

“Automatic System Recovery” on page 35

■

“Unconfiguring and Reconfiguring Devices” on page 40

■

“Displaying System Fault Information” on page 41

■

“Multipathing Software” on page 42

■

“Storing FRU Information” on page 43

Note –

This chapter does not cover detailed troubleshooting and diagnostic

procedures. For information about fault isolation and diagnostic procedures, refer to
the service manual for your server.

ALOM CMT and The System Controller

The ALOM CMT system controller supports a total of nine concurrent sessions per
server, eight connections available through the network management port and one
connection through the serial management port.
