Error Analyzing - IBM p5 590 System Handbook

One significant improvement on the IBM Sserver p5 system HMC is to replace
the serial attachment method used on predecessor consoles, with a LAN
interface allowing high bandwidth connections to servers.
With the exception of the p5-590 and p5-595, administrators can choose to
establish a private service network, connecting all of their POWER5
processor-based servers and management consoles. Or they can include their
service connections in their standard operations network. The Ethernet LAN
interface also allows the HMC to be placed physically farther away from
managed servers, though for service purposes it is still desirable to install the
HMC in close proximity to the systems (within 8 meters or 25 feet is
recommended).
The HMC comes with an install wizard to assist with installation and configuration
of the HMC itself. This wizard helps to reduce user errors by guiding
administrators through the configuration steps required to successfully install the
HMC operating environment.
The Hardware Management Console provides a number of RAS features to the
servers it manages.
Automated Install/Maintenance/Upgrade
The HMC provides a variety of automated maintenance procedures to assist
in problem determination and repair. The Hardware Management Console
extends this innovative technology, providing automated install and
automated upgrade assistance. These procedures are expected to reduce or
eliminate service representative induced failures during the install or upgrade
processes.
Concurrent Maintenance and Upgrade
All IBM POWER5 processor-based servers provide at least the same level of
concurrent maintenance capability as was available in their predecessor
pSeries (POWER4) servers. Components such as power supplies, fans,
blowers, disks, HMCs, PCI adapters and devices can be repaired
concurrently (hot-service and replace).

6.6.3 Error analyzing

Since the service processor monitors the hardware environmental and FFDC
(FIR bits) activities, it is the primary collector of platform hardware errors and is
used to begin analysis and processing of these events. The service processor
will identify and sort errors by type and criticality. In effect, the service processor
initiates a preliminary error analysis to categorize events into specific categories:
