After

you

have

set

up

your

system,

we encourage

you

to

visit

the

Compu

Web site. Good ergonomic practice is important to get the most from your

 

workstation and to avoid discomfort. This means that the equipment and

the

 

workplace should

be

arranged to suit

your individual

needs

and

the

kind of

work

do.

Using the Service Processor and Service Director Features

The Service Processor and Service Director features protect users against unnecessary system downtime by keeping support personnel (both internal and external) aware of any unexpected changes in the system environment. In combination, the two features provide a flexible solution to automated system maintenance.

Service Processor

The Service Processor runs on its own power boundary

and

continually monitors

 

 

hardware attributes, the AIX operating system, and

the

environmental

conditions

 

within the

system. Any

system failure which prevents

the

system

from

returning

to

an operational state (a fully

functional AIX operating system) is

reported

by

th

Service Processor. The Service Processor is controlled

by

firmware

and

does

not

 

require the AIX operating system to be operational

to perform its tasks. If an

system failures are detected, the Service Processor can take predetermined

 

corrective

actions. The

methods

of corrective actions

are:

 

 

 

 

ŸSurveillance

ŸCall Home

ŸAIX Operating System Monitoring

Surveillance is a function in which the Service Processor monitors the system through heartbeat communication with the systemheartbeatfirmwareis. Thea

periodic signal that the firmware can monitor. During system startup, the firmware surveillance monitor is automatically enabled to check for heartbeats from the firmware. If a heartbeat is not detected within a default period, the Service Processor attempts to reboot the system until the system either restarts success
