IBM RS/6000 7025 manual Service Processor System Monitoring Surveillance

Service Processor System Monitoring - Surveillance

Surveillance	is a	function	in which the Service Processor monitors the system, and
the system monitors the Service Processor. This monitoring is accomplished by
periodic	samplings	called	heartbeats.

Surveillance is available during two phases:

1.System firmware bringup (automatic) and

2.Operating system runtime (optional).

System Firmware	Surveillance:	Provides the Service Processor with a means
to detect	boot failures	while the system firmware is running.

System firmware surveillance is automatically enabled during system power-on. It cannot be disabled via a user selectable option.

If

the

Service

Processor detects no heartbeats during system IPL

(for

7

minute

cycles the system power to

attempt a reboot. The maximum

number

of

retries

is

from the Service Processor menus. If the fail condition repeats, the Service

Processor

leaves

the

machine

powered

on,

logs an

error

and

offers

menus

to

the

user. If

Call-out

is enabled, the Service Processor calls to report the failure

displays

the operating system

surveillance

failure

code

on

the

operator

panel.

Operating System

Surveillance:

Provides the Service Processor with a means

to

detect

hang

conditions, hardware or software failures while the operating sys

running. It

also

provides the operating system with a means to detect the Servic

Processor failure by the lack of a return heartbeat.

Operating

system

surveillance is disabled by default. This

is to allow the user

operating

systems

that

do not

support

this Service Processor option.

Operating system surveillance can be enabled and disabled via:

Ÿ service processor Menus

Ÿservice processor Service Aids

Three parameters must be set for operating system surveillance:

1.Surveillance enable/disable

2.Surveillance interval

This is the maximum time in minutes the Service Processor should wait for a heartbeat from the operating system before timeout.
