IBM SY33-0193-00 manual Utilities, Introduction, Event

Maintenance

Analysis

Procedures

(MAPs)

The

maintenance

analysis

procedures

(MAPs)

describe

how

to

analyze

a

failure

that

has

occurred in an SSA loop.

Introduction

to Using

the

MAPs

Do not

turn

off the

system unit

when

servicing

an

SSA

loop,

unless

the

system

unit

needs

to

be

turned off for some other

reason.

Unit

power cables

and external

SSA

cables

that

connect

the

devices

to

the

system

can be

disconnected

while

that

sys

running.

To isolate the FRUs, do the actions and answer the questions given in the MAPs.

When instructed to exchange two or more FRUs in sequence, proceed as follows:

1. Exchange	the	first FRU in the list for a new one.
2. Verify	that	the problem is solved. For some problems, verification means running
the diagnostic		programs.

3.If the problem remains:

a. Reinstall the original FRU.

b. Exchange the next FRU in the list for a new one.

4. Repeat steps 2 and 3 until either the problem is solved, or all the related have been exchanged.

5. Do the next action indicated by the MAP.

Remember that disk	drives are fragile. Handle them with care and keep them well a
from strong magnetic	fields.

A Note on Configurator

Utilities

Text

in

this

section

refers

to

the

DOS

configurator. If you are using the

RSM (R

System

Management)

configurator,

all

event logger functions can be accessed from

the

Event

Logger

button on the main page. Diagnostic

functions

are

available

on each

Adapter

View

page.

The

Physical

view

in

the

RSM

is

equivalent

to the Disk Service Aids. Individual servi

actions,

such

as

Format,

Certify

and

Set

Service Mode are available on each

individu

resource

menu. Resource Views (Disks and

RAID-5
