Working

with

Standalone

versus

Online Diagnostics

 

 

 

 

 

 

 

 

 

When

the

server

attempts

to boot in service mode (from either the default or

boot

list)

and

locates a

diagnostics CD-ROM before any

other

bootable

image,

the

the server starts standalone diagnostics.

 

 

 

 

 

 

 

Standalone

diagnostics

can

be

used

on

servers

installed

with

any

supported

 

operating

system.

 

 

 

 

 

 

 

 

 

 

 

 

 

When

the

server

attempts

to

boot

in

service

mode

(from either

the

default

or

boot

list)

and

first

locates

a bootable image

on

disk

drive

or

network connection,

the

server starts online

diagnostics.

 

 

 

 

 

 

 

 

Online diagnostics can be used only on servers installed with the AIX operating system.

Because

the

type

of diagnostics

started (standalone or online) depends on the

source

from

which

they are loaded, changing the boot list used during system s

can affect

which

diagnostics are

run.

Recommended Boot Options

The procedures under “Loading Diagnostics in Service Mode Boot” on page 2-7 produce the following recommended results:

ŸDefault boot list (F5 or 5 key) with diagnostics CD-ROM inserted loads Standalone Diagnostics.

ŸCustom boot list (F6 or 6 key) without diagnostics CD-ROM inserted loads Online Diagnostics, if AIX is installed on a device in the custom boot list.
