5. Using

the Online and

Standalone Diagnostics

 

The

diagnostics

consist

of Online Diagnostics and Standalone

diagnostics.

Online

when

they

are installed, reside with

single user

mode

(referseredvice tomode) as

 

Ÿ run in maintenance mode (referredmaintenanceto asmode)

Ÿrun concurrently (referredconcurrentto asmode) with other applications.

If

the system

is not booted,

the Online Diagnostics

have

access

to

the

AIX e

and the AIX configuration data.

 

 

 

 

 

 

Standalone Diagnostics are packaged on removable media

and

must

be

booted

 

before they can be run. If

booted, they have no

Operating Considerations

 

 

 

 

 

 

 

 

 

 

 

 

Note:

When possible,

run Online Diagnostics in service

mode.

Online

Diagnostics

 

perform additional functions, compared to Standalone Diagnostics. Running Online

 

 

Diagnostics in service mode ensures

that

the

error

state

of

the

system

is

capt

NVRAM

for

your

use

in fixing the problem. The

AIX error

log

and

certain

SMIT

 

functions

are

only

available when

diagnostics are run

 

from

the

disk

drive.

 

 

Consider

the following items before using the diagnostics:

 

 

 

 

 

 

 

 

Ÿ When

diagnostics

are

installed,

the device

support

for

some

devices

might

not

get installed. If this is the

 

case,

that

device

does

not

appear

in

the

di

test

list when running

disk-based

diagnostics.

 

 

 

 

 

 

 

 

 

 

ŸSupport for some TTY terminals is optionally installed. If you attach a TTY

terminal to

a system

to run

diagnostics,

it

might not work correctly because t

AIX support

for the

terminal

might not

be

installed.
