IBM SY33-0193-00 manual Are Available, Finding the Physical, Finding the Device When

To

install

the

latest

version

of

the

adapter

microcode,

follow the same instructions as

for

disk

microcode

except

that

the

download

tool to use is

ISSAADLD

and

file

extensions are

.lxx,

where

xx

identifies the

adapter

type

(04

is

for

the IBM Seri

Adapter).

Note:

To

check

the

latest

instructions

on how

to

download

microcode,

read

the

README.TEXT

file

that

is

on

one

of the

diskettes

supplied

with

the

adapter.

Finding the Physical

Location

of

a

Device

The

physical

location

of a

device

(for

example, a disk drive or an SSA RAID Adapter)

not

reported

by

the

system

for

all

disk

subsystems, which

means

that the SSA Address

cannot be

used.

. The

address

of

an SSA device is related

to

the

position of

that device on the SSA loop. The address

can, therefore,

change

if

the

configuration

changed.

Finding the Device When

Service

Aids

Are

Available

When

the

service

aids are available, use the Identify function to

find

the

correct

drive

(see

“The

Identify Function”

on page 37). If

you want to

find

a

device

that

not

have

a

Check

light (for example, an adapter), you can either use

the

Identify

function to identify devices that are next to the adapter on the

SSA link, or use th

procedure

described

in “Finding the

Device When No

Service Aids

Are

Available.”

Finding the Device

When

No

Service

Aids

Are

Available

When

no

service

aids

are

available,

you

can

find

the

device

by

using

the

port

(P)

SSA-address (AA) values that are provided by some

service

request numbers

(SRNs).

Examples

of these

SRNs

are

43PAA,

44PAA,

and

45PAA.

The

port

(P)

value

can

be

a

number

0

through

3.

It indicates

the

port

connector

on t

SSA

adapter:

0

=

Connector

A1

1

=

Connector

A2

2

=

Connector

B1

3

=

Connector

B2

The

AA

value

is the decimal SSA-address

value. It

indicates

the

position of

the device

that

you

are trying

to

alongfind (countedtheSSA loop).

Use

the

port

value

to

locate the relevant connector on

the SSA

RAID

Adapter, then

follow the

SSA

cable

to realthe devicefirst. Include

other

adapters

as

real

devices

if

they

are

in

the

same

SSA link. Do not include

dummy devices.

The

first

device

that

you reach represents SSA-address count 0. Continue to follow the

SSA

links

from

device

to

device,

increasing

the

SSA-address count

by

1

for

each

device,

until

you

reach

the

device

that

is

indicated

in

the

SRN.
