The

startup

process

should

complete

within

five

minutes.

After

the

startup

process

completes,

the

new

RAID

controller

can

accept

I/Os

from

the

host

server

and

is

ready

to

be

managed

by

the

DS4000

Storage

Manager

client.

Note:

If

the

new

RAID

controller

is

not

recognized

by

the

DS4000

Storage

Manager

client,

use

the

Enterprise

Management

Window

to

rediscover

the

DS4100,

as

described

in

the

following

steps.

a.

Remove

the

entry

for

the

DS4100

from

the

management

domain

of

the

DS4000

Storage

Manager

client.

b.

Wait

at

least

five

minutes.

c.

Add

the

entry

for

the

DS4100

back

to

the

management

domain

of

the

DS4000

Storage

Manager

client.

Before

you

continue

with

the

next

step,

use

DS4000

Storage

Manager

to

verify

the

firmware

levels.

If

your

firmware

levels

need

to

be

updated,

reload

the

DS4100

storage

server

with

the

latest

version

of

the

controller

firmware

and

the

single-controller

option

NVSRAM

files.

Note:

Reloading

the

NVSRAM

files

will

clear

any

modifications

you

made

to

the

NVSRAM

default

settings.

If

required,

modify

your

NVSRAM

settings

as

needed

after

reloading

the

NVSRAM.

Continue

with

step

29

on

page

103.

If

the

firmware

version

of

the

replacement

DS4100

RAID

controller

does

not

appear

to

match

the

firmware

version

of

the

replaced

DS4100

RAID

controller:

The

startup

process

will

not

complete

and

the

RAID

controller

enters

a

Suspend

State.

If

you

cannot

make

management

connections

to

the

DS4100

controller

and

you

cannot

send

I/Os

to

the

RAID

controller

within

ten

minutes

after

powering

on

the

DS4100,

then

you

must

determine

whether

the

problem

is

a

result

of

a

mismatch

between

the

new

RAID

controller

firmware

and

the

firmware

used

by

the

configuration

database.

To

verify

that

the

DS4100

controller

firmware

is

mismatched,

restart

the

storage

server

and

monitor

the

drive

LEDs.

(Always

wait

at

least

30

seconds

between

the

time

you

turn

off

a

power

switch

and

the

time

you

turn

on

the

power

again.)

Wait

three

minutes

after

powering

on

the

unit

and

then

monitor

the

drive

LEDs

in

the

front

of

the

unit

for

at

least

four

minutes.

-

If

the

drive

LEDs

flash

one

or

more

times,

then

the

new

DS4100

controller

does

have

the

same

firmware

as

the

replaced

DS4100

controller,

but

another

problem

exists.

Verify

your

fibre

channel

and

Ethernet

connections,

and

then

perform

the

actions

recommended

in

step

29

on

page

103.

If

the

problem

persists,

call

IBM

support.

-

If

the

drive

LEDs

stay

solidly

lit,

the

new

DS4100

controller

has

different

firmware

than

the

replaced

DS4100

controller.

You

must

correct

the

controller

firmware

version

mismatch.

Retrieve

the

replaced

DS4100

controller

firmware

version

from

your

storage

subsystem

profile

and

download

the

appropriate

controller

firmware

files.

Note:

If

you

cannot

determine

the

controller

firmware

version

of

the

replaced

DS4100

RAID

controller,

call

your

IBM

support

representative.
