1.

Make

sure

that:

v

All

cables

and

jumpers

are

installed

correctly.

v

The

correct

device

driver

is

installed

for

the

CD-ROM

drive.

2.

Run

CD-ROM

drive

diagnostics.

3.

CD-ROM

drive

tray

is

not

working.

(The

server

must

be

turned

on.)

1.

Insert

the

end

of

a

straightened

paper

clip

into

the

manual

tray-release

opening.

2.

Run

CD-ROM

drive

diagnostics.

3.

CD-ROM

drive.

CD-ROM

drive

is

seen

as

/dev/sr0

by

SuSE.

(If

the

SuSE

Linux

operating

system

is

installed

remotely

onto

a

blade

server

that

is

not

the

current

owner

of

the

media

tray

(CD-ROM

drive,

diskette

drive,

and

USB

port),

SuSE

sees

the

CD-ROM

drive

as

/dev/sr0

instead

of

/dev/cdrom.)

Establish

a

link

between

/dev/sr0

and

/dev/cdrom

as

follows:

1.

Enter

the

following

command:

rm

/dev/cdrom;

ln

-s

/dev/sr0

/dev/cdrom

2.

Insert

the

following

line

in

the

/etc/fstab

file:

/dev/cdrom

/media/cdrom

CD-ROM

drive

is

not

recognized

after

being

switched

back

to

blade

server

running

Windows

2000

Advanced

Server

with

SP3

applied.

(When

the

CD-ROM

drive

is

owned

by

blade

server

x,

is

switched

to

another

blade

server,

then

is

switched

back

to

blade

server

x,

the

operating

system

in

blade

server

x

no

longer

recognizes

the

CD-ROM

drive.

This

happens

when

you

have

not

safely

stopped

the

drives

before

switching

ownership

of

the

CD-ROM

drive,

diskette

drive,

and

USB

port

(media

tray).)

Note:

Because

the

BladeCenter

unit

uses

a

USB

bus

to

communicate

with

the

media

tray

devices,

switching

ownership

of

the

media

tray

to

another

blade

server

is

the

same

as

unplugging

a

USB

device.

Before

switching

ownership

of

the

CD-ROM

drive

(media

tray)

to

another

blade

server,

safely

stop

the

media

tray

devices

on

the

blade

server

that

currently

owns

the

media

tray,

as

follows:

1.

Double-click

the

Unplug

or

Eject

Hardware

icon

in

the

Windows

taskbar

at

the

bottom

right

of

the

screen.

2.

Select

USB

Floppy

and

click

Stop.

3.

Select

USB

Mass

Storage

Device

and

click

Stop.

4.

Click

Close.

You

can

now

safely

switch

ownership

of

the

media

tray

to

another

blade

server.
