that

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

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.
