Device
Suggested
action
“Media
not
found”
error
message
and
other
file
system
error
occur
on
a
blade
server
running
Linux
or
DOS.
Attempting
to
access
the
mounted
CD-ROM
drive
(media
tray)
after
it
has
been
switched
to
another
blade
server
results
in
I/O
errors,
even
if
the
media
tray
has
been
switched
back.
Note:
Because
the
BladeCenter
T
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.
v
If
a
blade
server
tries
to
access
the
CD-ROM
after
it
has
been
switched
to
another
blade
server,
a
“Media
not
found”
error
occurs.
v
If
a
blade
server
is
running
a
DOS
environment,
such
as
when
updating
firmware
on
the
blade
server,
the
firmware
can
be
interrupted
or
corrupted
when
the
media
tray
is
switched
away;
you
might
need
to
call
for
service
on
the
blade
server.
v
If
a
file
handle
was
left
open
by
switching
the
media
tray
away,
the
system
administrator
will
not
be
able
to
do
a
clean
unmount
(umount
command)
unless
the
unmount
is
forced
by
umount
command
parameters
(“lazy
umount”).
v
If
the
system
administrator
is
sharing
out
the
CD-ROM
drive
for
multiple
users,
that
network
share
is
broken.
Before
switching
ownership
of
the
media
tray
to
another
blade
server,
ensure
that
the
CD-ROM
drive
is
not
mounted
for
the
current
blade
server
owner
(check
for
open
file
handles
and
sharing
out).
If
a
firmware
update
is
taking
place
on
the
blade
server,
do
not
switch
the
media
tray
to
another
blade
server.
Linux
does
not
install
from
the
BladeCenter
T
CD-ROM
drive
or
will
not
start
afterward.
v
If
you
try
to
install
Red
Hat
Linux
to
the
blade
server
IDE
drive,
Linux
does
not
install.
v
If
you
try
to
install
Red
Hat
Linux
to
the
SCSI
drive
on
a
blade
server
expansion
unit,
Linux
appears
to
install
but
the
operating
system
will
not
start
properly.
v
If
you
try
to
install
SuSE
Linux,
Linux
does
not
install.
