• See "Parts listing - BladeCenter HX5" on page 57 to determine which components are CRUs and which
components are FRUs.
• If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
All removable-media drive
problems. The media-tray
select button LED on the front
of the blade server is lit,
indicating that the blade server
is connected to the shared
removable-media drives.
The CD or DVD drive is
detected as /dev/sr0 by SUSE
Linux. (If the SUSE Linux
operating system is installed
remotely on a blade server that
is not the current owner of the
media tray [CD or DVD drive
and USB port], SUSE Linux
detects the CD or DVD drive as
/dev/sr0 instead of /dev/
cdrom.)
The CD or DVD drive is not
recognized after being
switched back to the blade
server running Windows 2000
Advanced Server with SP3
applied. (When the CD or DVD
drive that 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 or DVD drive. This
happens when you have not
safely stopped the drives
before you switched ownership
of the media tray [CD or DVD
drive and USB port]).

BladeCenter HX5 Blade ServerProblem Determination and Service Guide
Action
1. Check the function of the shared BladeCenter chassis resources. See "Solving
shared BladeCenter resource problems" on page 269.
2. Run the Setup utility and make sure that the drive is enabled. See "Using the
Setup utility" on page 20.
3. For SAS storage drive problems, make sure that the correct device driver is
installed. For the latest device drivers, go to http://www.ibm.com/systems/
support/.
4. Reseat the battery. See "Removing the battery" on page 76 and "Installing the
battery" on page 77.
5. Replace the battery. See "Removing the battery" on page 76 and "Installing the
battery" on page 77.
6. (Trained service technician only) Replace the system-board assembly. See
"Removing the system-board assembly - BladeCenter HX5" on page 140 and
"Installing the system-board assembly - BladeCenter HX5" on page 142.
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 auto ro,noauto,user,exec 0 0
Note: Because the BladeCenter chassis uses USB to communicate with the media
tray devices, switching ownership of the media tray to another blade server is the
same as disconnecting a USB device. Before you switch ownership of the CD or
DVD 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/Eject Hardware icon in the Windows taskbar.
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.
