Advanced Server with SP3
applied. (When the CD or DVD
drive owned by blade
workstation x is switched to
another blade workstation, then
is switched back to blade
workstation x , the operating
system in blade workstation x
no longer recognizes the CD or
DVD drive. This happens when
you have not safely stopped the
drives before switching
ownership of the media tray [CD
or DVD drive, diskette drive,
and USB port].)
Note: Because the BladeCenter unit uses USB to communicate with the media
tray devices, switching ownership of the media tray to another blade workstation is
the same as disconnecting a USB device. Before you switch ownership of the CD
or DVD drive (media tray) to another blade workstation, safely stop the media tray
devices on the blade workstation 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
workstation.
