	Cannot Access Exchanger Control Device on Windows
	2000/XP/Server 2003
	Data Protector uses the SCSI mini-port driver to control backup drives
	and libraries. Data Protector may fail to manage devices if other device
	drivers are loaded on the same system. The error message Cannot
	access exchanger control device appears when device operations
	such as media formatting or scanning are started.
Action	Run the <Data_Protector_home>\bin\devbra -devcommand on the
	system where the devices are located, to list all physical devices that are
	configured on the system. If any of the SCSI addresses have the CLAIMED
	status value, they are used by another device driver.
	Disable the Windows 2000/XP/Server 2003 robotic driver. For detailed
	steps, refer to the online Help index keyword “robotics drivers”.
