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
command 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”.
